I bought 2 GTX570 for my Linux server and it takes 785s (@Stock) to perform 1 WU of 4,523

Any GTX560 ?

I know it is difficult right now to do some comparison, but we need all of us to give our data based on same app/type of WU.

Thank you for your participation.

Hi there,

Sorry for not having replied earlier. Been busy during this Chinese New Year.

So based on your latest info, here is what I got:


However, it would be nice to improve the reliability of these number and also improve the scope.

Hence, I'm asking you to check these value if you have such a card.

Also, if you can give me more info about your cards, new cards, etc...it would be perfect, being based on the latest PPS app.

I might prefer that you use this format (but anyway, it is already kind that you provide me your numbers)

Graphic_card_name - Freq - time
(as some of you already did)

Thank you guys !

I wonder if some1 put the hands on 560. My buddy asking if he can save couple of $$ taking 560 instead of 570. Me personally do not think so though.


Indeed, it would be interesting to see the performance of this card !

Thanks for all your message.
Scott, your suggestions are more than welcome.

So I will modify my table later to add new spec.

What I did so far was to take the GTX/GTS 4xx and 5xx and to also check the price of these, in order to find the best perf/price.

For ATI, it is clear that Nvidia beat them (that's why I took only the latest Nvidia version)

Here is the table (Simple Excel table)


What you can see is that unsurprisingly the model GTX 480/580, because of their price, have not a good perf/value.

But globally, based on this table, I think a GTX570 is a good value for those who want points and evolutivity.

Note that my prices are in euros, based on the french price comparison website "i-comparateur". And that the UT duration is based on the Windows app.

Don't know if it's worthy to do the same with other Nvidia cards, or ATI cards.

I've realised that there isn't any topic to compare and centralised the "Crunching Power" of our graphic gards under Primegrid !

So in order to simplify the choice of GPU when buying a new graphic card, I suggest to post our results here in term of points.

I start with my numbers and some from my team members

PPS Sieve:
Ubuntu: ATI 5870@Stock: Average: 1 370s per task - 2 311pts - 6 073 pts/h - 145 700 pts/day
Gentoo: ATI 5870@Stock? : 1 050s per task - 2 311pts - 7 923 pts/h - 190 200 pts/day

Gentoo: Nvidia GTX580@Stock: 400s - 2311 pts - 20 800 pts/h - 499 200 pts/day

Windows 7 64b: ATI5970@Stock? : 1 150s per task - 2 311pts - 7 230 pts/h - 173 600 pts/day X2

And you ?

NB: Later, I will do a table to get a better comparisan, based on our results.

Ubuntu 10.10 64b with an ATI 5870 gives me 17mn per task.

Cross Fire doesn't seem quite good for now...I got a GPU usage of 40-50% for my 2 5870.
Anyone else tried ?

Thank you mfl0p !
Nice to see this update !
So something like 15% - 20% improvement so far ?

I might try this week with my GTX275 and compare both version.
