[TH] $5K PC Takes On $4.6M Supercomputer - Page 4

post #31 of 41
Enough with the intel quad with SLI would have done it better.
THE USE OF AN INTEL CHIP would have made it so only 3 9800Gx2s could be used, also, these cards are not SLIed, they are running independently to do calculations, not render and process games. The focus here is on GPGPU processing, to the choice of the phenom allowed for more GPUs to be used, which was the point of the comparison in the article:

general purpose GPUs against a super computer.

My goodness thank you! It really makes a lot of sense. SLi is absolutely pointless with this kind of work. While a CPU is very good at a lot of different things, a GPU is REALLY good at doing one thing. For raw number-crunching, it makes sense to have an array of powerful GPUs which then are governed by a CPU. Remarkable really when you think of the raw computing power this thing has when utilized in a way we don't normally think of.

Complaining about SLi and 3DMark scores is about as useless here as complaining about the towing capacity of a Ferrari Enzo.

This justifies why people need big budgets.

We'll see the results with 4 GT280 lol! And for real, get rid of that Phenom, a QX6950 would be better or even a cheaper Q6700 FTW!

EDIT: how do you know that the latest Intel chipsets wouldn't support 4 GPUs?

Have you not read the thread at all?

The cpu is pretty irrelevant. This is all about the raw processing power of the gpu's. Simple as that. No sli or anything is needed since they are not producing a video output like in a game. The cpu is sending them calculations to perform and they do it.

Also it has been pointed out in various news threads that the GT280 because of low clocks has failed to break the peak single-precision floating point performance of 1 TFLOPS. It falls under. That means a 3870x2 would actually be better in this application than a GT280. It depends however what kind of calculations this program is running to understand which gpu is best.

The chipset used here could have been chosen for compatiblity with their software.

$5,000 PC : " well , you still have more ram than I do? ,dont take it soo hard on yourself , all computers get outdated eventually....."

$Super computer : " yes..but not after 24 months!!!........I remember the good old days...when they put me together , i was marveled at , I could do a super PI score of 5 seconds!!! i was the king at that!!! I could run Half life 2 on maximum settings withought blinking an eye!, I was the most powerfull computer in the world!!!! now i cant even run Crysis!!*sniff*...now......now iv....iv have been dethroned by you!!!.....*sniff*...i think im catching a cold...or a virus!! *cry* , guess my end is near..........goodbye cruel world!!"

$5,000 PC " I know...I know....."
That made me feel sad as well...
