Of course, it is still very early to introduce these products, and it can be expected that the first tangible versions may appear sometime in a year, but we’ll see. In any case, it is clear that RDNA 3 will arrive on the market at the earliest next year, but why not speculate a bit?

O AMD Navi 33 we have already mentioned, but what about the alleged hi-end model Navi 31? He should have a lot in common with Navi 33, simply because he has to use the same GPU with 80 CU, but in two copies side by side. –
Navi 31+32 = 2 chiplets for compute, 80 CU each, 1 IO die.
Navi 33 = 80 CU, monolithic.
Navi 31 is about 2.5x faster than Navi 21. Similar RT perf to nvidia (though a tiny bit slower like for like). ML still handled as lower precision ops

This would mean that thanks to two GPUs connected by a chiplet, in a similar way as today’s Ryzen processors with more than 8 cores, the best game graphics from AMD of the next generation should carry up to 10240 cores in a total of 160 CU (Compute Unit).
Nothing I can confirm 100% now, but from what I know Navi 31 is a 80 CU chiplet and top SKU has 2 of them.

According to the well-known leaker Yoshida, the Navi 31 should definitely be more than 2.5 times more powerful than the Navi 21, so we can think up to three times as much. Then we have a slightly weaker version of Navi 22, which is still supposed to be graphics with two GPU chipsets, and we also learn that AMD should move with the performance in ray tracing and catch up with NVIDII.
It looks like NVIDIA, which decided to push the Lovelace generation ahead of Hopper, will be behind AMD’s deployment of multi-chip GPUs, which could have an impact on which of these companies will offer a more powerful hi-end. Hopper is to use just more chips, while Lovelace should be a single-chip generation.
