AMD Threadripper CPUs Get Huge HandBrake Performance Boost After Core-Scaling Fix
AMD has helped unlock major performance gains for its Ryzen Threadripper and Threadripper PRO processors in HandBrake, with improvements reaching up to 215% in some video transcoding workloads.
HandBrake is one of the most popular tools for video encoding and transcoding, and it is exactly the kind of application that should benefit from CPUs with large numbers of cores. In theory, processors such as AMD’s Threadripper chips should excel in these tasks, especially when handling demanding formats like H.264, HEVC, 10-bit video, 4K, and 8K content.
However, AMD found that HandBrake was not fully taking advantage of its high-core-count Threadripper processors. Instead of scaling cleanly as more cores were added, performance could actually fall in certain workloads, particularly at lower resolutions where CPU overhead became more noticeable.
The issue was traced to how HandBrake handled systems with more than 64 logical processors. Older versions of the software were not optimized to efficiently manage CPUs with extremely high thread counts. As a result, some available processing resources were left underused, preventing Threadripper processors from delivering their full potential.
A second problem came from the way certain encoding jobs were divided. Some workloads were split into tasks that were too small, creating unnecessary scheduling overhead. This was especially visible in 720p video tests, where the processor could end up spending too much time coordinating the workload rather than performing the actual transcode.
Together, these issues could cause a performance drop of up to 60% in some cases.
With HandBrake 1.11.0 and newer versions, AMD worked on improvements that better support high-core-count CPUs. The fixes include more efficient thread management and improved job scheduling, allowing HandBrake to distribute transcoding work more effectively across Threadripper processors.
The result is a significant uplift in video encoding performance.
According to AMD’s testing, the Threadripper PRO 9995WX, a 96-core workstation CPU, now delivers up to 181% higher performance in HandBrake. Meanwhile, the Ryzen Threadripper 7980X, a 64-core high-end desktop processor, sees gains of up to 215%.
AMD compared results using HandBrake CLI 1.11.1 against the older HandBrake CLI 1.6.1, showing how much the software-side improvements matter for modern high-core-count processors.
For the Threadripper PRO system, some of the biggest performance gains included:
Perfume H.264 720p: up to 181% faster
Perfume HEVC 10-bit 2160p: up to 151% faster
LG 8K HEVC 8-bit 4320p: up to 149% faster
LG 8K 60fps HEVC 10-bit 4320p: up to 145% faster
Perfume HEVC 10-bit 1080p: up to 91% faster
For the Ryzen Threadripper HEDT platform, the gains were even larger in certain tests:
Perfume H.264 720p: up to 215% faster
LG 8K HEVC 8-bit 4320p: up to 203% faster
LG 8K 60fps HEVC 10-bit 4320p: up to 105% faster
Perfume HEVC 10-bit 1080p: up to 73% faster
Perfume HEVC 10-bit 2160p: up to 63% faster
These results show how important software optimization is for today’s workstation-class CPUs. Hardware with dozens of cores can offer massive performance potential, but applications need to be designed to schedule work properly across all available threads.
For creators, editors, and professionals who rely on HandBrake for video transcoding, the update could mean dramatically shorter encode times, especially when working with high-resolution content such as 4K and 8K video.
This is also a strong win for AMD’s Threadripper platform. The fix helps these processors perform closer to what users would expect from high-end workstation and enthusiast CPUs, particularly in heavily threaded media workloads.
Anyone using a Threadripper or Threadripper PRO processor with HandBrake should make sure they are running version 1.11.0 or newer to take advantage of the improved performance.
