With SVT-AV1 as Intel's great open-source AV1 video encodeer, the amd_pstate_epp powersave mode continued to deliver the best performance-per-Watt behind acpi-cpufreq powersave while still delivering good throughput performance.

Turning to browser benchmarks, amd_pstate_epp powersave power was continuing to look quite good.

Selenium benchmark with settings of Benchmark: Jetstream 2, Browser: Google Chrome. amd_pstate_epp powersave performance was the fastest.

With the demanding JetStream 2 benchmark, the amd_pstate_epp powersave power mode was behind acpi-cpufreq powersave but still delivering raw performance aligned with them ore performance-minded modes.

7-Zip Compression benchmark with settings of Test: Compression Rating. amd_pstate_epp powersave balance_performance was the fastest.
7-Zip Compression benchmark with settings of Test: Decompression Rating. amd-pstate performance was the fastest.
7-Zip Compression benchmark with settings of Test: Decompression Rating. amd-pstate performance was the fastest.
7-Zip Compression benchmark with settings of Test: Decompression Rating. amd-pstate performance was the fastest.

With 7-Zip the amd_pstate_epp powersave power numbers continued to look quite compelling from the performance-per-Watt vs. performance tradeoff.

Zstd Compression benchmark with settings of Compression Level: 19, Compression Speed. acpi-cpufreq performance was the fastest.
Zstd Compression benchmark with settings of Compression Level: 19, Decompression Speed. amd_pstate_epp powersave balance_performance was the fastest.
