Somebody should bench the 5080 with downclocked memory then, to see how much that impacts performance
That's software RT (SVOGI), there's no hardware acceleration happening
Huh? According to AMD the XT delivers 5070 Ti performance in raster at roughly the same power, meaning perf/W is now equal. Also the Ti is GB203's salvage, you have to compare to the 5080 for perf/area. GB203 is around 6% bigger than Navi48, but the 5080 should be around 15% faster, so perf/area...
AMD clearly showed bigger gains with RT than without, so cache doesn't seem to be a huge hindrance. 7800 XT with 64MB was also a bit faster in RT than 6800 XT with 128MB.
Yeah, it was raised after the announcement
I think it's possible, at least in 1080p. The 6800 is around 35% faster than the 7600 XT, and N44 has the same amount of CUs but 40% faster CUs thanks to RDNA4. For higher resolutions the 6800 has a big cache and bandwidth advantage though.
Took only two generations to turn my 6800 into a 1080p card, that hurts
He makes so many wrong claims I don't even know where to start. He says the 9070 XT is slower than the 7900 XT (wrong), the latter has 50% more memory (also wrong) and it pulls 4W more (you guessed it, wrong), all in one...
Considering GB203 has fewer transistors despite having more SMs and the architectural improvements, my guess is Nvidia reduced L2 cache size. Potentially halved it to 32MB. To make up for that they use GDDR7 now.
I don't really get that. While GB202 might be out of reach, they could have made a GPU that is 1.5x N48, even after killing off chiplet RDNA4. The rest of the Blackwell looks mighty disappointing. The 5080 is only 15% faster in rasterization than the 4080, which means it's only 10-15% faster...
These numbers seem to be vs. the original 40 series. That would mean the 5070 is actually slower than the 4070S without AI, the 5070Ti is 5% faster compared to the 4070TiS and the 5080 is 10% faster than the 4080S.
Apparently Nvidia mentioned performance numbers without DLSS/AI.

Those numbers fit better to the increase in shader count, but oh boy
Stop comparing it to the previous generation and look at the 5070 instead. It's very possible the 9070 XT is 20-30% faster in raster and just about as fast in RT. Nvidia on the other hand has a feature advantage, especialy with DLSS. With DLSS 4 it will be possible to override the DLSS version...
That would be suicide for their mobile CPU business, server GPU business (which made over $5 billion in 2024) and for their semi custom business. Not everything revolves around PC gaming.
