Other Cards In PCI-E Slots Intended For GPUs?

post #1 of 9
Thread Starter 
Are there any gains to be had by connecting things like sound cards and NICs to the PCI-E lanes coming straight off the CPU? Usually we connect GPUs to those lanes and then other cards are connected via the chipset. Is there any difference in latency?

I know with p67/z68/z77 populating more than one of those slots will make the GPU operate at 8x, but depending on the GPU this may not be an issue and it's a non-issue for the enthusiast platforms.

Thats an interesting question, the only thing I have to add is that some NICs require a PCI-E 1x slot; and im not sure why. But im posting to increase attention to your question.

none whatsoever, If I remember rightly there was an issue with PCI-E Sound cards having a lag or something because there was too much bandwidth, they might have sorted that out.

As for NIC's no, there is no benefit at all of using a PCI-E card, can you even get them?

Can you reiterate what you were trying to say in this line, I don't think I'm understanding you correctly.

And just to clarify, I'm only talking about latency, not bandwidth.

Ok if there is a difference in latency it won't be noticable. Ergo no point really in getting PCI-E cards when the onboard stuff will do it just as well.

Sound cards are still better on a standard PCI port unless they sorted out the issue with the PCI-E cards.

I cannot agree with that at all.

I'm not sure what 'issue' you're referring to with PCI-E sound cards, and I'd sooner have a native PCI-E sound card on a PCI-E slot. PCI cards will be going through a PCI-E to PCI bridge chip.

I'm talking about network cards with the onboard comment,

Also it was only the nforce chipset that had the issue with PCI-E sound cards so ignore that as well.
