AOM AV1 benchmark with settings of Encoder Mode: Speed 11 Realtime, Input: Bosphorus 4K. Linux 6.6 Git was the fastest.

AOM AV1 benchmark with settings of Encoder Mode: Speed 9 Realtime, Input: Bosphorus 4K. Linux 6.6 Git was the fastest.

x265 benchmark with settings of Video Input: Bosphorus 4K. Linux 6.6 Git was the fastest.

For some video encoding workloads Linux 6.6 was edging slightly higher.

Blender benchmark with settings of Blend File: BMW27, Compute: CPU-Only. Linux 6.4.16 was the fastest.

LuxCoreRender benchmark with settings of Scene: Rainbow Colors and Prism, Acceleration: CPU. Linux 6.4.16 was the fastest.

RawTherapee benchmark with settings of Total Benchmark Time. Linux 6.4.16 was the fastest.

For demanding, long-running, and multi-threaded workloads like Blender and LuxCore there doesn't end up being much of a difference on Linux 6.5+ from the AMD P-State change.

WireGuard + Linux Networking Stack Stress Test benchmark with settings of . Linux 6.6 Git was the fastest.

Linux 6.6 did bring a very nice speed-up on this Lenovo ThinkPad P14s Gen 4 AMD laptop for the WireGuard open-source secure VPN tunnel solution.

CPU Power Consumption Monitor benchmark with settings of Phoronix Test Suite System Monitoring.

Overall across the course of dozens of benchmarks run, Linux 6.5 and 6.6 Git were trending slightly lower when it came to the CPU power consumption.

CPU Peak Freq (Highest CPU Core Frequency) Monitor benchmark with settings of Phoronix Test Suite System Monitoring.

With Linux 6.5+ on AMD P-State EPP, the Ryzen 7 PRO 7850U was also able to hit slightly lower frequencies and overall be more efficient than with the ACPI CPUFreq driver.

CPU Temperature Monitor benchmark with settings of Phoronix Test Suite System Monitoring.

The CPU temperatures though for those curious didn't change much on Linux 6.5+ for this Lenovo ThinkPad laptop.

Fortunately, Ubuntu 23.10 is using Linux 6.5 by default as is the upcoming Fedora Workstation 39 and other recent/upcoming Linux distribution releases. Linux 6.5+ overall has been performing quite nicely for AMD Ryzen systems with AMD P-State EPP for desktops, servers, and now some hard numbers on the mobile side.
