PCI-E Version Question

Samlikesham · Jul 12, 2014

So my current mobo has pci e 1.0. My gpu (8800gt) is pci e 2.0. So my question is, how much is this holding my gpu back? like i want to play titanfall on it but i think the pci e slot is too slow. Can anyone clarify this for me?

almost all PCI-E graphics cards will work in any PCI-E slot. there are exceptions of course but that is another topic. But in short the performance difference between different PCI-E revisions and 3d performance is marginal. You could put a GTX 680 PCI-E 16x3.0 in a PCI-E16x 1.1 and get very similar gaming performance. The PCI-E uses the Chipset and CPU for Overall Expansion card Bandwidth. You would only notice a hiccup if there were more than the specified amount of Cards; ie: Sound card, raid card, wifi card. ect in the the PCI or PCI-E16x or 4x or 1x slots

You need to upgrade to a board with at least a 2.0 slot.

PCI-e 1.1 vs 2.0 vs 3.0 Technical Demonstration

Probably <2% difference.

A PCIE 1.0 will perform on par with a PCIE 2.0 x8 slot.

IS that your vid?

Here is a correct summary.

Base Clock Speed: PCIe 3.0 = 8.0GHz, PCIe 2.0 = 5.0GHz, PCIe 1.1 = 2.5GHz
Data Rate: PCIe 3.0 = 1000MB/s, PCIe 2.0 = 500MB/s, PCIe 1.1 = 250MB/s
Total Bandwidth: (x16 link): PCIe 3.0 = 32GB/s, PCIe 2.0 = 16GB/s, PCIe 1.1 = 8GB/s
Data Transfer Rate: PCIe 3.0 = 8.0GT/s, PCIe 2.0= 5.0GT/s, PCIe 1.1 = 2.5GT/s

It's more than 2%. ^

I can't speak for anyone else But Thanks for the info. )

EDITED I have seen this chart before I can't find the original article but basically in Single GPU mode the difference is within margin of error. It only makes sense as you use up more lanes in a SLI or Crossfire Setup.....http://www.techpowerup.com/reviews/Intel/Ivy_Bridge_PCI-Express_Scaling/6.html..This is the right one

No, it's not mine. I just did a quick Google search and found it, LOL.
