US is capable of demanding a non-US company not sell a product
You’d think that the question should be how they are able to even dictate a US company to do that. Since all you ever hear on reddit is how US is just capitalism-uber-alles and damn corpos dictate the US state policy.
Yeah, that was the hope when the dual-issue shaders were being rumored as 12288 shaders on Navi31, almost 2.5x of 6900XT. Combined with arch improvements, higher clocks and 2nd gen RT, it would have easily done 2.5x of 6900XT performance.
Bulldozer was the exact opposite in terms of how the units behaved. Currently, it’s nvidia with the ‘make moar corez’ meme, and AMD could have been in the reckoning for the top spot in raster with a chip that has like a third of the shaders of nvidia’s.
AMD’s failing this gen is again not improving the clockspeeds. And of course, not making a chip the size of nvidia’s flagchip.
As for RT, I don’t think the difference is that big hardware-wise. AMD are overperforming in raster and nvidia have sort of a software monopoly right now with the PT game being done with their collaboration.

I agree in that I think the hardware difference isn’t that big as people are making it out to be, and AMD won’t catch up on software.
They do have some advantages, eyefinity for which I bought 6800XT and now that driver level FG.
right now AMD GPUs can’t do Path tracing at all
The later path tracing updates to classic games Serious Sam and Doom had the 6900XT close to 3070 performance. Now that intel is also in the fray and are said to have better RT hardware, if not on par with nvidia, they can also be used as a benchmark reference. The RTXDI updates to Portal and Cyberpunk have quite poor numbers on AMD and also on intel.
Arc770 goes from being ~50% faster than 2060 to 2060 being 25% faster when you change from RT Ultra to Overdrive.

I benched 6800XT vs 4090 in the old PT updated games and heavy RT games like Witcher 3 and Cyberpunk, and 4090 was close to 3.5x of 6800XT. The problem with AMD this gen is that they lost the clockspeed crown they had last gen and so they have to compete against 4080 in raster while being beaten in RT, instead of 6900XT matching 3070 in RT while outpacing it handily in raster.
The first thing is that AMD don’t build as big chips as nvidia. In raster, RDNA3 is extremely good against Ada shader-count-wise. As for RT, you can also think that they are comparatively better at raster instead. Double the N31 GCD and you have a chip that is best in raster and between 4080/4090 in RT.
The bigger problem is software and I doubt AMD will match nvidia there. The current AAA PT games are done with nvidia support and while it’s not nvidia-locked, it’d be great if intel/AMD optimize for it or get their own versions out.

This despite the intel cards’ RT hardware which is said to be much better than AMD if not at nvidia’s level.

The later path tracing updates to classic games of Serious Sam and Doom had the 6900XT close to 3070 performance. Earlier this year, I benched 6800XT vs 4090 in the old PT updated games and heavy RT games like updated Witcher3 and Cyberpunk, and 4090 was close to 3.5x of 6800XT. 7900XTX should be half of 4090’s performance then in PT like in RT heavy games.
