The differences between Richland and Trinity are not earth shattering but there are certainly some refinements implemented by AMD in the A10-5750.  One very noticeable one is support for DDR3-1866 as well as better power management for both the CPU and GPU; with new temperature balancing algorithms and measurement the ability to balance the load properly has increased from Trinity.  Many AMD users will be more interested in the GPU portion of the die than the CPU, as that is where AMD actually has as lead on Intel and this particular chip contains the HD8650G, with clocks of 720MHz boost and 533MHz base and increase from the previous generation of 35 and 37MHz respectively.  You can read more about the other three models that will be released over at The Tech Report.

Don't forget Josh either!

"AMD has formally introduced the first members of its Richland APU family. We have the goods on the chips and Richland's new power management tech, which combines temperature-based inputs with bottleneck-aware clock boosting."
