Quote:AMD fixes HandBrake scaling, Threadripper now up to 215% faster

HandBrake finally uses more Threadripper cores.



AMD says it helped fix two threading bottlenecks in HandBrake, the open-source video transcoding tool. The changes are now part of HandBrake 1.11.0 and newer versions.

The fix targets high-core-count CPUs. AMD found that HandBrake was not scaling properly beyond 64 logical processors. On some systems, this meant that adding more CPU resources did not always make the encode faster. In some lower-resolution tests, performance could even drop by up to 60%.

The second issue was tied to how HandBrake split work across CPU threads. Some jobs were too small, so the CPU spent too much time managing tasks instead of doing the actual transcode. This was seen mainly in 720p workloads, where scheduling overhead can take a larger part of the total processing time.
