AMD: K10 (Stars)

CPU Charts 2012: 86 Processors From AMD And Intel, Tested
By , Achim Roos

AMD offers a great many multi-core CPUs built using its K10 architecture. The most modern models are sold under the Athlon II and Phenom II brands. The company code-named each unique configuration of cores and cache using stars, so the architecture is also commonly referred to as Stars as well.

Athlon II CPUs entered the market in 2009, manufactured using 45 nm process technology. They include two to four cores and drop into the Socket AM3 interface. Dual-core versions are branded as Athlon II X2, triple-core models are Athlon II X3, and the quad-core versions are sold as Athlon II X4. The Athlon IIs don't have any L3 cache.

In contrast, Phenom IIs do generally come with up to 6 MB of L3 cache, though AMD decided to get tricky and sell a few Phenom IIs with less or no L3 memory. The 45 nm Phenom II line-up is similarly named to indicate core count: from the dual-core Phenom II X2 to the hexa-core Phenom II X6, which was introduced in 2010.

The most modern Phenom IIs (the Thuban-based Phenom II X6 and Zosma-based Phenom II X4) also sport Turbo Core technology, which automatically overclocks up to half of the processor's cores when thermal conditions allow.
