AMD has worked with HandBrake to fix performance bottlenecks that were limiting high core count Threadripper CPUs, leading to major gains in video transcoding. With newer HandBrake versions, AMD says Threadripper PRO chips can see up to 181 percent higher performance, while Ryzen Threadripper HEDT CPUs can see gains of up to 215 percent in some workloads.
The problem was not that Threadripper lacked raw power. Instead, HandBrake was not scaling properly across very high thread counts. On CPUs with more than 64 logical processors, the app could leave available compute resources underused. Some workloads were also split into very small jobs, which increased scheduling overhead and hurt performance, especially in lower resolution tests.
The fixes arrived in HandBrake 1.11.0 and later versions, with testing shown using HandBrake CLI 1.11.1 compared with CLI 1.6.1. The result is a large boost for users who rely on Threadripper systems for video encoding and transcoding.
Why HandBrake was not using Threadripper properly
Video transcoding can benefit from more CPU cores, but only when the software divides work efficiently. That was the issue AMD found with HandBrake on Threadripper systems.
HandBrake had trouble scaling beyond 64 logical processors. On high core count CPUs, that meant some cores were not being used as effectively as they should have been. The app also split some workloads into jobs that were too small, creating extra overhead. In simple terms, the CPU spent too much time organizing work instead of doing the actual transcode.
| Issue | Impact |
|---|---|
| Limited scaling beyond 64 logical processors | High core count CPUs were underused |
| Small job splitting | More scheduling overhead |
| Lower resolution workloads | Bigger CPU overhead penalty |
| Result before fixes | Performance could drop instead of scaling |
| Fix | Better thread management and job scheduling |
| Updated version | HandBrake 1.11.0 and later |
For workstation users, this is exactly the type of software level issue that can hide the value of expensive hardware.
The biggest gains appear in 720p and 8K workloads
AMD’s test results show very large improvements across several workloads. The Ryzen Threadripper 7980X saw up to 215 percent higher performance in the Perfume H.264 720p test. It also gained 203 percent in an LG 8K HEVC 8 bit 4320p workload.
Threadripper PRO also saw major gains. The Threadripper PRO 9995WX 96 core chip improved by up to 181 percent in Perfume H.264 720p, while several HEVC 8K and 4K workloads improved by more than 140 percent.
The size of the gains varies depending on codec, resolution, and workload type. Still, the message is clear. HandBrake now makes much better use of Threadripper CPUs than it did before.
What changed in the newer HandBrake versions
The fix focuses on how HandBrake manages threads and schedules work across the CPU. Instead of running into scaling limits or wasting time on overly small chunks of work, the newer versions divide transcoding tasks more efficiently.
That is especially important for CPUs like Threadripper and Threadripper PRO, which are built for heavy parallel workloads. These chips often have far more cores and threads than mainstream desktop CPUs, so software needs to be designed to take advantage of them.
Without that support, a high end workstation can perform far below expectations. With better scheduling, those same systems can finally show the kind of performance users paid for.
Why this matters for creators and workstation users
HandBrake is widely used for video conversion, encoding, and compression. Many creators, editors, archivists, and workstation users rely on it because it is free, flexible, and supports a wide range of formats.
For people using Threadripper systems, this update can save a meaningful amount of time. Large video batches, high resolution files, and repeated encoding jobs can take hours. A major performance boost can reduce wait times and make a workstation more productive.
The update also shows why software optimization matters as much as hardware. A powerful CPU can only deliver its full value when the apps running on it are able to scale correctly.
Threadripper owners should update HandBrake
Anyone using AMD Threadripper or Threadripper PRO for transcoding should make sure they are running HandBrake 1.11.0 or newer. Older versions may leave a lot of performance unused, especially on high core count systems.
The improvement is not just a small bug fix. In some cases, the difference is large enough to change how useful a Threadripper workstation feels for video work.
AMD deserves credit for identifying the issue and helping improve support for its workstation CPUs. HandBrake users also benefit because the fix makes the app more capable on modern high core count hardware.
For Threadripper owners, this is one of the rare updates that can make existing hardware feel much faster without buying anything new.
