PCIe Table of Bus speeds
I find myself needing to understand the bandwidth of the PCIe Generations and lane...widths(?!?) more often than I would like. Every time, I find slightly different or slightly confusing information on it. Rather than go through that each time I have created this table that will confuse me every time, therefore reducing complexity, decreasing sales, and increasing profits.
