Is the PCI-E 3.0 standard compatible with the PCI-E 2.0 standard? My newly upgraded motherboard and processor still use the original graphics card. The new motherboard only has the PCI-E 3.0 graphics card slot. The graphics card is PCI-E 2.0. I want to know if it is compatible with each otherView All
PCI-E 3.0 is compatible with PCI-E1. x and PCI-E2. x devices, and also supports 2.5GHz and 5GHz operating frequencies. PCI-E 2.0 graphics cards can be used normally on PCI-E 3.0 motherboards, and generally there is no difference in support between PCI-E 2.0 and the old motherboards.
PCI-E 3.0 is mainly to remove the 8b/10b encoding mechanism, so as to avoid the waste of 20% of the original transmission rate. Therefore, the transmission bandwidth can be doubled again on the basis of PCI-E 2.0, reaching an astonishing 8GT/s.In addition, PCI-E 3.0 will also optimize the enhanced signal and data integrity in many aspects, including transmission and reception equality, PLL improvement, clock data recovery, channel enhancement, and so on.
It is better for SLI and CF components to improve the transmission speed.
