And it seems clear why new improved SM did not make any difference - they can't do FP32/INT at the same time now! AFAIK before Ampere/Ada they could do FP32+INT or FP32+FP32, so now the only thing that changed is that they can do INT+INT too, which as we can see does not do a lot. It started with fake cores, now fake frames...

It might help with certain AI stuff as the whole gpu could now do just int32 all at the same time? else yeah it seems kind if pointless change. I assume a core can do int+int while another core does fp+fp now. vs the same to cores before doing a mixed workload. not sure if that changes much expect scheduling were which OP runs?

Would not be pointless for games if those cores were true FP32+INT as in at the same time for all of them.

Maybe they just lacked transistor budget to do it and it's new foundation for the 60 series...

Not how I read it - each "core" (that consists of FP32/INT) can do either FP32 or INT, but that's it.

5090 listed in Nvidia shop as "Coming Soon", what's the time sale is supposed to start?

Looks like at 2pm UK time

IMO, if that was true
Why would it not be?

4N had 2 years of tweaking, plus frequency is not pushed, so that means binning by it is a lot easier, a fair few bits on chip are disabled too, totally plausible - and yet has no effect on AMD's decision not to compete on high end.

Nvidia GPUs work in a block of 32 "threads", called a warp. (It's more like a SIMD lane than a real thread or core, Nvidia terminology is garbage.) So all 32 "cores" in a warp are executing the same instruction at once, or are masked off and not doing anything.

Ok, so explain this then - why Turin supported FP32 and INT executing at the same time which gave speed up since 1/3 of instructions are INT? That did lead to real observed speed up in games.

IMO, if that was true, AMD would make big die GPU to compete.

Both AMD and NVidia are behaving like the dies are ridiculously expensive at this process level.
You can do the math yourself. Nvidia's wafer cost might be a little higher or lower than the $16000 quoted by the article.

There are other costs. After it's produced it needs binning, packaging, and shipping. Then after it's sold to an AIB partner it needs 32GB of GDDR7, the PCB with all the electronic components, and the heatsink. The partner has their own overhead with customer support, marketing, warranty, sales, and shipping. Then the store takes their own margin.

But even after all those other costs, they're not that expensive. Nvidia has huge margins.

Show me where TSMC advertises this $16000 number...

Can't be ****ed to F5 hoping "coming soon" will turn in to product, Nvidia you can keep it...

Yep this looks like a shitshow, following a few threads of potential buyers, and there were cards listed by scalpers a couple of minutes after the drop, while no one could load a site or even see the buy button on the actual shops.

Will be interesting to see if 5090 remains impossible to get for a long time. Can't believe all microcenters in the US got 233 total

I looked at 9:00:xx and they were all immediately sold out
Saw in Discord Micro Center was allotted 5x 5090 and and 70x 5080 GPUs for sale. What a joke, but I guess that's one way to push folks to buy a 5080. As for me, I'm solidly in the wait for the 6000 series 2-3 years from now and enjoy gaming on my 4090. Maybe I'll just Sharpie 5080 Ti on my 4090 to remind myself what a horrible non-uplift the 5000 series is.

Consolation prize, new driver is out (572.16).

  • DLSS Transformer Model Upgrade - Enables the latest transformer AI model for DLSS Super Resolution, Ray Reconstruction, and DLAA for all GeForce RTX users, when the aforementioned features are ON in-game
  • DLAA & Ultra Performance Modes - Sets the internal rendering resolution for DLSS Super Resolution, enabling DLAA or Ultra Performance mode in games lacking native support, when Super Resolution is ON in-game

It dual issues a vector FP instruction at the same time as a vector INT instruction.
