What is the difference between 8x and 16x pcie

We switched between the first x16 slot and the first x8 slot for these numbers, then validated in BIOS and software. We tested using our GPU test bench, detailed in the table below. Our thanks to supporting hardware vendors for supplying some of the test components.

NVidia's Game settings were manually controlled for the DUT. All games were run at presets defined in their respective charts. All other game settings are defined in respective game benchmarks , which we publish separately from GPU reviews. Our test courses, in the event manual testing is executed, are also uploaded within that content. This allows others to replicate our results by studying our bench courses. Each game was tested for 30 seconds in an identical scenario, then repeated multiple times for parity.

We do not measure maximum or minimum FPS results as we consider these numbers to be pure outliers. For Dx12 and Vulkan API testing, we use built-in benchmark tools and rely upon log generation for our metrics.

That data is reported at the engine level. Let's just post all the charts first, then talk numbers — they're similar enough that this is the easiest way to read the data. For Shadow of Mordor, the numbers are similar — we're seeing a 0. These numbers are close enough in some instances — like the GTA V If you wish to find exactly which lane is which, I would advise looking in your motherboard manual. There will actually, in your case at least be little to no difference between which lane you put your card in, providing it is not the 1x slot.

Return to Level1Techs. Hardware Motherboards. There is no physical difference between the two, except for the pins inside the plastic part. In your case; you have the following lane speeds: 3 x PCIe 2. I would gladly bet that they're running an athlon. Only in some games but its bound to get worse in the future.

Usually wrong games are being tested which is why it still has myth status. Very easy to see on their first game in the video Rise of the tomb raider, almost no difference. Battlefield 1 and witcher 3 whole different story. I did a fresh install of a driver and forgot to do force enable pcie 3 x16 on my x79 k.

So they were running my sli ti's on pcie 2 x I was benching 4k and thought something was wrong. It definitely makes a difference at 4k sli I Think it's a minimum requirement now or should be for 4k sli ti's. Faster IPC and higher clock - 4. I have a Core i7 k at 4. The motherboard crapped out on me and was out of warranty.

RMA'd it, had problems with that one. Great board on paper, not so much when putting it together. Incredibly stupid thing. The m. The k has 40 lanes, and they are taking them from the second slot instead of one of the bottom ones like MSI did.

Anyway, I actually had it set up at first with the CPU in the first, and the second card in the 4th slot for more space, better cooling. That set up ran them both in 8x mode. Everyone always said that was enough, but I noticed it seemed more 'hick-up-ie' I know, not a word, but pretty sure you all know what I mean.

Right away there was a difference. I could have done a bunch more benchmarks, but I googled it and found some of the videos posted above where it does show it makes a difference, sometimes huge in some games.

Which makes me wonder, what about with the new RTX ti cards? They also have the new NVlink, so maybe it won't matter as much? Black Friday is coming up, and I was sort of wish listing the new k benchmarks out today, just started reading them , but it's limited to the 16x PCIe lanes really stupid for Intel to be doing that to begin with, especially with all the m.

Now I'm trying to see if I can bypass that and get the X instead. Definitely staying away from Asus this time though. Made an account just to reply I bought the Asus WS z Pro and it arrived today Ofc the pcie lanes matter - how much depends on the game, as some use a whole lot more bandwidth than others.
