Well, everything’s in the title…. I have 2 of both cards in my setup, ran the exact same simulation twice on each card, so 8 runs in total :
1080ti : 44min and 52secs (average, one of the cards is primary display)
2080ti : 43min and 18secs (average, computing cards)
It is also worth mentioning that GPU load during the simulation is quite low, 15-20% on average on the 1080ti, rarely peaking around 45%, 11-14% on the 2080, didn’t see it peak past 20%.
Is this underexploitation normal ? I mean, in the TFD optimization guideline I read it is advised to have 2 gpus, a weaker one as primary display and a stronger one for computing…… this does make sense in a gpu renderer…. for instance, I use redshift and in some scenes the rendertimes are actually smaller when I do NOT use my primary display card for rendering. However, with TFD only using 10-20% of the card…… I tried using my display 1080ti and my computing 2080ti and got almost no difference.
I plan on swapping my 2nd (computing) 1080ti for a 3090 (when they are available again), this sure will help with redshift but…. from the looks of it i suspect this won’t help TFD in any way other than increased VRAM
For the records, I’m using :
last TFD version v1-0_1465
up-to-date Nvidia Studio drivers 461.40
