AMD's Propus is about to get another, faster iteration. In reality, Propus is a CPU derived from Deneb with no L3 cache, 2MB total L2 cache, or 512 for each core.

The CPU is a quad core, supports DDR3 1333 and comes in AM3 package. The currently fastest Propus is Athlon II X4 640 clocked at 3.0GHZ and Q3 should see it get topped by a 3.1GHz clocked part. The name of the new CPU is Athlon II X4 645, this CPU is clocked at 3.1GHZ and like its predecessor - it has a 95W TDP.

Let us remind you that this AM3 CPU should also work in many AM2+ based motherboards. The launch date of Athlon II X4 645 is Q3 2010 and we're talking about the quarter that started at the beginning of this month.
