 We remove 1Gb/s for protocol overhead and error corrections. The main difference between the generations besides the supported speed is the encoding overhead of the packet. For generations 1 and 2, each packet sent on the PCIe has 20% PCIe headers overhead. This was improved in generation 3, where the overhead was reduced to 1.5% (2/130) - see [[https://en.wikipedia.org/wiki/8b/10b_encoding][8b/10b encoding]] and [[https://en.wikipedia.org/wiki/64b/66b_encoding][128b/130b encoding]].
