# List of AMD Athlon X2 processors

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.
