Benchmarking a $46k Xeon HP Workstation: CachyOS in the Linux Performance Spotlight
Phoronix compares Windows 11 Pro and several Linux distributions—Ubuntu 26.04 LTS, AlmaLinux 10.2, CachyOS, and Fedora Workstation 44—on an HP Z4 G6i with a 48-core/96-thread Xeon 678X, 4x32GB DDR5, and RTX Pro 6000. AlmaLinux uses the Intel P-State performance governor by default, with a separate CachyOS “Performance” run to mirror that setup. The goal is to assess which OS delivers the best overall throughput for demanding workloads on a high-end workstation, with tests spanning multiple creator and compute workloads across a roughly $46k system configuration.
