Athlon II X2 250u is one of the first K10-based ultra low power microprocessors, released in the forth quarter of 2009. Feature-wise the 250u is nearly undistinguishable from other Athlon II X2 CPUs - it has per-core 128 KB level 1 and 1 MB level 2 caches, 64-bit instructions, Enhanced Virus protection (disable bit) feature, support for SIMD instructions up to SSE4A, and works with DDR2 and DDR3 memory. The model 250u has much lower power dissipation than other Athlon II CPUs, even energy efficient ones. Performance-wise this CPU is slower than standard and middle-power Athlon II due to lower operating frequency. Currently (January 2010) this processor is being offered only in OEM systems, such as HP Pavilion All-in-One MS225 desktop PC, or Lenovo C305.
