Early Windows 11 25H2 benchmarks confirm the update provides no performance improvements over 24H2

Windows Phoronix Microsoft
Windows 11.

Windows 11 25H2 is not out yet, but that hasn't stopped media outlets from benchmarking the upcoming Windows 11 version. Phoronix tested Windows 11 25H2 against Canonical's upcoming Ubuntu 25.10, Ubuntu 24.0.3 LTS, and Windows 11 24H2 in a head-to-head benchmarking battle to see if 25H2 delivers any new performance improvements. Sadly, though, Phoronix's testing revealed that 25H2 was unable to outperform 24H2, even technically losing to its predecessor in many tests.

The four operating systems were tested using a Ryzen 9 9950X paired with 32GB of DDR5 memory. Phoronix benchmarked a variety of applications (41 benchmarks in total), including LuxCoreRender, Embree, Intel Open Image Denoise, OSPRay, and IndigoBench.
