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.

New: Athlon II X3 and Athlon II X4

Today’s AMD processor introduction, the Athlon II X4, represents the first step to introducing Deneb-based triple- and quad-core processors that run without L3 caches. AMD started with the Athlon II X4 620 at 2.6 GHz, but two models at higher clock speeds will also be available shortly. The Athlon II X3 has already appeared on several roadmaps and will be introduced at the same time.

Other than that, AMD is about to switch from its C2 stepping to C3, which should reduce the TDP on a number of processors. For instance, the Phenom II X4 965 flagship is expected to go from 140W to 125W and the Phenom II X4 945 will change from 125W to 95W.
