AMD's much talked about six-core processors, the Phenom II X6 series, consists of three models for what we know in good detail
: model numbers 1075T, 1055T, and 1035T at the bottom. But what remained a mystery were their clock speeds. A leak by one of the motherboard manufacturers who recently released supportive BIOS updates reveals the clock speed for the entry-level Phenom II X6 1035T to be 2.60 GHz, that of the 1055T to be 2.80 GHz, and of the high-end 1075T to be 3.00 GHz. As revealed earlier, the 1035T has a TDP of 95W, while the 1055T has both 125W and 95W variants in the making, and the 1075T has a TDP of 125W.
With so many motherboard vendors specifically designing their upcoming products to be ready for "140W TDP", it isn't hard to guess that there could be a higher-end part in the making, which is probably clocked even higher, and comes with the Black Edition branding. All Phenom II X6 processors are based on the "Thuban" core, a port of the Istanbul six-core architecture to the AM3 package. There are six cores with dedicated 512 KB of L2 caches and a shared 6 MB L3 cache (total cache being 9 MB). The new chip will be announced in the weeks to come.
