The equivalent cppc driver is on Linux, along with a sysfs interface that lets you override cache (CCD) preference per-application, like you can via Registry on Windows.

AMD has very solid Linux drivers. I forgot which CPU it was recently, but AMD had to delay the release because the Windows drivers weren't ready, despite having Linux drivers already included in kernels.

Can't speak to that exact CPU - but Linux tends to have excellent support for AMD. It's why Linux users strongly recommend using an AMD graphics cards. I'd be surprised if windows offered a better experience
