Richland,code name for AMD's highest-end APUs,finds its way into our lab in the form of A10-6700 and A10-6800K. Based on the Piledriver architecture and VLIW4 graphics,these chips are slight improvements to Trinity. Can they outshine Core i3,though?
showed us what the company's Jaguar and GCN architectures could accomplish between 4 and 25 W TDPs. But,on the desktop,AMD isn't quite ready to make the leap to a next-gen design. It just introduced its desktop-oriented Richland APUs,which aren't really new at all. Rather,you can think of them as power-optimized Trinity parts,sporting the same Piledriver-based x86 cores and VLIW4 graphics configuration. Moreover,Richland-based APUs have been available to mobile device makers for months. The only real revelation is that we're getting this update in the desktop and low-voltage mobile spaces now.

In the table above,we see the new mobile-oriented options spanning 17 to 25 W TDPs. Richland isn’t much different from Trinity,but it's more efficient thanks to specific Turbo Core optimizations that include a greater number of P-states to facilitate more granular power and performance levels.

And then we have the desktop-specific Richland parts. The very fastest model enjoys a 300 MHz base clock rate bump compared to the A10-5800K,along with official support for 2133 MT/s DDR3 memory (the other SKUs top out at 1866 MT/s memory). Also,its GPU is 44 MHz faster than the prior-gen version. And yet it fits within the same 100 W TDP.
On the other hand,the A10-6700 looks a lot like the -5800K,aside from a 100 MHz-lower base clock,a 100 MHz-higher Turbo Core ceiling,and a slightly quicker GPU. That one drops to a 65 W thermal limit.
