Sure, I took 15% out of total 47%, that's (7 ms/47)*15 = 2.23 ms in my calculationsi could use the same math and come to a different conclusion
That's the issue, without knowing test scene, settings, etc, we can not compare these results with Turing ones.but he has 80 fps average on his TitanV (not knowing what level and such...)
I remember there were press drivers with enabled RTX on GTX 1080 Ti (or was it the fallback layer?), the difference was drastic - https://www.ixbt.com/img/x780x600/r30/00/02/11/02/swreflectionsdemo.png
Pretty sure Volta would still lag at least 2x in heavy regimes
There is a power wall, it would be problematic to achieve more flops with more shader cores on the same tech process, GV100 is way wider, yet it achieves less flops than high end TU102 SKUs because both chips are power limitedCan it be that fixed function RT core is not worth it and they would have achieved the same with more shader cores instead?
Pretty sure more general SMs would cost way more transistors, frequencies would be lower because of the mentioned power limitation and even with special SM instructions to accellerate ray-triangle intersection tests, it would still be much slower in RTX games. C'mon, NVIDIA has been working on optix for a decade, do you really think they cannot model and calculate such simple things? Give a little bit of credit to them.
Nope - https://www.ixbt.com/img/r30/00/02/14/58/swreflectionsdemo.pngAccording to this 2070 is only slightly faster than 1080Ti IIRC
