AMD RadeonSI Gallium3D Performance For 4K Linux Gaming

AMD RadeonSI Gallium3D Performance For 4K Linux Gaming: While we routinely carry out Ultra HD (4K) Linux graphics/gaming benchmarks at Phoronix, it's generally been conducted with the proprietary NVIDIA and AMD graphics drivers since the open-source drivers traditionally have had a challenge on performance even at 1080p. However, thanks to the maturing open-source Radeon driver stack, it's possible with higher-end AMD graphics processors with the latest open-source Linux driver code to begin running at the 4K UHD resolution of 3840 x 2160.
