Workunit batch: ADRIA_BanditGPCR_APJ_b1
OS: Ubuntu 18.04.6
No CPU tasks
CPU is a Core i3-9300 @ 4.1GHz
Motherboars is an MSI B360M Mortar
RAM is a Kingston Predator 2400MHz 12-14-14-29 @1.35V in dual channel
RTX 3080 Ti is a Founders Edition driver 495.44
RTX 2080 Ti is an MSI GAMING X Trio driver 495.44 (in a different motherboard...)
Ambient temp is 26-27°C
There's no correlation between the runtimes and the CUDA version, so the CUDA 11 app is not slower on older cards than the CUDA 10 app.

| -------------- RTX 3080 Ti ------------- | ----- RTX 2080 Ti ------ | power | boost | | speed | power | GPU | boost | | GPU | limit | clock | runtime | incr. | incr. | temp | clock | runtime | temp | 350W | 1815MHz | 17.347s | 32.0% | 36%* | 71°C | | | | 300W | 1710MHz | 17.961s | 27.5% | 20% | 67°C | 1860MHz | not yet | 71°C | 250W | 1575MHz | 19.176s | 19.4% | 0% | 63°C | 1800MHz | 22.900s | 68°C |
* the actual power draw was "only" 340W, so the increase is only 36%, not 40% to be fair
The base for the speed increase calcualtion is the RTX 2080 Ti @ 250W.
The RTX 3080 Ti founders edition has remarkably good cooling, provided that you will use only one in a single PC.
I will to put the GTX 1080 Ti into the comparison, but I decided to postpone it after this expired certificate issue is solved.
I have a feeling that the improvement of the RTX 3080 Ti over the RTX 2080 Ti is much less than the improvement of the RTX 2080 Ti over the GTX 1080 Ti, or is it just the bonus system of folding@home playing with my mind?

I leave my 3080Ti set to 300W. It's a nice balance between power and performance in my opinion.
