The OpenGL Speed & Performance-Per-Watt From The Radeon RX 480 To Radeon HD 4850/4870

The raw Insurgency results are boring when looking at the frames per second considering the Source Engine game is CPU bound at 1080p....

But looking at Insurgency's frames per second show how much more efficient the RX 480 is compared to previous generations of GPUs.

Portal also shows the performance evolution with AMD GPUs nicely going from the HD 4850 to RX 480, even though Portal isn't demanding at all with modern GPUs.
