Having already tested the Radeon HD 6550D graphics on the AMD A8-3850 under Linux back in July, plus with the Catalyst Linux overclocking of the A8-3870K not working out right now, this article isn't too much more than just an updated look at the performance with the more recent Catalyst Linux driver. Ubuntu 12.04 LTS with the Linux 3.2 kernel was also used for testing.
The test system was using the Sapphire Pure Platinum A75 motherboard, 4 x 4GB of DDR3 system memory, a 240GB OCZ Vertex 3 SATA 3.0 SSD, and the various Radeon graphics configurations. The A8-3850 was re-tested along with running the Radeon HD 4550, Radeon HD 5450, and Radeon HD 5750 discrete graphics cards as some of the other low and mid-range graphics cards against the Radeon HD 6550D. The A8-3870K graphics were tested when the APU was running at 3.0GHz (the stock frequency) and 3.6GHz as a modest overclock.
All of the graphics were tested when using the Catalyst Linux driver, but a look when running the open-source driver stack with the latest Linux kernel DRM and Gallium3D driver is forthcoming.
