AMD Ryzen APUs Get Free Performance Boost With Linux 5.16, 28% Improvement

Latest Linux 5.16 kernel releases impressive performance improvements for AMD Ryzen APU owners, as proven Voronex.

Linux 5.16 Kernel for AMD Ryzen APUs Provides Up to 28% Performance Gain

Phoronix released a series of benchmarks on its recently released 5.16 Linux kernel, and it looks like users of AMD’s APU Ryzen have arrived. Performance benchmarks were conducted on the AMD Ryzen 7 Pro 5850U and Ryzen 5 5500, based on Zen 3 and Zen 2 architecture.

Various versions of the Linux kernel have been used to compare general improvements and include:

  • Linux 5.11 + Mesa 21.0.3
  • Linux 5.15.10 + Mesa 21.0.3
  • Linux 5.15.10 + Mesa 21.2.6
  • Linux 5.15.10 + Mesa 21.3.2
  • Linux 5.15.10 + Mesa 22.0-dev
  • Linux 5.16 + Mesa 22.0-dev

The biggest performance increase was recorded in Xonotic 0.8.2 with a 28% improvement over Linux 5.15.10 with Mesa22.0. The overall performance jump is around 5-10%, which is a solid upgrade for users with laptops running on AMD Ryzen APUs. Another laptop with the Ryzen 5 5500U also showed a nice increase in performance with up to a 14% increase in GLmark 2 and Xonotic and around a 7% increase on average overall.

This improvement with Linux 5.16 was great and came unexpectedly. Linux 5.16 has many new features Including AMDGPU kernel driver improvements, but this increase in Radeon Vega graphics came as a surprise, as no very advanced Vega graphics support and optimization has been announced at this point. It could also be a combination of 5.16 CPU optimizations.

This is definitely great news for AMD Ryzen APU laptop owners, and it seems definitely worth upgrading to the latest Linux 5.16 kernel, because you just need to make a profit. There are benchmarks that don’t see a huge jump in performance, but they also don’t have a performance dip compared to previous Linux kernels, so overall this is a beneficial situation for Ryzen owners. The stable release of Linux 5.16 kernel is expected on January 9th.
