The Chinese HKEPC website released some benchmark results and screenshots of the ATI RV380 card and the Geforce FX 5200 using PCI Express. First they talked about the PCI Express and used a lot of screenshots.

The next generation of AGP comes in different versions, x1 to x32. x1 is the slowest and uses a speed of 250MB/s, to compare the speeds of other PCI Express cards they simply multiply 250MB with x(number).
