We will stop here, as we’ve listed all 45nm AMD processors. There still are lots of 65nm chips based on the quad-core Agena (Phenom 9000-series) and the triple-core Toliman (Phenom 8000), as well as the Athlon X2, which is based on the dual-core Kuma. All of them were designed for Socket AM2+ and DDR2 memory, but since the 45nm generation is compatible with both AM3/DDR3 and AM2+/DDR2, this is clearly the better choice.
