wccftech AMD RDNA4 Rumored Specifications: Monstrous 129 FP32 TFLOPS GPU, GDDR7, 3.5 GHz Clock Rates And More

One of the things that was lacking with AMD’s RDNA3 architecture was the ray tracing and AI/ML performance and AMD is looking to fix that with RDNA4. Caches will get big upgrades and 3rd Generation Infinity Cache is going to be rolled out along with a new data prefetch system. WMMA (Wave Matrix Multiply-Accumulate) V2 will also enable 2x the performance per CU for (presumably) matrix instructions allowing full SIMD lane usage. Even though the total increase in CUs is around 50%, the performance increase generation over generation is 100% - which is superb to hear.

This is what I've heard. It will be really interesting to see what happen will when AMD makes RT a priority and has a more mature chiplet design.

...true mGPU chiplets in a GCD (GCXs ?) is something I have been posting about at EHW for about three years or so now (hope springs eternal), the most recent one > here. The key will be the infinity fabric or whatever they're going to call it between GCXs.

 

...performance gains by future AMD and NVidia (and Intel ??) GPUs should continue to be breathtaking. I am in the software field and as such usually have a lot of equipment handy for work and play...the last few gens have made some pretty big leaps already but with die shrinkage and mGPU, it should be quite a feast. 

 

For comparison, two x 2080 Ti in NVLink managed just over 21,000 in Port Royal (and 12,000 in Superposition 8k). The single 6900XT is around 12,000 in Port Royal (7.200 in Superposition 8k) while the 3090 Strix hits about 16,000 in Port Royal (and close to 9,000 in Superposition 8k). Those were the previous years' goodies...now, my 4090 hits almost 30,000 in Port Royal and just under 17,000 in Superposition 8k...quite a change over the last few years, and no reason to expect that this trend will stop (subject to potential delays via the economy).

 

Finally, driver technology (think alphabet soup of RTX, FSR, DSR, DLSS3, Frame Insertion, NV Reflex....) will also have to play a major role with the new hardware over the coming years.

I'm guessing we'll see an RDNA3+ first (think like Zen+ that ironed out some early issues with Zen 1), and then yeah makes sense that RDNA4 then should be hopefully a nice Zen 2 moment for RTG. 

 

Problem with AMD is its always the next thing that's supposed to be the big winner. Its too bad really, they won a lot of mindshare with RDNA2, but then blew it with RDNA3.

I don't think they've blown it yet. The 7900xt/xtx despite it's flaws it's still a better value for the money compared to Nvidia right now, at least on pure performance. If they can iron out the issue causing more variable clock speeds before they release any more cards, they can definitely turn this around. Neither team has shown what the mid range is going to look like. I think whoever release a card that non-enthusiasts actually want to buy first will be the mindshare winner this round, and AMD and Nvidia both still seem a ways off from doing that. Given how upside down the GPU market is, there is plenty of room to correct these mistakes right now. No one expected AMD to win the enthusiast level race anyway. 

AMD stopped making the RX6800 pretty early, as that was a sort of rushed out card that they felt had too much ram for the GPU power, so they replaced it with the RX6750XT which has less ram. No reason they can't do that again and phase these first batch cards out over time.

Bigger issue is AMD was pretty transparent in the RDNA2 announcement and that included comparisons to the competition and for the most part their charts were fairly accurate. Fast forward 2 years and the RDNA3 announcement was quite different. Lot of "up to" performance claims that were one offs, not the average, and so they ended up in a situation that overhyped the 7900XTX and so when it released and average performance was down from what they tried to paint it as, well yeah they blew it. Then all the talks on gen on gen efficiency gains were flat out false. Yeah, they totally botched the launch and the goodwill they built up with gamers following RDNA2.

 

I agree with you on the 7900XTX being a good value card relative to the competition, but it looses a lot to (power efficiency, RT), and frankly I started to see 4080's that sat on shelves at my local Micro Center start selling out after the RDNA3 launch. Also the 7900XT is not good value at all and is definitely overpriced.

 

If we want to talk about how AMD handled expectations, marketing, branding, pricing, performance claims, they did absolutely blow it. Also the cards feel rushed. I get why they did it, but clearly they have issues. It's a botched launch in my mind.
