AMD's next-gen GPU architecture has appeared in new Linux kernel patches as GFX13 updates roll out
The suite of GFX13 patches aren't particularly exciting in themselves, but they do suggest there might actually be some new GPUs next year.
AMD's upcoming next-gen GPU architecture, RDNA 5, has been spotted in the latest GFX13 updates in the AMDGPU Linux kernel driver. Michael Larabel at Phoronix first reported on these GFX13 patches, which were posted by AMDGPU maintainer, Alex Deucher. The RDNA 4 GPUs, including the Radeon RX 9070 XT and similar models, were previously referred to under the GFX12 codename.
The appearance of GFX13 hints at AMD's upcoming RDNA 5 architecture featuring new GPUs. These driver patches suggest that support for the new GPUs may be included in the upcoming Linux 7.5 kernel release, which is expected to come out in early 2027. This Linux release will also mark the end of optimizations for Intel's MMX multimedia extensions, which were introduced in the Pentium era.
While the current expectation for AMD's GPU release schedule is a mid-range RDNA 5 card in 2027, codenamed AT2, the actual code updates in this series do not reveal new features of the RDNA 5 feature set. However, it is worth keeping an eye on these updates, as future patches could potentially reveal more about the RDNA 5 architecture.
