Windows 11 vs. Ubuntu Linux Performance For Intel Core Ultra X7 Panther Lake
First up were some cross-platform graphics benchmarks for evaluating the Xe3 Arc B390 graphics state under Windows and Linux. First up was the native 3DMark Wild Life Extreme on each platform that routes through Vulkan on Linux. Windows 11 was significantly faster than Ubuntu even with using the latest Linux 6.19 kernel and Mesa 26.1-devel Git state for the latest ANV driver support.
With 3DMark Solar Bay Extreme that leverages Vulkan ray-tracing, the Linux performance was around half that of the Microsoft Windows driver.
But when turning to OpenGL with the open-source Iris Gallium3D driver on Linux, with demanding OpenGL graphics like Unigine benchmarks, Linux came in quite close to Windows 11 for the Arc B390 OpenGL performance.
With Unigine Superposition there was still faster OpenGL performance on Windows but not by the margins observed with various Vulkan benchmarks.
With the OpenGL-rendered Xonotic cross-platform shooter game, at low quality settings Linux was faster but Windows 11 came out ahead at the higher resolutions.
