Source : ExtremeTechWhile the current second evolution of PCI Express just started to arrive on our motherboard, we are already hearing about its successor, aka PCI Express 3.0.
As usual, this new evolution will double transfer speed to 500 Mo/s per lane, so a 16x channel PCI Express 3.0 could deliver up to 8 GB/s. In order to think of the growing requirement of energy of our graphic cards, the new specification will allow 300-watt power supply while providing three-slot of dedicated space for giving enough room to install huge cooling system on those hot GPU.
PCI Express 3.0 will be backwards-compatible with PCI Express 2.0 as the connector will remain the same, only the electrical specifications should be different. The first motherboard to feature such PCIe 3.0 slot should hit the market in H2 2010.
