AMD Renoir Seeing Nice Uplift Moving From Ubuntu 20.04 To 22.04 LTS

One of the areas that tends to drive the biggest gains for desktop-class hardware with new Linux releases is the ever-improving open-source graphics drivers... In the case of the AMD Ryzen 7 4800U with Vega graphics, Ubuntu 22.04 LTS is bringing some nice gains over Ubuntu 20.04.4 LTS -- and that being the graphics stack as well of Ubuntu 21.10. In most of the graphics benchmarks carried out, the Ryzen 7 4800U APU was enjoying very nice performance gains. Surprisingly though the Intel Gen9 Comet Lake graphics were regressing by a measurable amount in many of these tests. Seeing the Intel Gen9 slowdown on Ubuntu 22.04 LTS was unexpected and something I'll be looking more at separately to see if it's widespread or more of an isolated issue.

The graphics improvements on Ubuntu 22.04 LTS with AMD Renoir carried through to workstation visualization OpenGL benchmarks with ParaView too -- more real-world for OnLogic industrial PCs than games.
