Linux 6.19 Brings 30% Performance Boost to Older AMD Graphics Cards, Thanks to Valve Developer
The upcoming Linux 6.19 kernel is set to deliver significant performance improvements for users of older AMD graphics cards, with testing showing gains of approximately 30% in some cases.
This development comes courtesy of engineering work by Valve, demonstrating the gaming company’s continued commitment to improving the Linux gaming experience.

A Major Driver Transition
According to testing conducted by Phoronix, a leading source for Linux hardware benchmarking, the kernel update introduces an important change for users of legacy AMD hardware. Specifically, graphics cards using the older GCN 1.0 and GCN 1.1 architectures—such as the AMD R9 390X—will now use the newer AMDGPU kernel driver by default, replacing the previous Radeon driver that had been the standard choice.
This transition represents months of development work by Valve engineers, who have been systematically bringing modern feature support to these older GPUs and refining the AMDGPU driver to a state where it could confidently become the default option.

Impressive Performance Gains
Independent testing has validated the benefits of this change. Benchmarks conducted on an AMD Radeon HD 7900 3GB—a graphics card that’s now 13 years old—showed the new driver outperforming its predecessor across all test scenarios. The most dramatic improvement came in the GravityMark 1.87 OpenGL test, though specifics of the performance delta varied by workload.
Beyond raw performance improvements, the switch to AMDGPU brings enhanced compatibility with modern graphics technologies. Support for features like the Mesa RADV Vulkan driver means these aging cards can now run certain games through Proton, Valve’s compatibility layer for Windows games on Linux. This extended functionality could breathe new life into hardware that might otherwise be considered obsolete.

Why AMD on Linux?
The improvements underscore why Linux users have historically favored AMD graphics hardware. AMD’s approach to open-source driver development has resulted in more mature and well-integrated software support compared to some alternatives. The company’s commitment to mainline kernel drivers means updates like this can be delivered directly through standard kernel releases, benefiting all users without requiring separate driver installations.
The Linux 6.19 kernel update is expected to be released in early 2025, following the typical kernel development cycle. For users still running these older AMD cards, the update promises to deliver measurable improvements without requiring any hardware upgrades or manual configuration changes.
This development also highlights Valve’s broader strategy of investing in Linux gaming infrastructure. Since launching the Steam Deck handheld gaming PC in 2022, which runs on a custom Linux distribution, Valve has increasingly devoted resources to improving the entire Linux gaming ecosystem—benefiting not just Steam Deck users but the wider Linux gaming community.
