AMD RDNA4 Architecture Speculation

I’m really not getting why you guys think this is a marketing problem for AMD.
My only problem is this:

The highest AMD FSR4 option (9070XT) is going to be slower than the highest FSR3 option (7900XTX). This creates confusing dynamics for high end AMD buyers. Other than that I am all for AMD going with a clean break with FSR4.

Isn’t the 7900XTX EOL? It’s not really a buying option going forward.

Obviously the new GPU's will be a chunk slower than the better Navi 31 GPU's in normal performance benching and all, but if FSR4 is a worthwhile leap over FSR2 in image quality, could you potentially achieve a similar image quality as one of those Navi 31 GPU's(using FSR2) with similar performance? Improving reconstruction techniques is essentially the equivalent of a performance boost because you can (theoretically) achieve a target image quality with a lower resolution than before.

So like, with a 7900XTX, you're using FSR2 Quality, but perhaps a 9070 with FSR4 Balanced looks as good? That negates a lot of the 7900XTX's raw performance advantage because it's having to render a higher resolution.

That said, going by PSSR, I'm not expecting it to be some completely linear upgrade, and more 'better overall, but different'. Bah, it's so annoying they didn't show anything.
 
The fundamental issue here is there aren’t enough high end amd buyers to move the needle. Thus their focus is on price to performance at the xx70 series range vs nvidia. And I’d speculate their delay is to let nvidia give data points first to then price and pivot from.
 
With RDNA 4, AMD claims generational SIMD performance increase on the RDNA 4 compute units. The 2nd Gen AI accelerators will boast of generational performance increase, and AMD will debut a locally-accelerated generative AI application down the line, called the AMD Adrenalin AI, which can generate images, summarize documents, and perform some linguistic/grammar tasks (rewriting), and serve as a chatbot for answering AMD-related queries. This is basically AMD's answer to NVIDIA Chat RTX. AMD's 3rd Gen Ray accelerator is expected to reduce the performance cost of ray tracing, by putting more of the ray tracing workload through dedicated hardware, offloading the SIMD engine. Lastly, AMD is expected to significantly upgrade the media acceleration and display I/O of its GPUs.

We also got our first peek at what the "Navi 48" GPU powering the Radeon RX 9070 series looks like—it features an unusual rectangular die with a 2:1 aspect ratio, which seems to lend plausibility to the popular theory that the "Navi 48" is two "Navi 44" dies joined at the hip with full cache-coherency. The GPU is rumored to feature a 256-bit GDDR6 memory interface, and 64 compute units (4,096 stream processors). The "Navi 44," on the other hand, is exactly half of this (128-bit GDDR6, 32 CU). AMD is building the "Navi 48" and "Navi 44" on the TSMC N4P (4 nm EUV) foundry node, on which it is building pretty much its entire current-generation, from mobile processors, to CPU chiplets.

 
So like, with a 7900XTX, you're using FSR2 Quality, but perhaps a 9070 with FSR4 Balanced looks as good? That negates a lot of the 7900XTX's raw performance advantage because it's having to render a higher resolution.
That's very logical indeed. However, reviewers and buyers should also apply the same logic with DLSS vs FSR comparisons. A 4080 with DLSS Performance should be compared to a 7900XTX running at native FSR or FSR Quality.

Isn’t the 7900XTX EOL? It’s not really a buying option going forward.
What would be the upgrade path for a 7900XTX owner?
 
Ian Cutress was invited to an AMD post-conference conversation and in short, AMD wants to do an event just for RDNA 4, to talk about ray tracing and FSR 4, with demonstrations of the technologies.


Why do a press briefing now then? This still looks like a last minute change of plans. Wonder what is the reason.

That wall of text could be summarized into a single line: we are waiting on NVIDIA's pricing and see where we go from there!

Easy. 5070 Ti or 5080 or keep enjoying your 7900XTX.
Exactly! The only path forward for such a buyer is NVIDIA, which is why I said AMD marketing has a tough job convincing such buyer to stick with AMD.

Should have announced that and specified the date then. They could have shown a teaser of it, and at least announced the GPU lineup. They could have then stated "Hey, we'll have a Radeon dedicated press conference in the near future, stay tuned!" but as it was here today.. it just is obvious they want to see what Nvidia prices their GPUs at.. instead of charting their own course.. as usual.

This was a great read. It definitely softened the blow for me from the horrible CES coverage. It’s 100% obvious from those answers that they’re waiting for Nvidia to make the first move on pricing.

This bit was interesting. If you were to listen to lots of loud voices around the internet you would be led to believe that gamers don’t care about RT and they hate upscaling.

Could you maybe rank your priorities for RDNA 4, why you picked them, why you ranked them so high?

I would say our number one priority is focusing on improving performance in the areas that gamers care about most. In this generation, you'll see big ray tracing improvements, big MLOps improvements for things like FSR4 and ML Super Resolution.

The pricing wasn't in the press briefing though which means that it likely wouldn't have been shown in live stream either.
It's also arguably easier to omit just the pricing (if it was there) instead of cutting the whole RDNA4 segment.
This just seems weird. Maybe the dedicated event isn't that far off?
 
They also might not have an idea of where to position the GPUs relative to Nvidia's upcoming competition. It's been discussed elsewhere but there is a lot of unknowns and uncertainity about what Blackwell will actually bring.

With the 9950X3D you saw them confidently state it's positoning against Intel.
 
There's a reason why companies often compare new products to couple gens down, people upgrading every gen is a small group

I’m on a 4 year cycle. Just about getting to the point where my 3090 is struggling with some titles. It helps a lot that I’m usually 6-8 years behind on game releases.
