Ubuntu 19.10 To 21.10: AMD Zen 2 + Radeon Performance On Linux Over Two Years

The performance from Ubuntu 19.10 to 21.10 was moving in the right direction with only few regressions.
These performance improvements come thanks to the newer GCC compiler as well as Linux kernel enhancements over the past two years.
