Last week I published a 16-way NVIDIA GeForce performance
comparison on Linux looking at the OpenGL performance evolution from the
GeForce 9800GTX to the GeForce GTX 980 Ti / TITAN X, in getting ready to
compare the long-term NVIDIA Linux performance to Pascal. This week I've
done similar tests on the AMD Radeon side and compared these OpenGL
performance and power consumption / performance-per-Watt numbers to NVIDIA."
