RTX 3080 Ti BOINC Performance

[Jason Jung]

I was lucky enough to get my hands on a RTX 3080 Ti; specifically the Gigabyte GV-N308TAORUS M-12GD. After running tasks for various projects here is the estimated points per day:

Project	Sub-Project/App	Single Task PPD	Dual Tasks PPD
Primegrid​	PPS Sieve	4,045,200	4,936,515
Primegrid	Genefer 17 Mega	358,529	374,826
Primegrid	WW	3,676,595
Primegrid	AP27	1,525,393
Einstein	hsgamma_FGRPB1G	1,360,800	Computation Errors
Milkyway	Milkyway	218,419	302,413
Collatz	collatz_sieve	8,132,791	16,265,583

If anyone wants me to test out another project for comparison let me know.

Going off memory that looks about double the 2080 Ti. I'm not paying double the price to get one though.

That video card would do extremely well at Folding@home.

If GPUGRID doesn't have consistent work in the fall I'll probably do Folding@home again.

Without much happening this week I thought I'd play around with MSI Afterburner. Most of the time my 3080 Ti is power limited. Seems to be the main limiting factor for this generation of cards from Nvidia. What I've landed on saves quite a bit of power and gets similar performance to stock. Slightly better in the Time Spy and Port Royal benchmarks but slightly worse in Fire Strike.

Stock core clock curve goes up to 2010 MHz at 1075 mV.


I've set the core clock to -75 then adjusted the curve at 925 mV up to 1905 MHz (+60). +500 MHz memory clock. 100% power limit.

Project	Stock PPD	Power Usage	OC PPD	OC Power Usage
PrimeGrid - Genefer 17 Mega	358,529	349W	344,107	243W
PrimeGrid - WW	3,676,595	397W	3,770,181	343W
Einstein x2	3,070,523*	388W	3,039,350*	297W

* Einstein has a quota of 680 tasks per day per GPU, or something like that, so you can't actually reach these numbers until they raise the limit.

Amazing! I was reading a little about the upcoming 40xx cards and while performance is expected to be off the charts, power consumption is a major concern. Hopefully tricks like this will help.
