Bad news correction from yours truly for AMD fans.
I never watched AMD's full event video, but I noticed the Techpowerup figures I quoted Thursday above were from previous rumors, not from the event itself, and hadn't been updated. Now they have. Most importantly, the 7900 XTX and 7900 XT shader counts were halved in concordance with what was shown at the event.

It gets worse. Unless I'm mistaken, Techpowerup's throughput figures are inaccurate even after the update. Because due to the new feature of the decoupled clocks there is now a separate "Shader Clock", and unlike the "Gamer Clock", which as I previously mentioned seems to be a responsible new specification standard AMD introduced to avoid misleading consumers where none was needed, the shader clock will actually be used for throughput calculations. In this case, it means the pixel throughput and FLOPS will be reduced. It also means ray-tracing performance will be reduced.
So things look a bit more competitive, but in reality, it probably doesn't change my former assessment much at all. Because bear in mind the previous generation already showed us that processing power doesn't matter nearly as much as we previously assumed. For example, the 6900 XT barely has higher FLOPS than the RTX 3070: 23.04 FLOPS vs. 20.31 FLOPS. And it has far less than the RTX 3080's 29.77 FLOPS. Yet it still mollywops both due to superior pixel and texturing performance. But now, at least, NVIDIA's 4080 has one lone crutch to lean on-- superior FLOPS.
Against the 4080, the 7900 XTX:
- +83% pixel throughput
- +26% textel throughput
- +50% VRAM (+8GB)
- +29% VRAM bandwidth
- -42% FLOPS
- +16% ray-tracing performance
- No tensor cores
- -17% price (-$200 USD)
Also,
@Slobodan, with that shader clock adjustment, there's no longer any question, the XTX is the way to go. Far, far better value.
