PCIE 1.1 vs 2.0 graphics benchmark performance question.

post #1 of 3
Thread Starter 
I've got a GTX560 Ti in PCIE 1.1 x16 slot in an old AM2 platform with a Phenom x4 9650, and PC800 DDR2 RAM.

It is a dedicated folding rig, so I don't actually care about its gaming performance, or overall benchmark scores, but I am curious about something.

With the card in that platform, would the graphics score in 3DMark11 be significantly lower than if the card were in a PCIE 2.0 slot in a x58 platform with an i7-950 and associated hardware?
If so, any guess as to roughly how much of a difference?

I'm just wondering about the graphics part of the score, obviously there would be a massive difference in the combined score.

I'd just swap it to the better system to test it, but both systems are water cooled, so it would be a bit of a PITA.

For 560 Ti, PCIe 1.0 is enough. Only when you get to GTX 580/590 where a slight difference should show.

Well, it is running 1065mhz core clock, so it keeps pace with 580's folding performance...

One other oddity, the graphics part of the score in 3DMark is higher when the CPU is folding on all 4 cores at 100% load than it is when the CPU is idle, by a significant amount.
The combined score doesn't even attain the level of "laughable" though.
