AMD Ryzen 7 8700G APU Zen 4 & Polaris Wonders!

AMD Ryzen 7 8700G APU The company formidable main processing unit (APU) with Zen 4 framework and Polaris designs, the AMD Ryzen 7 processor 8700G

The conclusions of the assessments for the Ryzen 5 processor from AMD 8600G had previously revealed this morning, and now some of the most recent measurements from the Ryzen 7 8700G APU graph G have been released made public. Among AMD’s Hawk A point generation of advanced processing units (APUs), the upcoming Ryzen 7 8700G APU will represent the top of the lineup of the The AM5 series desktops APU. That is going to have an identical blend of Zen 4 and RDNA 3 cores in a single monolithic package.

Featuring 16 MB of L3 memory cache and 8 megabytes of L2 cache, the aforementioned AMD Ryzen 7 8700G APU features a total of 8 CPU cores and a total of 16 threads built onto it. It is possible to quicken the clock to 5.10 GHz from its base frequency of 4.20 GHz. A Radeon 780M based on RDNA 3 with 12 compute units and a clock speed of 2.9 GHz is included in the integrated graphics processing unit (GPU). It is anticipated that future Hawk Point APUs would have support for 64GB DDR5 modules, which will allow for a maximum of 256GB of DRAM capacity to be used on the AM5 architecture.

The study ASUS TUF Extreme X670E-PLUS wireless internet chipset with 32GB of DDR5 4800 RAM was used for the performance tests that were carried out. Because of this design, it is anticipated that the performance would be somewhat reduced. The Hawk Point APUs and the AM5 platform are both compatible with faster memory modules, which may lead to improved performance. This is made possible by the greater bandwidth that is advantageous to the integrated graphics processing unit (iGPU).

The AMD Ryzen 7 8700G “Hawk Point” APU was able to reach a performance of 35,427 points in the Vulkan benchmark, while it earned 29,244 points in the OpenCL benchmark. With the Ryzen 5 8600G equipped with the Radeon 760M integrated graphics processing unit, this results in a 15% improvement in Vulkan and an 18% increase in OpenCL. The 760M integrated graphics processing unit (iGPU) has only 8 compute units, but the AMD 780M has 12 compute units.

In spite of the fact that the 760M integrated graphics processing unit (iGPU) has faster DDR5 6000 memory, performance does not seem to rise linearly whenever there are fifty percent more cores. It would seem that this is the maximum performance that the Radeon IGPs are capable of. The results of future testing, particularly those involving overclocking, will be fascinating. However, the Meteor Lake integrated graphics processing units (iGPUs) might be improved with better quality memory configurations (LPDDR5x).

With the debut of the AM5 “Hawk Point” APUs at the end of January, it is anticipated that the RDNA 3 chips would provide increased performance for the integrated graphics processing unit (iGPU). At AMD’s next CES 2024 event, it is anticipated that further details will be discussed and revealed.

GPU Industry Rant

I'm angry, angry about graphics cards.

Why?

Because what used to be a fun exercise in trying to find the best value or trying to find a good deal at a shoestring budget has turned into "how long do I need to wait to find something that isn't awful value".

It used to be that you could get a reasonably decent new gaming GPU for about $100-$150 and every new generation there'd be new cards in that price range that were a decent bit better. You used to be able to get a genuinely good gaming GPU at $150-250 with significant improvements every generation.

What used to be

It has soon been 4 years since the release of the GTX 1650, and about 3.5 years since the 1660 Super and 1650 Super. These three cards represent the last time there was a step forward at these two price points.

In 2016 we had the GTX 1050ti at $150, the RX 470 at $180 and the RX 480 at $200 ($250 for the 8GB model). The 1050ti was pretty awful value compared to the 25% faster RX 470, but it still beat previous generation $200 cards by a few percent. The GTX 1650 then at $150 just about matched the RX 470 in 2019, still not a great value improvement, especially since AMD released the slightly faster RX 570 at $170 in 2017, but at least you paid slightly less for about a match in performance. The GTX 1650 Super half a year later was about similar, matching or slightly beating the RX 580 (which in turn was a bit faster than the 480 and slightly cheaper) at $160, making for a small step up in performance compared to the RX 570. The 1660 Super at around the same time set you back $230 while providing about 25% more performance than a 1650 Super or RX 580, making it on par with 2016′s $450 GTX 1070, quite an improvement in value.

As for cards below $150, we've had nothing since the GT 1030 ($70 2017), RX 550 ($80 2017) RX 560 ($100 2017) and GTX 1050 ($110 2016).

Since then we've had

the GTX 1630, a card that costs $150 while performing somewhere between a 1050 and 1050ti, making it uncompetitive against the bad value 1050ti from 2016. The only way to make the 1630 look good is if you compared it to the 950 from 2015. The RX 6400, $160 for a card that gets beaten by the 1650 by a slight margin while also having issues in older PCs due to limited x4 PCI-E bandwidth. The RX 6500XT a $200 card that gets handily beaten by the 1650 Super with the same PCI-E issue as the 6400. The RTX 3050 a $250 (in theory at least) card that very slightly beats the 1660 Super. You're pretty much paying at least $20 more for unusable raytracing and the privilege of being able to use DLSS.

Cope

Some youtubers a while back went on about how "the age of the APU" is coming or something like that. Arguing that anything up to about $150 will be made obsolete by integrated graphics. They were technically correct, but only if you compare the latest and greatest iGPU in laptop CPUs, the Radeon 680M to the GTX 1630, which as I mentioned earlier is worse than a 1050ti, a $150 GPU that's coming up on its 7th birthday in a few months. Presumably the same 680M and possibly a 12CU RDNA 3 GPU will make it into some Ryzen 7000G APUs later this year, but even then I think top iGPU (which will be included in a CPU that'll be more expensive that it would've been to buy a cheap CPU + GPU combo back in the day) only might match RX 6400 performance or maybe 1650 performance, certainly not 1650 Super performance and absolutely not what ought to have been $150 performance this generation (which is to say something closer to the RTX 3050).

Hope

At least the used market is back to relatively normal, so if you want RX 6500XT performance but don't feel like paying $200 for it you can just buy a used RX 580 for like $90 or if you want better you can go for a 1660 Super for about $130 (both "buy it now" prices on ebay). The prices of these used cards are scaled quite appropriately from what new card pricing for the same performance levels ought to be.

The downside of buying older cards is that they don't always age that well. The GTX 9 and 10-series have aged like fine milk in the latest games (which is to say that relative performance to the 20 and 16-series is down by a lot) and AMD dropped support for their 2012-2015 lineup in 2021.

Additional notes

It is worth mentioning that the RX 6600 is currently available at $250 in the US when on a small discount and provides a good 25% performance uplift compared to the RTX 3050/GTX 1660 Super, however this pricing is not universal, the same card on German amazon is €280 or $300, on canadian amazon the best I found was 270 USD. Here in Sweden some part of increased prices is definitely due to inflation, 1660 Supers used to be around 2700 SEK, now an RX 6600 is at best 3200 SEK which is a pretty big change, sure it currently translates to just below $250 before our 25% sales tax, but that doesn't make it feel any better.

[ad_1] AMD has announced the Radeon RX 9070 at $549 and the RX 9070 XT at $599, both of which ship on March 6. The AMD RDNA 4 architecture and Radeon RX 9000-series GPUs were partially revealed at CES 2025, except they weren't part of AMD's keynote. Very little was known (officially) other than the names of the first two graphics cards for the family. That changes today, with AMD detailing many of the architectural upgrades, specifications, and more, during a video presentation. These will go up against the Nvidia Blackwell RTX 50-series GPUs and the Intel Battlemage Arc B-series GPUs and will likely join the ranks of the best graphics cards in the coming days.Like Nvidia's RTX 50-series graphics cards, AMD's RDNA 4 launch seems to have been delayed, though perhaps for different reasons. There were rumors that the cards would be revealed at CES 2025 and launched in January, then February, and finally March. That last is no longer a rumor, with the RX 9070 XT and RX 9070 set to go on sale on March 6 — and in typical fashion, the "MSRP" or base model cards will have reviews go up the day before, followed by the overclocked non-MSRP models on the launch date. Nvidia's RTX 5070 will likely land right around the same time, just to make things even more exciting.Image 1 of 44(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)But if you look at graphics card availability right now, what becomes immediately clear is that virtually everything is sold out or, at the very least, seriously overpriced. AMD has had difficulties with GPU transitions in the past, with the prior generation hanging around for too long and competing with the new parts. This time, it seems to have gone the opposite way, with RX 7000-series GPUs mostly having disappeared from retail shelves in December and January. Only the lower tier RX 7600 and RX 7600 XT are still in stock at MSRP (or close to it).The result has been dramatically increased demand for everything from mainstream to high-end graphics cards, and Nvidia's RTX 5090, RTX 5080, and RTX 5070 Ti all sold out almost instantly at launch. Will AMD's 9070 XT and 9070 fare better? We can hope so, but we suspect there's so much pent-up demand that even with another two months' worth of production and supply, it will still be insufficient. Hopefully, things will settle down later this year, but in the near term, we expect inadequate supplies and increased retail prices — and, yes, scalping.No doubt Nvidia's record profits driven by AI are a big contributor, and while AMD isn't selling quite as many data center GPUs, a lot of its wafer allocation from TSMC is likely going to data center CPUs and GPUs as well. Gamers are no longer the top priority for either company, in other words; for the time being, they just get the scraps that fall from the AI table.But enough sad talk. Let's check out the specifications for AMD's RDNA 4 GPUs, talk about architectural updates, and dig into all the other details. We even have pricing information, though as you can guess, that's worth about as much as the paper this is printed on. We'll continue updating this article as additional details become available, but for now, here's everything you need to know about the AMD RDNA 4 and Radeon RX 9000-series GPUs.RDNA 4 GPU specificationsHere are the known specifications for the RX 9070 series GPUs, along with placeholder information on the RX 9060 series. AMD did share the 9060 name at CES 2025, but no other details have been shared. There are rumors, however, which we've used to flesh out the table — these are indicated by question marks in the various cells.Swipe to scroll horizontallyGraphics CardRX 9070 XTRX 9070RX 9060 XT?RX 9060?ArchitectureNavi 48Navi 48Navi 48?Navi 44?Process TechnologyTSMC N4PTSMC N4PTSMC N4PTSMC N4P?Transistors (Billion)53.953.953.922?Die size (mm^2)356.5356.5356.5153?SMs / CUs / Xe-Cores645632?20?GPU Shaders (ALUs)409635842048?1280?Tensor / AI Cores12811264?40?Ray Tracing Cores645632?20?Boost Clock (MHz)297025202790?2700?VRAM Speed (Gbps)202020?20?VRAM (GB)161612?8?VRAM Bus Width256256192?128?L2 / Infinity Cache646448?32?Render Output Units12812896?64?Texture Mapping Units256224128?80?TFLOPS FP32 (Boost)48.736.122.9?13.8?TFLOPS FP16 (FP4/FP8 TFLOPS)389 (1557)289 (1156)183 (731)?111 (442)?Bandwidth (GB/s)640640480?320?TBP (watts)304220150?120?Launch DateMar 2025Mar 2025Apr–Jun 2025?Apr–Jun 2025?Launch Price$599$549$399?$299?The RX 9070 XT and 9070 columns should be fully accurate. We're reasonably sure there will be a trimmed-down RX 9060 XT using the same Navi 48 die as the 9070 cards, just with fewer CUs (Compute Units) and memory controllers enabled. Below that, things get murky.The RX 9060 could use a further binned Navi 48, or it could use Navi 44. Most of the details on Navi 44 are questionable at best, but we'll certainly find out more in the coming months. There might even be RX 9050-class GPUs at some point, but we've avoided listing those for the time being.Looking at the RX 9070 XT, it uses a fully enabled Navi 48 die that includes 64 RDNA 4 CUs. Combined with a 2.97 GHz boost clock and a 256-bit memory interface with 20 Gbps GDDR6 VRAM, the other specifications mostly come from straight mathematical calculations. The RX 9070 is mostly the same configuration, just with 56 CUs and a 2.52 GHz boost clock — substantially lower than its bigger sibling, though we'll have to wait and see what real-world clocks actually look like.Power targets also play a role in the final clock speeds, and where the 9070 XT has a 304W TBP (Total Board Power), the 9070 cuts that all the way down to 220W. That's probably a big factor in the 450 MHz difference in boost clocks.Raw compute works out to 48.7 TFLOPS FP32 on the 9070 XT and 36.1 TFLOPS on the 9070. On paper, that makes the XT up to 35% faster. In practice, we suspect the two chips will be quite a bit closer and that the actual clocks in most games may only be a couple hundred MHz apart, despite what the specs suggest.AMD has also given the Ray Accelerators and AI Accelerators in the CUs a massive overhaul compared to RDNA 3. For AI, each can do twice as many FP16 operations per cycle and they now support sparse operations. Sparsity can skip up to half of the zero multiply operations to potentially double performance, and it's a feature Nvidia has supported since its second-generation RTX 30-series GPUs. (AMD has also supported sparse operations on its CDNA family of GPUs for several years.)Moreover, the AI units also support FP8, INT8, BF8, and INT4 operations, with the 8-bit calculations being twice as fast as 16-bit, and 4-bit integers double that again. Put it all together, and you get 389 TFLOPS of sparse FP16 compute and up to 1557 TOPS of sparse INT4 compute.Keep in mind that the previous generation RDNA 3 architecture featured GPUs with up to 96 CUs and a 384-bit memory interface on the RX 7900 XTX, so while RDNA 4 GPUs are faster on a per-CU basis, AMD doesn't expect the RX 9070 XT to beat the RX 7900 XTX in all workloads.There's a lot more going on than the raw specs will tell you. First, let's cover the pricing and launch date, then move on to the architectural deep dive.RX 9000-Series Pricing(Image credit: Shutterstock)How much will the RX 9000-series GPUs cost? AMD has announced the Radeon RX 9070 will start at $549 and the RX 9070 XT will start at $599, placing them firmly in the "mainstream" segment. Given the current market conditions, however, it probably doesn't matter what AMD has given as the MSRP. Short-term, certainly, we expect the cards will all sell out and end up costing much more than the MSRP.As we said in the Nvidia Blackwell overview, for dedicated desktop graphics cards, we're now living in a world where "budget" means around $250–$300, "mainstream" means $400–$700, "high-end" is for GPUs costing $800 to $1,000, and the "enthusiast" segment targets $1,500 or more. AMD is going after the mainstream segment with the 9070 series, and possibly the lower mainstream and upper budget segments with future 9060 series parts.Depending on supply, as well as performance, the RDNA 4 series should be worth the price AMD is asking. More likely is that there simply won't be enough cards to satisfy the current demand, not for many months. Given the reasonably low-ish prices, don't be surprised if scalpers and retail markups step in and push the prices up.It's basically a repeat of the cryptocurrency GPU mining shortages, only this time it's caused by AI and demand from that sector may not go away for many years. Let's hope we're wrong, but the RTX 50-series launches so far have not been promising.RDNA 4 Release DatesWe listed the March 6, 2025 release date for the RX 9070 cards already, but AMD has also at least partially teased an RX 9060 family of GPUs. Will there be multiple cards or only one? Will there be lower-tier RX 9050 cards as well? The short answer: We don't know. The nebulous answer: Sometime between April and the end of the year, hopefully sooner than later.We've seen rumored die sizes for Navi 44 that suggest it's a much smaller chip, like more of a replacement for the current Navi 33 (RX 7600 series). If that's correct, it may not come out any time soon. There still appear to be plenty of RX 7600 and RX 7600 XT GPUs floating around, and that's because when those launched there were still a lot of similar performing Navi 23 (RX 6650 XT / RX 6600 XT / RX 6600) cards still available, at lower prices.The naming scheme from AMD suggests that the RX 9060 will compete with the RTX 5060 family. That would perhaps require a larger chip than what's indicated. But RX 7600 does technically compete with the RTX 4060, and there's no RTX 4050 and probably won't be an RTX 5050.Will AMD be making a "true budget" RDNA 4 chip? Again, rumors suggest that's at least possible, perhaps even likely. At less than half the size of Navi 48, AMD may try to create a $200~$250 graphics card to go after budget-minded gamers — and OEMs. Certainly it could get a lot more chips per wafer with the rumored 150~160 mm^2 die size.But if the cards then only sell for $250 or less? That hardly seems worth the effort, not when companies can charge tens of thousands for data center GPUs.RDNA 4 Core GPU ArchitectureImage 1 of 23(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)The above slide gallery covers the architectural briefing AMD provided in advance of today's reveal, including some of the specifications discussed above as well as finer details. AMD worked to refine the underlying architecture to improve per-CU performance in all major workloads: rasterization, ray tracing, and AI.Rasterization performance sees the smallest generational gains, but it's still about 40% faster than RDNA 3 according to AMD. Ray tracing performance is basically doubled, and AI performance is doubled for dense FP16 compute, with lower precision formats delivering even higher performance.The specific details of the rasterization improvements are a bit nebulous. RDNA 4 supports out of order memory requests, which AMD specifically notes as being helpful for ray tracing, but it can help rasterization tasks as well — we just don't have any details on how much. The other major change involves dynamic register allocation. RDNA 3 (and earlier) allocated registers for the worst case for shaders. By dynamically allocating extra registers only when needed, AMD provides an example use case where it could have an extra wave in flight. The slides show three waves versus four waves, which would be a 33% increase, but we don't know if that's representative of real workloads or just for illustrative purposes.Moving on to ray tracing, this is where AMD spent a significant amount of effort. It doubled the ray/triangle and ray/box intersection rates per RT unit as a start. THen it offers some enhancements including hardware instance transforms (rather than doing a lot of the work via GPU shaders), oriented bounding boxes, an improved BVH (Bounding Volume Hierarchy) structure and traversal, the above-mentioned out of order memory returns, and better ray hardware stack management.Most of the improvements come from the doubling of intersection rates and BVH compression, but the other aspects combine to deliver a solid improvement as well. How does RDNA 4 compare with Nvidia's latest hardware? That's not fully clear, but certainly it's going to do better per CU than what we saw with RDNA 3 and RDNA 2. It likely won't match Blackwell, but it might be better than Ampere and at least closer to Ada levels of performance.AI, as already noted, sees the biggest changes. Nvidia has been iterating on its AI tensor cores since the RTX 20-series, and even before that the Volta data center GPU had tensor cores. So Nvidia is on its fifth generation of AI matrix cores while AMD is mostly on its second generation — mostly because it looks like AMD took a lot of the work that's been happening in its CDNA GPUs and brought it over to RDNA 4.RDNA 3 CUs could do 512 FP16 operations per cycle, with no sparsity support, or 1024 INT4 operations per cycle. With RDNA 4, AMD doubles the baseline FP16 throughput for dense operations, doubles that again for sparse operations, and doubles that again for FP8 workloads — which are proving useful in the AI space. That's up to 8X higher AI throughput for FP8 on RDNA 4 compared to FP16 on RDNA 3, and the INT4 throughput sees a similar up to 8X improvement.AMD gave a real-world example of how this affects AI performance using Stable Diffusion XL. The RX 9070 XT with 64 CUs took on the RX 7900 XT with 84 CUs. That gives the older GPU a 31% advantage in compute units, but the 9070 XT ended up delivering very close to 2X the performance. That will prove very helpful for other AI and machine learning workloads, including ML-based upscaling and frame generation (see FSR 4 below).Alongside these changes, AMD has reworked some of the cache and memory hierarchy with RDNA 4. It didn't provide any clear details on what has changed, but it notes that this is the third generation of Infinity Cache. The capacity remains 64MB, the same as what was present on the 256-bit 7900 GRE and 7800 XT, but now the cache is again part of the monolithic chip, so it likely has better latencies and throughput.Get Tom's Hardware's best news and in-depth reviews, straight to your inbox.RDNA 4 Other Architectural ImprovementsRDNA 4 isn't just about core architecture upgrades. Along with the above rasterization, ray tracing, and AI enhancements, AMD has also upgraded a few other areas. One of the big changes is with the media encoding hardware. Last time we checked video encoding performance and quality, AMD came in last place, clearly behind Nvidia and Intel. It looks like RDNA 4 will close the gap.AMD says it has improved H.264 (AVC) quality by up to 25%, H.265 (HEVC) by 11%, and improved the AV1 encoding efficiency. It also has better support for AV1 and VP9 decoding and reduced memory accesses.Besides the quality improvements, RDNA 4 adds a dual media engine. Nvidia did this with its Ada architecture, and AMD seems to be taking a similar approach. It likely doesn't help all workloads equally, but AMD says it doubles the AV1 encoding throughput.Realistically, there's only so far you can go with improving video encoding quality, particularly with hardware encoders. Intel and Nvidia are pretty comparable, but AMD was behind on quality while being ahead on performance with RDNA 3. It sounds like RDNA 4 will continue to be faster while offering similar quality to the competition, which is a good thing.Another change with RDNA 4 is that AMD has added hardware flip queue support, which offloads video frame scheduling to the GPU. While Nvidia discussed something similar for MFG (Multi Frame Generation), it sounds like AMD's solution is focused on improving video playback by reducing CPU load, as opposed to being something to improve the scheduling of generated frames.Radeon Image Sharpening (RIS) has also been updated, to RIS2. This is a driver level sharpening solution that's based on AMD's CAS algorithm (Contrast Aware Sharpening), only now the quality is supposed to be better. It's a single click toggle to apply RIS2 across all APIs.Finally, RDNA 4 GPUs will support PCIe 5.0 interfaces. That doubles the throughput over the x16 link, though in practice most workloads likely won't see much benefit. Gaming in particular doesn't tend to need more than PCIe 3.0, or perhaps 4.0, when using a full x16 connection. However, AI and certain content creation tasks can benefit from the added bandwidth. Don't be surprised if the future Navi 48 chips and possibly even the RX 9060 XT cut the interface down to x8 or even x4 widths.(Image credit: AMD)Sticking with GDDR6 VRAMOne thing that isn't changing from RDNA 3 is the memory support. While Nvidia has moved all of the announced Blackwell RTX 50-series solutions to GDDR7 memory, AMD will continue to use GDDR6 memory, clocked at up to 20 Gbps. Coupled with a 256-bit interface on the 9070 XT and 9070 GPUs, that results in 640 GB/s of memory bandwidth. That's the same VRAM capacity as the RX 7900 GRE and RX 7800 XT, and also the same as Nvidia's RTX 5070 Ti and RTX 4070 Ti Super.The 64MB Infinity Cache will improve the effective bandwidth, though AMD didn't elect to provide any estimates of cache hit rates so far. The RX 7900 GRE and RX 7800 XT both had 64MB Infinity Caches, and AMD provided effective bandwidth rates that were about 4X the base memory bandwidth with those GPUs, so we'd anticipate the Navi 48 GPUs will see similar results.It's also possible that further improvements to the Infinity Cache have made it less critical for AMD to move to GDDR7 at present. Considering that Nvidia gets a 40% improvement in raw bandwidth from 28 Gbps GDDR7 compared to AMD's 20 Gbps GDDR6, that might seem like a sizeable advantage. However, effective bandwidth after factoring in the large caches may not be all that different.Plus, there's only so much bandwidth needed to drive a 64 CU GPU. Nvidia's RTX 5070 Ti for example has 70 SMs (Streaming Multiprocessors), which are roughly analogous to AMD's CUs, and the 5070 Ti has a 48MB L2 cache. Putting a larger 64MB L3 cache with fewer GPU processing clusters could reduce the need for higher memory speeds.AMD continues to use 16Gb (2GB) GDDR6 modules, and we're unaware of any companies currently pursuing 24Gb (3GB) capacities. That's one area where GDDR7 support could prove beneficial for Nvidia in the future, though so far only the RTX 5090 Laptop GPU is using the higher capacity chips.Monolithic GPUs, Built on TSMC N4POne of the interesting changes with RDNA 4 is that AMD is, at least for now, ditching the GPU chiplets approach. It may come back to that in the future, but the Navi 48 and presumably the rumored Navi 44 will be monolithic chips. Along with that design choice, AMD is also upgrading from TSMC's N5 process node used on RDNA 3 to the N4P node for RDNA 4.N4P provides for modest improvements in performance and efficiency compared to the N4 node, which in turn refines the base N5 node. Our understanding is that N4P may introduce some additional metal layers, and N4 used more EUV than N5. What's not entirely clear is how N4P compares to 4N and 4NP — the "for Nvidia" variants that are used with Hopper, Ada, and Blackwell. It's probably pretty similar in most respects, which means that AMD will be on node parity with Nvidia this round.But AMD isn't really trying to take down Nvidia's top GPUs. The lack of GDDR7 memory and the lack of a larger design prove this. The Navi 48 chip will house 53.9 billion transistors in a 356.5 mm^2 die. Nvidia's GB203 used in the RTX 5080 and 5070 Ti contains 45.6 billion transistors in a 378 mm^2 die... which might suggest AMD actually has a superior process node and/or design. But we can't really conclude that.While die sizes are pretty straightforward, transistor counts are not. They're more of a mathematical estimate, and there are different ways of counting what constitutes a "transistor." Perhaps AMD does have a denser design with more transistors, perhaps not. Ultimately, we'll have to see how the various GPUs perform.One interesting side note here is that Navi 31, the top solution from the RDNA 3 family, had a 300 mm^2 GCD (Graphics Compute Die) with six 37.5 mm^2 MCDs (Memory Cache Dies). I wondered when AMD revealed the specs just how much it was actually saving by going the chiplet route. The GCD had 45.6 billion transistors, which means the overall transistor density — looking at the RDNA 3 GCD compared to the RDNA 4 monolithic design — is basically identical (152 MTrans/mm^2 on Navi 31 GCD compared to 151.2 Mtrans/mm^2 on Navi 48).But let's not get too carried away. It's known that scaling on external interfaces — like the GDDR6 memory controllers — is quite poor with newer process nodes. Navi 31 used twelve 32-bit controllers while Navi 48 has eight 32-bit controllers. If AMD had attempted to make a 384-bit interface on a monolithic design, it would have certainly required a larger chip. Putting that on an older process node for the prior generation did make financial sense at the time, and may yet prove a smart approach for a future AMD product.No "Made By AMD" Reference Cards(Image credit: AMD)If it wasn't clear yet, AMD will not be making or selling its own reference model RX 9070 series graphics cards. Despite providing some slides of what appear to be MBA (Made By AMD) cards, these are merely graphical renders rather than photos of actual hardware. There were certainly prototype cards created during the design, testing, and validation process, but what those looked like isn't really important.All of the RX 9070 series graphics cards will be made by AMD's add-in board (AIB) partners. That means two things. First, we'll see a lot of variation in final clock speeds and power draw, not to mention things like the number of fans and RGB lighting. But more importantly, it means AMD has a lot less say in the actual retail graphics card prices.Very likely AMD has a requirement that all of the AIBs have at least one model for each GPU that will be nominally priced at the stated MSRP. Beyond that, however, all bets are off. "Here's our RX 9070 XT Red Herring for $599... and we sold all of those. Sorry! But you can pick up our Redder Herring OC model for $799!" We saw something like this with the RTX 5070 Ti cards, where there also isn't a reference model from Nvidia.Long-term, if there's insufficient supply to meet the demand, most AIBs are going to produce higher tier models with a few minor extras and drastically inflated prices. If on the other hand the supply catches up to demand, then it's easy enough to drop prices as needed.FSR 4 and HYPR-RXImage 1 of 28(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)Besides the hardware, AMD has been working on a variety of feature improvements. The biggest one is undoubtedly FSR 4. The fourth iteration of AMD's FidelityFX Super Resolution (FSR) algorithm, it will break with tradition in a couple of key ways.First, FSR 4 will leverage the more potent AI accelerators in the RDNA 4 GPUs. At launch, it will require an RDNA 4 GPU. Down the road a few months, AMD may try back-porting the algorithm so that it can run on RDNA 3 and maybe even RDNA 2 GPUs... but it seems unlikely.Instead, FSR 4 will basically co-exist with FSR 3.1, or rather, the non-AI upscaling will continue to be offered. It's not entirely clear exactly how this will play out, but keeping everything unified under one name makes more sense. What we do know is that AMD plans to allow gamers to use the more potent FSR 4 algorithm on games that have FSR 3.1 support. Will that happen automatically or require a driver settings toggle? It seems like the latter but we'll have to wait and see.FSR 4 isn't just for upscaling, either; it also has frame generation. From our understanding, both upscaling and framegen will use the AI accelerators of the RX 9000-series GPUs. AMD also says RDNA 4 is "neural rendering ready" without really going into further detail. Presumably that's related to Microsoft's new Cooperative Vectors feature, which is something Nvidia also talked about with Blackwell.We've asked for additional details on how FSR 4 works, in terms of the computations. AMD hasn't responded, but one slide does note that the RX 9070 XT offers "up to 779 TOPS AI Acceleration" while talking about FSR 4. Now, that's either dense INT4 operations or sparse INT8 operations, as the 9070 XT hits double that figure for sparse INT4, but we don't have a direct answer on whether the algorithms are using INT4 or INT8 yet. Either way, that's a lot more theoretical compute than what you can get from prior generation AMD GPUs, which is why we don't anticipate the AI upscaling and framegen models getting backported.We also asked if FSR 4 was using a transformers-based network or a convolutional neural network. DLSS 4 offers better image fidelity than DLSS 3 by using transformers, and AMD may have skipped the CNN approach since it's late to the AI-powered upscaling and framegen party. However, we don't have a direct answer yet. We do have some image quality comparisons from AMD, in the slides above, and FSR 4 definitely looks better than FSR 3.1.As with Nvidia's use of performance mode upscaling with framegen, we don't generally focus on the promised performance after all these extras. Framegen in particular is very heavy on marketing in our experience. It's less problematic when you already have a high base framerate, but then it's also less necessary when you're already getting 100+ FPS.AMD says it will have over 30 games with FSR 4 enabled for the RX 9070 series launch, with 75+ games coming in 2025.AMD also talked about HYPR-RX, which combines a variety of driver-level performance boosting features and can be enabled with a single click. We've poked at it a bit in the past, and it can be useful in some cases, but we prefer sticking with apples to apples comparisons. If you're just playing games, however, enabling HYPR-RX to apply all of the features including FSR/RSR, Anti-Lag, Radeon Boost, and AFMF 2 could be useful.AMD also has a new AFMF 2.1 release that imprves the quality of the algorithm, reducing ghosting, improving fine features, and detecting and handling overlays better.Drivers and SoftwareImage 1 of 27(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)(Image credit: AMD)The last item AMD discussed is its new Adrenalin 25.3.1 drivers along with some new software. While most of the driver interface will be familiar to AMD GPU users, there are some new additions along with some behind the scenes changes. AI plays a role in both areas. We've already discussed FSR 4 upscaling and framegen, so let's talk about the other AI uses.First, AMD is using AI to help find rendering errors and to detect instability and other issues. AMD claims its new 25.3.1 drivers will be perhaps the best and most stable drivers it has ever released, with fewer rendering errors. We'll have to wait and see how that goes...Moving on, similar to Nvidia's Chat RTX and other tools, AMD is providing some easy to access AI-powered features. These are all managed by a new AMD Install Manager that sits alongside the usual AMD Software in your system tray. Besides your GPU drivers, it can also detect if you have an AMD platform and keep your chipset drivers updated. And then there are some new extras: AMD Chat, AMD Image Inspector, and the AI Apps Manager (among others).AMD Chat is a chatbot designed to answer questions specifically about your PC hardware and GPU. You can ask it about GPU temperatures, performance, and more. It's a hefty 25GB download, though, so you might not want to install if it you're low on space — or if chatting with your PC isn't something you plan on doing.The AI Apps Manager provides a list of software and utilities that can use AI that are installed or available to install. So if you have Adobe CC, some of those apps might show up. Or you can use it to install Amuse, AMD's tuned AI image and video generation tool.Finally, the Image Inspector is a feature to help with finding and reporting rendering errors and bugs. AMD is already using AI to help it find issues internally, and the Image Inspector is an opt-in feature that allows you to participate. Using spare GPU resources (so it won't go crazy and use all your GPU power if you're in a demanding game), it can automatically capture rendering errors and submit them to AMD, should you enable the feature. It sounds interesting, but we suspect there might be a performance hit still, even if it's small.The GPU landscape(Image credit: Shutterstock)Frankly, RDNA 4 feels like what AMD should have been doing with RDNA 3 rather than pursuing the abandoned-for-now GPU chiplets approach. AMD has finally decided to put serious effort into ray tracing hardware and AI in its consumer product line. We can understand why RDNA 2 was lacking in these areas — Nvidia's GeForce RTX feature set probably caught the company off guard — but when RDNA 3 arrived in 2022, it really needed to do more and be more.What's interesting is that all of these new hardware features haven't caused a massive bloat in the die size. Navi 48 is 357 mm^2 on a 5nm-class node (N4P). Navi 31 was 300 mm^2 on a 5nm-class node (N5), with Infinity Fabric links to the external memory and cache chiplets. Rip out those links, rework the cores, and this was all possible several years ago. Which is obvious, since Nvidia already did that, but it felt like RDNA 3 doubled down on the "ray tracing and AI aren't really that important" marketing and got left behind. RDNA 4 finally rights that misstep, or at least attempts to. Now we just need to see how the actual hardware performs in a variety of tasks.AMD's RDNA 4 GPUs will have to compete with Nvidia Blackwell RTX and Intel Arc Battlemage solutions. As we discussed already, supply and availability of all graphics cards has become quite poor of late. (Yes, that's a sarcastic understatement.) Every recently launched GPU has sold out quickly, with many cards then selling at prices far above the original MSRP. It started with the Arc B580 and became especially painful with Nvidia's Blackwell launches.Things aren't going to get better in the near term. The big issue is that there are a lot of companies competing for a limited supply of silicon manufacturing. TSMC only has the ability to process so many wafers in a month. Right now, AMD, Apple, Intel, and Nvidia are all using TSMC for various chips, and there are plenty of other companies as well — Broadcom, Facebook, Google, Amazon... the list can get quite large.Even if a company pays for a certain number of wafers in a given month, what to do with those wafers is still up for debate. Just looking at the main PC companies, AMD could make RDNA 4 GPUs on TSMC's N4P node, sure. Or it could make Zen 5 CPU chiplets for both Ryzen and EPYC CPUs, CDNA 3 data center GPUs (MI300X), other Ryzen APU designs for laptops and handhelds, or the future CDNA 4 GPUs that are likely coming this year. Nvidia has Grace CPUs, Hopper and Blackwell data center GPUs, NVLink processors, Ada Lovelace previous generation GPUs, and the new Blackwell RTX GPUs that are all using variants of TSMC's 5nm-class nodes. And Intel has leveraged TSMC for all or part of its Arrow Lake, Lunar Lake, and Battlemage product lines.Nvidia made record profits last year of $130 billion, primarily driven by AI. Its consumer gaming division only accounted for $11.35 billion, 8.7% of the total. And going forward, Nvidia will likely invest even more heavily in data center GPUs. That will eat up a lot of wafers, needless to say, and gaming will have to compete for its share.The good news is that more manufacturing capacity is coming online. A lot of that will likely go to create more AI processors, but the more capacity that exists, the more likely it is for other, less profitable chips — like consumer GPUs — to get made. And maybe AMD and Intel will try to grow their gaming GPU divisions while Nvidia is otherwise occupied. Or maybe Nvidia will treat gaming as a passion project that started the company and so it will try to ensure at least a reasonable number of chips get made. Maybe, maybe...Whatever happens, what's clear right now is that, as long as AI continues to grow as an industry, gaming GPUs are now a lower priority item for most of the biggest players in the graphics space. Let's hope that, like cyptocurrency mining, this turns out to be just a passing phase. But we wouldn't bet the farm on that. [ad_2] Source link
