AMD A10-5800K "Trinity" APU On Linux
The Unigine Engine is very tough on graphics cards and drivers, but while the Radeon HD 7660D frame-rate for Unigine Heaven at 1680 x 1050 was only 6.57 FPS, that was ahead of the mid-range Radeon HD 6570 graphics card and the lower-end GPUs.
For the older Unigine Tropics technology demo, the Radeon HD 7660D graphics performance came up short of the Radeon HD 6570 by a measurable margin.
