Phenom II X6 to Get C-State Performance Boost Feature

[Hector Ruiz]

AMD's upcoming six-core desktop processor, the Phenom II X6, will introduce a new feature to the Phenom II series, currently known as "C-state performance boost". The feature gives the processor control over individual cores' power states, and the ability to gate power down completely a core. The remaining active core(s), will then be overclocked beyond the normal clock speeds, so that low-power operation with reduced parallel computing load goes on with much lesser energy consumption.

Features such as C-state performance boost and 'power-gating' is relatively new for AMD processors. The two were originally expected to be introduced with AMD's 32 nm "Llano" Fusion APUs. AMD's Phenom II X6 is expected to be released in May 2010, its architecture is derived from the six-core "Istanbul" Opteron processors, albeit in the socket AM3 package that supports dual-channel DDR3 memory. There are as many as four models in the works for an initial release. Known details of these can be found here
