Besides the fact that they are carved out of the same piece of silicon by disabling components, all AMD FX series processors, from the quad-core FX-4000 series, to the eight-core FX-8000 series have one thing in common: they're all "unlocked", meaning they have an upwards-unlocked base-clock multiplier, which makes overclocking them a whole lot easier. Take that away and what do you get? A new Phenom II processor line. That's right, it is learned that AMD has a new line of Phenom II processors, eight-core for now, that are being carved out of the 32 nm Zambezi silicon.
Intuitively branded within the new Phenom II X8 and existing Phenom II X6 markers, these chips feature relatively lower clock speeds, meaning they will be priced low, competitive with Intel's sub-$200 Core i3 and Core i5 processors. AMD will also tinker with Zambezi's caches. The new chips came to light when some motherboard manufacturers leaked them on CPU support lists of certain motherboards, on their websites. For now we're getting to hear about two eight-core models, the 2.40 GHz Phenom II X8 2420, and 3.00 GHz Phenom II X8 3020; and two six-core models, the 2.50 GHz Phenom II X6 2520, and 2.80 GHz Phenom II X6 2820. Relevant details are tabled below. It beats us why AMD didn't take the opportunity (new silicon) to label these "Phenom III".
