Engineering:List of AMD Athlon X2 processors

Short description: none

The AMD Athlon X2 processor family consists of processors based on both the Athlon 64 X2 and the Phenom processor families. The original Athlon X2 processors were low-power Athlon 64 X2 Brisbane processors, while newer processors released in Q2 2008 are based on the K10 Kuma processor.
