AMD Radeon HD 7660D On Linux

Next up are some overclocking results under Linux for the Radeon HD 7660D graphics on the A10-5800K on the AMD Catalyst blob. The highest GPU core clock speed that could be safely reached in a stable manner was 1013MHz where as the HD 7660D is clocked at 800MHz by default. For reference, the GPU was also benchmarked mid-way between those two points at 894MHz. The GPU overclocking was handled by the UEFI/BIOS. (As a note for the table above, the system memory was actually running at DDR3-2133MHz but the DMI tables were being parsed by Ubuntu 12.10 at 1066MHz.)
