AMD C-60 APU with Radeon HD Graphics


as used in the Acer Aspire One AO522-BZ436


I don't quite understand the marketing of these processors, AMD seem to spend a lot of time in developing these products but there is very little promotion of them and they seem to turn up in notebooks and Netbooks that are in the "lower" end of the market space.

In addition, the AMD processors are used in equipment that manufacturers also delegate to use Insyde H2O BIOS. The consequence is that the features of the AMD Llano platform cannot be realised as the EFI BIOS effectively negates any over clocking and turbo boosting of either the CPU or graphics adapter.

Drivers for the GPU

The GPU that is coupled with this processor (APU) is different to the one that is paired with the C-50. It could be due to the newness of this GPU that is behind the fact that the drivers are difficult to come by. I didn't make a backup of them before I re-installed Windows and the Catalyst Display driver (downloaded from the AMD website at that time ****** ) does did not seem to want to lay with the HD 6290 GPU.

AMD VGA Chip UMA

When I downloaded the drivers for the HD 6290 and the AMD C-60 APU and chipset it was "hot off the blocks". Since that time I believe that there are drivers available from AMD.

Looking at the folder structure of the driver package it is interesting to note the use of the term UMA. This is getting to be somewhat an antiquated term but still describes the general arrangement for the useage of shared memory between the CPU and GPU. AMD seem to (or at least claim - this is somewhat born out by the performance) improved on the technology that has been used for at least the last decade.

When installed the Catalyst Control Center adds a GUI that can be used to "preset" the perfomance of the computer that the AMD chipset is used in.
