Athlon II is a family of AMD multi-core 45 nm central processing units, which is aimed at the budget to mid-range market and is a complementary product lineup to the Phenom II.
The Athlon II series is based on the AMD K10 architecture and derived from the Phenom II series. However, unlike its Phenom siblings, it does not contain any L3 Cache. There are two principal Athlon II dies: the dual-core Regor die with 1 MB L2 Cache per core and the four-core Propus with 512 KB per core. Regor is a native dual-core design with lower TDP and additional L2 to offset the removal of L3 cache. The Athlon II x2 200e-220 chips have less L2 cache than the rest of the Regor line. The triple-core Rana is derived from the Propus quad-core design, with one core disabled. In some cases, the Phenom II Deneb die is used with disabled L3 cache and cores in the case. Includes: AMD Direct Connect Architecture AMD Wide Floating Point Accelerator AMD Digital Media XPress 2.0 Technology AMD PowerNow! Technology (Cool’n’Quiet Technology) HyperTransport Technology (not the same as Intel Hyper-Threading Technology)
Processors with an "e" following the model number (e.g., 245e) are low-power models, typically 45W for Athlons, 65W for Phenoms. Processors with a "u" following the model number (e.g., 250u) are ultra-low voltage models.
