Linux 6.5+ Is Great For The Lenovo ThinkPad P14s Gen 4 / AMD Ryzen 7 PRO 7840U
For some video encoding workloads Linux 6.6 was edging slightly higher.
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.
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.
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.
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.
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.
