GTX480 PhysX very interesting results...

post #1 of 6
Thread Starter 
I have a GTX480 with a GTS240 (higher clocked OEM version of 9800GT) being used for PhysX. I wanted to see how much faster games with PhysX run while using the dedicated GTS240 for PhysX versus doing it on the GTX480. So I downloaded the Cryostasis Tech Demo and got some very interesting results.

With the GTX480 plus the GTS240, the result was:


And when using only the GTX480 the result was:


It seems there is only a slight increase in performance when using a dedicated card for PhysX with the GTX400 cards. With GTX200 cards and below, the boost from a dedicated PhysX card was much more drastic.

I don't know much about the test game you used, but does that game take advantage of PhysX? I'm definitely not an expert on the subject, but I was under the impression that only games that were designed to take advantage of PhysX would show any difference. Similar to Multi-Core processing in a way.

Well,

If you have a look and do the math you're seeing more than a 10% increase in FPS. Which is perfectly fine if you have a spare GTS250 sitting around. Don't get me wrong, the GTX480 is more than capable of dealing with physx as well as standard processing. But a 10% increase for FPS is pretty respectable.

When looking at PhysX results, focus on the average FPS. 36 to 41 is very good for such a little card.

I had similar results in Batman. 8% increase on the 470 vs 52% on a GTX275.

Useful info!

I know one of my 8800GTX will come in handy when my Fermi comes.
