AMD RDNA3 Second-largest Navi 32 and Third-largest Navi 33 Shader Counts Leaked

I highly doubt that the reason AMD is not selling as good as the company wants to (actually also true for intel and nVIDIA) is based on the performance of their chips. There are some very simple reasons right now the computer market is shrinking: World wide economics are moving towards a recesion (people don't spend on luxury products when there are headlines like "heat or eat") while we have a major conflict going on in Europe, China not having figured out how to cope with CoVid after almost 3 years by now and in the case of AMD the new platform just was/still is to expensive... oh wait... isn't that exactly the same thing with RTX 4000? Apart from that and I think someone mentioned that before: Why buy new (overprized) GPUs or CPUs when the last generations (yes not only the last one) still offer enough performance in most instances. Features like DLSS, FSR and XeSS prolong the lifetime of a product - which is good for customers, more money to heat AND eat.

Agreed.

Also, Nvidia probably wanted to cash in on crypto miners with 4000-series products, or at least expected them (miners) to clear store shelves of 3000-series ones before 4000 launched. Unfortunately for them, crypto crashed way within the development cycle of the 4000-series, stores got stuck with remaining 3000-series, which left them sitting between a rock and a hard place.

RDNA 2 wasn't very popular with miners, so AMD didn't have this problem. Their problems consist of what you said, and the RTX bandwagon.

Actually they humiliated nVidia, nVidia is wasting huge silicon on RT cores yet their latest RTX4XXX still suffer similarly to the previous generation.

If "RT cores" was close to what people think it is, we would not see 2000 series then 3000 series then 4000 series take roughly the same FPS hit with RT On.

It feels as if the main feature of RT is "it will cut your FPS in about half, no matter what card you use"...


Now, reasons for that is that there are, actually, many (at least 5) steps to do the RT. Only one of them is "hey, RT cores, here is my goddamn structure I've spent ages preparing, can you check it for intersections?".

Preparing/maintaining that structure is done using plain old shaders.
NV's approach is also very strict on which structure is supported. AMD allows to work with any.

Epic's Lumen, which you can see here demoed on PS5 in this video, is SLOWER with "hardware RT on".

"Control" was using different codepath (NV extensions) vs Microsoft's DXR standard, had it changed recently, by the way? If not, there is no conceivable future in which AMD GPU can beat NV GPU in this games.
NV is investing in RT hard, but there had been exceptions, that people tend to ignore. AMD GPUs are notably faster in WoW RT.
