Similar to what I've shown in prior articles with Ryzen desktops, the Ryzen laptop was showing immediate gains too from Linux 6.5. For some workloads Linux 6.6 is another step-up.

The enhanced performance didn't come at the cost of increased power use but in fact Linux 6.6 is delivering the best performance-per-Watt of the tested kernels.

The leading web browser benchmark, JetStream 2, also showed nice improvements on Linux 6.5+ for this AMD Zen 4 laptop.

For common web browser workloads, Linux 6.5 and Linux 6.6 exhibit nice gains on AMD Ryzen thanks to the shift to AMD P-State EPP by default.
