CachyOS Sets the Pace in Workstation Performance Benchmarks

The rise of the Steam Deck has sparked renewed interest in Linux, leading to a surge in Linux distributions optimized for performance. Among these, CachyOS stands out for its kernel-level enhancements aimed at delivering superior speed and efficiency. Recent benchmarking by Phoronix highlights just how effective these optimizations can be, positioning CachyOS as a top contender in the workstation operating system landscape.

Benchmarking CachyOS Against Leading Operating Systems

Phoronix conducted a comprehensive comparison between CachyOS, AlmaLinux 10.2, Ubuntu 26.04, Fedora Workstation 44, and Windows 11. The tests were performed on a high-end HP Z4 G6i workstation equipped with a 48-core Intel Xeon 678X Granite Rapids WS CPU, 128 GB of DDR5-6400 memory, and an NVIDIA RTX Pro 6000 Blackwell GPU—hardware valued at over $46,000.

Across a suite of CPU and GPU benchmarks, CachyOS consistently ranked at or near the top. In performance mode, CachyOS achieved the highest geometric mean in the workstation benchmark suite. Notably, Windows 11 Pro trailed behind, registering 14.9% slower performance compared to CachyOS in performance mode. While Windows did secure some wins in specific tests, the overall results favored Linux distributions, particularly CachyOS.

Detailed Performance Insights

The benchmarking suite included a variety of real-world workloads:

  • 3D Rendering and Modeling: Blender and IndigoBench 4.4 were tested in both CPU and GPU modes. CachyOS and AlmaLinux outperformed Windows 11 in both CUDA and CPU compute tasks. The most significant gap appeared in CPU-only rendering, where Windows lagged up to 12% behind CachyOS. Ubuntu and Fedora also trailed CachyOS, but only by 3-4%.
  • V-Ray 6.0 Rendering: Results varied depending on the rendering engine. Windows 11 led by 6% in RTX testing and by 2% in CUDA rendering. However, in CPU rendering, Linux regained the advantage, with CachyOS outperforming Windows by 18% and maintaining a slight edge over other Linux distributions.
  • Other Benchmarks: In Neatbench video benchmarking, GravityMark 1.87, Unigine Superposition 1.0, and OctaneBench, CachyOS frequently led the pack. In OctaneBench, only CachyOS in performance mode and AlmaLinux managed to surpass Windows. FluidX3D fluid dynamics simulations showed nearly identical results across all systems, with Windows narrowly ahead by fractions of a percent.
  • Rendering and Compression: OSPRay Studio and LuxCoreRender produced mixed results, with Windows occasionally matching or slightly outperforming Linux, but also falling significantly behind in other tests. In 7-Zip compression benchmarks, Linux distributions—including CachyOS—consistently outperformed Windows, though differences among the Linux options were minimal.

Conclusion: Linux Performance Gains Are Real

The latest benchmarks underscore the progress Linux distributions like CachyOS have made in optimizing for workstation performance. While Windows 11 still holds its ground in certain application-specific scenarios, CachyOS and its Linux peers are proving to be compelling choices for users seeking maximum performance, especially in demanding professional workloads. As Linux adoption continues to grow, these results highlight the value of exploring alternative operating systems tailored for speed and efficiency.
