AMD Turion II Neo K645

The AMD Turion II Neo K645 is a laptop processor for small and thin subnotebooks. It is part of the Nile platform in conjunction with the AMD M880G chipset (Radeon HD 4225 on board graphics). Compared to the slower Athlon II and V Series CPUs, the Turion II offers a 128 Bit FPU and 1.6 GHz HyperTransport Link (compared to 64 Bit and 1 GHz). The integrated memory controller supports DDR3-1066 memory.

The performance of the CPU is compareable with 1.3-1.4 GHz Core 2 Duo processors (e.g., SU7300, SU9400). The power consumption of a Nile platform laptop (M301z) was higher than compareable SU based Intel systems. Still, the PCMark Vantage results were better.
