The past few days I've been looking at
the CPU scaling driver, Linux kernel versions, and other areas for trying to figure out why the new AMD Zen+ CPUs on Linux were coming up a bit short of Windows.
My testing of this new AMD X470 motherboard from ASUS up until now was the default BIOS 0505 that is also what AMD was distributing to other reviewers as the BIOS for at-launch.
But now there is the Version 0509 build. The sole public change listed is updating to AGESA 1.0.0.2a.
I upgraded to BIOS 0509 from 0505 and ran a fresh round of benchmarks... This is while keeping all other system BIOS settings and other hardware the same during the benchmarking process.
