Phenom II is a family of AMD multi-core 45 nm central processing units, succeeding the original Phenom. In this video you'll see AMD Phenom II Overclocked to 6.5GHz and new world record for 3DMark.

The Phenom II range of CPUs is the first series of AMD CPUs to eliminate the "cold bug" (a physical phenomenon which causes the processor to cease functioning below a certain temperature. This bug prevents the use of "extreme" cooling methods such as dry ice or liquid nitrogen). With the elimination of this cold bug, these CPUs are expected to overclock to much higher levels than any other AMD CPU range.
