Wrong GPU Species on Titan X (Pascal) in GPUs.txt

[Shirty]

I've just noticed an issue with my Titan X machine, in that it's showing as a species 6 GPU in GPUS.txt, where it should definitely be a species 8:

0x10de:0x1b00:2:6:GP102 [TITAN X] 6144

Here is the GPU-z sccreenshot:



This card is a fair bit more potent than the 1080Ti for folding (more akin to an RTX 2070), so it seems a shame that it might get left behind when work is assigned!

It's currently making approximately 1.75M ppd on P11741.

A RTX 2080ti can do double the work than a gtx 1080ti. So Titan X similar to gtx 1080ti cannot get the highest GPU species. Also I understand highest GPU species the way that it needs biggest GPU work units to get fully utilized. gtx 1080ti or Titan X is also fully used with smaller work units.

Species changed to 8 to match with 1080 Ti and Titan Xp species.

Many thanks toTow.

@foldy, I don't disagree that the 2080Ti is in the lead by some margin, but high end cards from both this and the previous generation can all turn in the most complex work units very quickly and see a notable increase in output when running them.

There were also some high end nVidia cards that did not go to the higher species classification when they were created because testers found they did not scale as well on folding. Don't recall if the Titan X was one of those.

If it helps, from my testing on 1000s of work units across multiple high-end Nvidia cards (both CORE21 and CORE22), I'd say that the ascending order of PPD is:

RTX 2060
GTX 1080Ti
RTX 2070
Titan X (Pascal)
RTX 2070 Super/RTX 2080
Titan XP/RTX 2080 Super
RTX 2080Ti
