Speaking at a recent press conference, PCI -SIG chairman Al Yanes disclosed some additional details regarding the upcoming connector. Not only he confirmed that PCIe 3.0 offer data throughput at 8 gigatransfers per second, but also that the new specification is needed to support future three-slot, 300-watt graphics cards.
The good news for anyone considering a big component upgrade over the next few years is that PCI Express 3.0 will use the same connector and will be backwards-compatible with 2.0, the only difference should be in the electrical specifications. PCI-SIG expects to complete the PCIe 3.0 spec in late 2009, and it plans to begin testing in the second half of 2010.
