P67 PCI-E version?

[Spooony]

I notice on a review that they mention the Pci-e version is 3.0. But in INTELS whitepaper they stated its Pci-e 2.0 version 2. Can anyone clear this up?

If there were any PCI-E 3.0 motherboards out, it would be a megathread in this forum. PCI-E 2.1 (which may be the version 2 you are thinking about, if PCI-E 2.0 is considered version 1 of PCI-E 2) was quietly rolled out on some motherboards; 2.1 has most of the features of 3.0 except the increased speed, but these features are of little interest to consumers (power management and troubleshooting and the like).

Doesn't really matter anyway. The fastest video cards out now are barely able to saturate PCI-E 1.0, and it's an open question of whether there will ever be a video card that saturates PCI-E 2.0, which has twice the bandwidth of 1.0. PCI-E 3.0 doubles the bandwidth again, but that extra speed will probably never be used.

Actually Pci-e 2.1 intel calls Pci-e 2 version one. So version two is 2.2. Pci-e 3.0 the overhead is going to be reduced. Actually its not the bandwidth is not able to fill its just the overheads too much once going faster that's why we were stuck on 2 so long. Latency was its enemy and it only had a 70 percent efficiency which means only 70 percent of the data sent to the other side reaches it.

But that's not the question

Here's a piece from the review

P67 natively has 8 lanes of 5GT/S PCI-E 3.0 which goes into 16 lanes of 2.5GT/s PCI-E 2.0 which X58 has 36 lanes of PCI-E 2.0.

Here's the review

sin0822 has a typo in his review. PCI Express 2.0 supports both 2.5GT/s and 5GT/s signaling rates whereas 3.0 is 8.0GT/s.

PCIe 3.0 won't be implemented until LGA2011.
