AMD Radeon RX 480 On Linux
Under the Source Engine powered Insurgency first person shooter, the Radeon RX 480 was coming in at 134 FPS to the R9 Fury at 148 FPS -- and again both cards between the speeds of a GTX 960 and GTX 970 under Linux.
F1 2015 tends to not perform as well with AMD on Linux at this point in time but for what it's worth the RX 480 performance was just shy of the R9 Fury when using the AMDGPU-PRO driver stack.
