From the CPU-Z screenshot you can see that that design is based around a 64nm process codenamed Kuma. Kuma is actually a cut down version of the AMD Phenom processors that are currently out. First off it’s limited to a dual-core offering, which is kind of evident by the X2 part in the name.

Sharing the lower clocked Phenom’s specs the 7750 uses a 1.8GHz HT link, which also limits the integrated Northbridge’s frequency to 1.8GHz. Thanks to the K10 architecture the new Athlon gets official HT3.0 specs allowing it to communicate with the external Northbridge at higher speeds and K8 based Athlon’s cache memory has also changed thanks to the K10 architecture improvements. First off the L2 cache has been dropped to 512K per core (1MB total CPU L2 cache) however a 2MB shared L3 cache has been used – it is the same size that all Phenom CPU’s share giving it extra memory storage on the CPU.
