AMD Radeon graphics cards offer better performance on Windows 11 vs Linux 6.2

This year we’ve seen multiple updates to the Linux operating system from AMD, Intel, and NVIDIA when it comes to covering open source in-core graphics cards or improvements in processing power, as well as video codecs, new technology leaks, and more. That being said, the latest tests conducted by Linux Hardware editor and website reviewer phoronics — as well as entrepreneur, Linux software engineer, and analyst Michael Larabel shed light on AMD Radeon Gaming performance in Windows 11 and Ubuntu Linux environments.

Windows 11 OS offers the best graphics performance for AMD Radeon GPUs vs Linux 6.2

Larabel uses several games available on PC and Linux operating systems. The games were selected from titles that performed extremely well on Steam Play on Linux compared to Windows 11. In the coming days, Larabel plans to put Intel and NVIDIA to similar tests to find out which performs better, especially heading into a new year . Today’s focus is on AMD.

The game titles handpicked by Larabel were:

The Phoronix editor also selected three benchmarks for the tests. The first benchmark handles Vulkan and OpenGL better, while the second and third from UNIGINE are better equipped for OpenGL.

Yesterday we announced that the Radeon RX 7900 XTX graphics cards were going through isolated but growing problems with overheating and loss of performance due to temperature spikes. It will be interesting to see if this affects performance. Larabel uses the AMD Radeon RX 6800 XT and Radeon RX 7900 XTX GPUs for this testing.

The Windows operating system used for testing is Windows 11 Pro Edition, which he mentions is updated with the current drivers available. In contrast, the AMD Radeon RX 6800 XT driver used is the Adrenalin 22.11.2 Recommended WHQL driver, and the AMD Radeon RX 7900 XTDX uses Adrenalin 22.12.2. The difference between the two drivers is that the 22.11.2 Recommended driver offers the latest updates for the Navi 2 GPU, while the 22.12.2 driver offers the latest RDNA 3 drivers.

With Linux, in Ubuntu 22.10, Larabel uses Linux 6.2-rc1 along with Mesa 23.0-devel, offering the best support for RDNA 2 and 3 architectures. The CPU used for testing is an Intel i9-13900K CPU with 32GB DDR5-6000 memory on an ASUS PRIME Z790-P WIFI mobo and a Solidigm P44 PRO 2 TB NVMe SSD.

Hitman 3 showed higher gains with Windows 11 Pro and the AMD Radeon RX 7900 XTX, while the AMD Radeon RX 6800 XT led near the same Steam Play performance on Linux and the standard Windows operating system (Windows was seven frames per second faster ). The same goes for both frame time and resolution, while the emphasis is on playing in a 4K environment.

Left 4 Dead 2 was the opposite, with OpenGL rendering showing better FPS on both AMD graphics cards than on Windows 11 Pro. However, Portal 2 returned to Windows with both graphics cards, but Linux was close competition on the latest GPU from AMD. Quake II RTX, especially with NVIDIA-centric ray tracing, was nearly identical on Windows and Linux, with ray tracing enabled showing the most similarities to ray tracing disabled. Linux slightly beat both in-game graphics card tests for the RADV ray tracing driver, which shows the amount of work that has gone into the driver’s compatibility and performance over the past year. But once again, in the 4K resolution tests, Windows 11 Pro outperformed Ubuntu. Strange Brigade also favored Windows 11 Pro over Ubuntu Linux and X-Plane 12.

The GravityMark 1.72 benchmark allowed Ubuntu Linux’s graphics to eclipse Windows 11 Pro most of the time, thanks to the RadeonSI Gallium3D driver and Vulkan driver support, including 4K resolution settings. Larabel notes that the UNIGINE Heaven benchmark is slowly aging, but remains relatively faithful to native OpenGL benchmarking. Windows 11 did show the most significant improvement in the Heaven benchmark tests, but it flipped the Superposition benchmarks, gaining only a slight lead over Windows.

Next up for the Phoronix editor will be Intel Arc Graphics and NVIDIA’s newer RTX 40 series GPUs in the coming days. You can check all the benchmark results on his Phoronix websiteand you can check out his other projects on his professional portfolio site,
