		dragontamer on June 26, 2018 \| parent \| context \| favorite \| on: AMD Tackles Coming “Chiplet” Revolution With New C... PCIe 2.0, USB 2.0, SATA / AHCI, and more protocols are 8b/10b. So all of these protocols were 10-bits per byte. Modern protocols tend to be 64b/66b or better. So that's why I listed "assuming 8b/10b", its hard to memorize which protocols are which. Apparently I'm wrong. 10G Ethernet seems to be a more modern 64b/66b in any case.

10 gigabit ethernet is not 1 GB/s. It's 10 gigabits of data per second, or 1.25 gigabytes per second. The encoding is not an issue with these data rate numbers because Ethernet quotes their data rate as a data rate.
