GTX 580 8x vs 16x...

post #1 of 7
Thread Starter 
So I just removed my PhysX card which allowed my GTX 580 to get full 16X PCIE lanes all to itself an my Heaven 2.1 benchmark jumped from 869 points to 893

Pretty significant I think.

Did you do 3 tests and then record the average, that would be a better way to determine the actual advantage,

As often bench-scores differ somewhat when testing, so getting an average is a reliable method.

How I test Heaven is I let the thing do a full loop on its own, an then run the benchmark allowing textures to load etc. think that gives the best results

I don't really sure how you see that as significant.
Its 2.7% improvement, which is pretty much what you would expect.

Also, running three 3dmark tests one after another, can give differences between the tests from 200 to 800 points on the exact same settings.
Same with heaven benchmarks.
You can do a loop, run the bencmark, restart, do the same, get 870 points instead.

To get real results, do a 3 run average.

Also, a better measure, is the hwbot.org heaven test. The scoring is different and better imo than just running heaven.
