SVT-AV1 benchmark with settings of Encoder Mode: Preset 4, Input: Bosphorus 4K. 6.1.7-zen1-1-zen was the fastest.
SVT-AV1 benchmark with settings of Encoder Mode: Preset 8, Input: Bosphorus 4K. 6.1.7-arch1-1 was the fastest.
SVT-AV1 benchmark with settings of Encoder Mode: Preset 12, Input: Bosphorus 4K. 6.1.7-zen1-1-zen was the fastest.
SVT-AV1 benchmark with settings of Encoder Mode: Preset 13, Input: Bosphorus 4K. 6.1.7-zen1-1-zen was the fastest.
uvg266 benchmark with settings of Video Input: Bosphorus 4K, Video Preset: Very Fast. 6.1.7-arch1-1 was the fastest.
uvg266 benchmark with settings of Video Input: Bosphorus 4K, Video Preset: Super Fast. 6.1.7-arch1-1 was the fastest.
uvg266 benchmark with settings of Video Input: Bosphorus 4K, Video Preset: Ultra Fast. 6.1.7-arch1-1 was the fastest.

For video encoding workloads like the speedy SVT-AV1 encoder or uvg266 for H.266, there wasn't much of a difference besides the Linux 5.15 LTS kernel being the slowest due to optimizations merged in more recent versions that benefited the AMD Ryzen 9 7950X execution.

7-Zip Compression benchmark with settings of Test: Compression Rating. 6.1.7-arch1-1 was the fastest.

For 7-Zip compression both the Linux LTS and hardened kernels were the slowest.
