Ryzen 9 7950X Performance With The New AMD P-State Default Of Linux 6.5
In some workloads were very minor changes in performance with Linux 6.5.
In other select workloads like real-time path-tracing with OSPRay there was a bump in performance when using Linux 6.5.
In some of the video encoding benchmarks there were slight improvements to the video encode speed and power efficiency when the Ryzen 9 7950X desktop was using Linux 6.5 with its new AMD P-State EPP default in powersave mode.
The x265 encoder with 1080p content saw one of the largest shifts in performance when upgrading to Linux 6.5.
On the whole the performance difference across the span of 62 benchmarks I ended up running there didn't end up being many dramatic shifts from Linux 6.5 with the out-of-the-box change from ACPI CPUFreq schedutil to AMD P-State EPP powersave. But as shown in this article with some of the affected results, areas like web browser (Firefox and Chrome) as well as video encoding are some of the areas where there can be better performance and power efficiency for AMD Ryzen desktop systems with Linux 6.5. Those using Linux 6.3+ currently can also already make use of the AMD P-State driver with amd_pstate=active. But besides this default change there are also many other features of Linux 6.5, which if all goes well will debut as stable on Sunday, 27 August.
