So I got tired of ray tracing taking forever and picked up a pair of Tesla cards. Figured I would give them a run at Agisoft and share some informaiton on them:
Nvidia Tesla M2090
6GB DDR5
225W TDP
Average power usage with Agisoft 150-180w
Idle power usage 20-30w
Idle temps 30-47C
Average temps under load 70-90C (passive cooling right now)
ECC Memory State turned ON
I am getting a lot of throttling use to temps right now, the case was not designed for passive cooling co-processors. I have a few ideas I will be testing out this weekend to try adn get the load temps to under 70C all the time. Ocne I do I will run the tests again. After multiples tests with the Agisoft benchmark data I got the following average samples/sec
Medium Reconstruction 500-600 million samples/sec
I think I might be able to squeeze a little more out of the cards by turning off ECC memory state, which will raise the memory bandwith. I will test this out tomorrow after I work on getting the cards cooler.
All in all I am very happy with these cards and their performance. They are under permorning the $300 GTX 780 cards I have, but at the price poitn I got them for, $75 each, they are simply amazing.
Just wanted to share since there has been a few other interested in Tesla/Phi chard performance. Check back later this weekend for more results
