Linux 5.2/5.3 Kernel Performance On The AMD Ryzen 9 3900X

The 3900X doesnt hit the 4,6 Ghz yet on AGESA 1.0.0.3ab:

But according to for instance this collection of benchmarks: https://www.reddit.com/r/Amd/comment...0_application/
It is way ahead of the 9900K now. Only in gaming it is 8 % behind it, but there is still more to expect, once the Agesa versions get better.

I switched from a 2700X to a 3900X and theorethically that should be 45% boost. I can confirm that. When gaming my cpu needs to do dxvk conversion, wine translation, h.264 encoding and sometimes stream recording; but this thing has no issues to still let the games run at 120 fps. It doesnt even sweat, when the 2700X before was at its limit and 80 fps tops.

It would be great if Michael can show some gaming benchmarks on 3900x/3700x.

I wonder if these changes are going to influence the behavior on linux too: https://www.anandtech.com/show/14688...ppc2-upscaling

I really like the sub 1ms reaction to load of zen2 at launch. I would hate it if it changes to 17ms ...
A single core at 4Ghz can do 68E+6 instructions in 17ms (assuming conservative IPC of 1)

I would rather blacklist any acpi and p-states drivers, set the target to P0, CPB, XFR enabled and let the hardware manages idle C-States by it-self
