Benching: GTX580 Direct CU 2 SLI first results

post #1 of 15
Thread Starter 
Ok people... so yesterday afternoon me and a friend were taking a coffee and decided doing some benchmark ... He was thinking about changing his 2 GTX570's for a GTX580... and yesterday after checking the GTX580 DCU2 he went for it.

So we dedided doing a little GTX580 DCU2 SLI benchmark.

These benches suck because, we were using a a system that had 2x470's and didn't reinstall a thing... and it's not a clean install.

Again, we had no cameras to take photos ( just an iphone ) and since this was nothing really serious we just try out benchmarks and didn't take real pictures of GPU-Z and stuff.




Test System:

Xeon W3520 4Ghz HT On
6Gb GSkill DDR3 1600 Cas6
2 x Asus GTX580 Direct CU 2
Silverstone Strider 1000W
Physx was on Auto, thus the high cpu results

Heaven 2.1 stock clocks



3DMark 2010 stock:



3DMark 2010 @ 940 core ( 1.11v ):



3DMark 2010 @ 960 core ( 1.13v):



3DMark 2010 @ 973Mhz core (1.15v):



3DMark 2010 Extreme, Ansio @ 16x, Multisample count @ 4, 1920x1080, stock clocks



at stock clocks we never saw power consumption above 560Watts @ full load.
With overclocked GPU's we got some whooping 761 Wats @ full load. 200W more than stock clocks. Amazing power consumption increase with 1.15v at core.

I must say... the cooling of these babies is just plain AMAZING. We never hit 70ºC even @ 976Mhz with 1.15v. We forced 100% fan, but i must admit i was prepared to see higher tems

Next week we're going to clean install a Sandy bridge @ 5.2Ghz and get new bios into the boards to try and reach the 1Ghz. I feel that we need a clean install to make this bad guys work full potential without any residual drivers and files in the system.

Nice little write up. +1

EDIT:
You should run the benchmarks with a single card to show how well it does/doesn't scale in SLI.

Yes... we are going to do that... and a more extended benchmark analysis. This was a decision that we did in ... 5 minutos

I had my 580 and he got his 580 so we just did a SLI and test it!

Next week we'll do some Single & SLI benchmark

Oh... and until some waterblocks are available for these babies... i can't install a SLI of them in my case

Since i have a Creative Titanium HD ... i don't have space for 2 of these and titanium ... the coolers will block the PCIE 1x slots

You should run 3DMark 11, the basic version is free.

Bio, yea
We bought the Vantage and the 2011 yesterday after thinking about doing something more serious

So our plans is:

Run Single GTX580 @ cpu stock and gpu stock
Run Single GTX580 @ cpu stock and gpu clocked
Run Single GTX580 @ cpu clocked and gpu stock
Run Single GTX580 @ cpu clocked and gpu clocked

Do the same tests for SLI.
We want to discover the scalability of all the system.
We'll also do a X58 and Sandybridge testing... Just to understand, under the same ambient, what's the differences in performance between both using these cards.

Benchmarks
3DMark Vantage
3DMark 2011
Heaven 2.1

Tell me more benches that you would like to see

I'm not really looking at getting GTX 580's, so I'm not really that interested, but an ingame bench is always a good idea. I'd recommend Crysis, Metro, Far Cry 2 or F1 2010/Dirt 2. The Crysis demo is free and can be used with the benchmarking tool, so if you don't own any of those games, you can get that demo. Don't do it for me though.

Ok
I'll try to get the max i can from the games i have and the demos i can download

It would be nice if you can record the wattage consumed for each test, making your tests more comprehensive.

And, which motherboard will be used for these tests?
