1. Raytracing denoise pass is done via compute, read my post.
No, it's performed using the Tensor cores, not the shaders.
2. PC DirectSTorage decompression is done via GpGPU compute. Try again.
Try what? What does decompression have to do with GPU performance? CPU decompression is still way faster than GPU decompression. So who cares.
3. My post answered the Ampere RT vs RDNA 2 RT question. Follow the thread.
Fine. Not sure where the RT question came into play, because you and I were talking about Ampere's FP compute being largely useless in gaming workloads.
4. Ampere Compute TFLOPS is real via a certain path.
Of course it's real. If you can fill all the ALUs you can get lot of compute performance. That 'certain path' just isn't games. Most people here don't care about compute workloads. And even if you did, you'd probably prefer getting RTX A6000 instead of a 3090 because it would have pro drivers that fully extract Amperes compute capabilities.
5. PC DirectStorage decompression function is done via GpGPU path. DirectML is another GpGPU path.
Cool. So what?
Nvidia will use their tensor cores for ML, because they're faster at matrix and bfloat operations than cuda cores or regular vector ALUs.
6. Wrong. PC and XSX RDNA 2 was modified to follow DirectX12U and Vulkan counterpart. I answered the question
Modified how? Do you have the white papers for RDNA2 and Series X's ISA to be able to confirm that DX12U features enabled on XSX doesn't exist in PC RDNA2? I want to see the receipts. You can't make a spurious claim here and have no evidence.
7. Unlike the RDNA 2 competition, RTX 2080 Ti has a separate TIOPS resource that hides extra performance from the typical TFLOPS debate.
This sentence is unintelligible. What are you talking about? TIOPS 'hide' extra performance? What is being 'hidden' and how? This sentence makes absolutely no sense whatsoever.
NVIDIA debuted its Turing graphics architecture today, straightaway with the flagship RTX 2080 Ti. This card packs the promise of real-time ray tracing at 4K UHD, besides huge gains in performance. NVIDIA also put out its best cooler design since TITAN, commanding a very high price for some very...
RTX 2080 Ti FE real-life average clock speed is higher than paper spec i.e. 1824 Mhz (~15.9 TFLOPS
, not including partly used TIOPS)
It's still 40% slower than Navi 21 so who cares how many TeraFLOPS it has. Not sure what relevance Turing and it's compute performance has on a conversation about Ampere and Navi 21.
