AMD launches AM3 Phenom II CPUs.

Processor name	Clock speed	L3 cache
Phenom II X4 925	2.8GHz	6MB
Phenom II X4 910	2.6GHz	6MB
Phenom II X4 810	2.6GHz	4MB
Phenom II X4 805	2.5GHz	4MB
Phenom II X3 710	2.6GHz	6MB
Phenom II X3 720 Black Edition	2.8GHz	6MB

AMD AM3 Phenom II CPUs support DDR2 and DDR3 memory and aim to take on Intel’s Core 2 chips.

As you probably already know from the AM3 motherboards that have already been announced, AM3 is AMD’s first foray into DDR3 memory support. As Phenom CPUs have integrated memory controllers, it’s more accurate to say that it’s the new range of Phenom II CPUs (see below) that are DDR3-compatible. However, the new DDR3-compatible Phenom II range is also compatible with DDR2 memory.

As the new CPUs and the new AM3 socket are pin-compatible with the current AM2+ socket, you can put a new AM3-compatible CPU into an existing AM2+ motherboard. This means that you can upgrade your CPU now without needing to change your motherboard or buy pricey new DDR3 memory.

AMD has today announced six new 45nm Phenom II CPUs that use the AM3 socket, and they all have a quoted maximum TDP of 95W, as well as the usual 512KB of L2 cache per core. Each core also gets 64KB of L1 data cache and 64KB of L1 instruction cache, although the amount of shared Level 3 cache varies between the range, with some chips getting 4MB and others getting 6MB.
