Nvidia Post-Volta (Ampere?) Rumor and Speculation Thread

Current gaming RT implementations are not limited by RT core performance or capabilities, as can be seen from performance comparisons between gaming RT gains on h/w with RT cores against gains on the same h/w in professional RT applications. Thus there really is no reason to improve RT cores specifically, without improving the rest of gaming / hybrid RT pipeline - unless you're only aiming at professional rendering niches or fully path traced games like Q2RTX and Minecraft RTX - which I'm fairly sure will be in the minority during the whole next gen console h/w cycle.

 

I'm more worried about performance pitfalls due use of Cuda cores in cases in which might be better if RT core could handle it by itself.

Currently instancing seems to be limited to single layer before needing to use Cuda cores during tracing etc..

Hybrid pipelines will be the way forward for now and any flexibility that allows RT part not swamping rest of the GPU should be good.

 

Could you get the stated performance increase (70-75%) in Indiana's Big Red 200 if Ampere were in fact at 10nm instead of 7nm?

GA100 supposely is on 7nm but the gaming GPU's (GA102... are not)

 

The nice thing is you can also post made up stuff on twitter and make GA102 anything you want it to be!

 

This didn't age well. XSX supports Machine Learning through RDNA2 CUs now, which means AI upscaling will be a real thing at least on Xbox. Which means this will be thriving very well on PC.

 

Assuming anyone creates an AI upscaling system (that doesn't violate any Nvidia patents) on Xbox and it's actually used by developers.

 

Remains to be seen. Using GP SIMDs for AI upscaling can be both not fast enough and not make much sense as this way you're taking away the computational power from actual rendering.

 

DLSS is post-processing. So it has the same limitations.

Microsoft said that the Xbox Series X would need additional 13TFLOPs to archive the same performance with RT. Doesnt sound that RDNA2 is even close to Turing's RT Cores (nVidia said that RT Cores are 10x faster than using the shader cores)...

 

For the BVH stage, not overall RT performance.

For me it sounds for the whole "hardware acceleration" part. But english is not my native language.

 

Yeah you might be right but could be misinterpretation from the source context as well. Could very well be true.

 

Nvidia Postpones GPU Technology Conference News: Ampere Will Have to Wait

Yes, it's for the "whole hardware acceleration part", but NVIDIAs 10x isn't.

 

nVidia claims it:

ML memes take many forms, shoddy upscaling is but one of them.

 

This pretty much confirm the postponed news is the announcement of HPC chips.

Yes, but you can bet AI upscaling will take center stage, especially to mitigate the impact of RT.

 

Eh, nah.
VRS tier2 will be the snazz, though.

 

Doubt. VRS + TRAA is far more likely for console h/w.

 

I doubt they will be able to do upscaling in a classical sense due to at least 10 bit precision requirements for HDR rendering. 8 or 4 bit ints can be used only for some very specific things in graphics, which can tolerate such low precision.
