PCI 3 Question.

[ljtatej]

Wasn't sure where to put this because of all the factors, but will we see any improvement over PCI 2 with the new upcoming cards with IB?

No, only 4GB/sec of bandwidth is required (PCI-E v2.0 x8), so going from 8GB/sec to 16GB/sec makes no difference.

I'm pretty sure when they start to benchmark the new cards on PCI-E 2.0 slots and now new PCI-E 3.0 slots you will see a similar performance difference as what we saw between PCI-E 1.0 and PCI-E 2.0, which is around 3-5%, at most.

not really.

Yeap.... PCI 2 is fast "enough" for now.

The new cards might use more memory bandwidth than existing cards, leaning more on the PCI-E 3 bandwidth. The the new shared memory model for GPU compute for example is likely to benefit quite considerably when the data set is larger than 3GB. Its unlikely that the additional bandwidth will be required for gaming based on what we know but there could be a sizeable difference in some circumstances.

just saying
I guess we need to wait on some benches with 2 x 590's now[ & 2x690's later] + pci-e sound card + raid card on a sb[native no nv chip] vs a x79 with the same load out running surround at +5xxx res. - then with a pci-e 3.0 system down the road

-any of the pci-e 2.0 x8 vs x16 benches , showing no driff. seem like they set up a system to show no difference. never seem to use the other pic-e cards. or at high res.

-meaning I have lets say I have a sb system 2 x590 [[no nv chip ]+sc + raid card ,3 x 1920x1200 monitors and it will run @ full speed [same fps] yes or no.

PCI-e 3.0 is one of those things that is nice to have but not important enough to affect the timing of your purchase/upgrade. The holy trinity is still GPU, CPU, and ram.

Be useful if Turbocache/Hypermemory made a comeback. A 16x PCIe3 slot has more bandwidth than 64bit memory video cards.
