Linux 5.11: Good News for AMD Users

The latest release of the Linux kernel features some impressive performance enhancements for AMD hardware.

Released over the valentine’s day weekend, Linux kernel 5.11 fixed a major performance regression that impacted the AMD Zen architecture. Thanks to the fix, Zen-based processors such as Ryzen and EPYC have been benchmarked as being faster out of the box than on previous kernels. Also debuting in the release is support for AMD “Van Gogh” and “Dimgrey Cavefish” GPUs.

Hmm, I’m interested to put that to a test. Does someone know an easy way to benchmark my CPU for future comparison?

There was some benchmark script posted by a former member (@torvic9). Not sure where to find it now. I would be interested as well.

"AMD users should immediately switch to the latest Linux 5.11 kernel" . This is nonsense.

The performance regression for AMD processors was first introduced in the early 5.11 versions. It is not in 5.10. And it is fixed now in the latest 5.11 kernel. No need for anybody to move to 5.11.
