Lastly, for now, a look at the Llama.cpp Vulkan performance on these older generation AMD Radeon graphics cards.

With the active AMDGPU regression thwarting the plans for a larger AMD Linux GPU EOY2025 comparison, that's all the data points for now if you were curious about the performance of older AMD Radeon graphics cards on the Linux 6.19 kernel and Mesa 26.0-devel. More benchmarks in the new year and hopefully with the RDNA3/RDNA4 hangs resolved.
