AMD Releases Two Llano Based Athlon II X4 CPUs
 

AMD has quietly released two Athlon II X4 CPUs, the 638 and 641. These are based on Llano (i.e. Stars+/K10.5 architecture) but lack an integrated GPU. The socket is still FM1, just like in normal Llano CPUs. Here's a quick rundown of the chips.

There is nothing extraordinaty in these chips. We are looking at relatively low-end SKUs in terms of price and performance. It's good to keep in mind that a discrete GPU is needed because these SKUs lack integrated graphics, so that will potentially raise the total system price.

The usage of the Athlon II brand with Llano isn't actually a new thing as the first such SKU, Athlon II X4 631, launched back in August. This is quite similar to what Intel is doing; AMD is saving the A4, A6, A8, and FX brands (their rough equivalent of Intel's Core i3/i5/i7) for midrange and high-end chips, and reusing their older Sempron and Athlon brand names (e.g. Intel's Celeron and Pentium) with lower-end SKUs.
