Thuban hexacores appear on AMD roadmap

Two slides have surfaced showing AMD’s CPU roadmap. The slides show the arrival of four Thuban hexacores with different clock speeds and TDPs. AMD would also release a hexacore with two cores disabled.

The slides surfaced at the German Ati-forum.de and mention the AMD Phenom II X6 1000T Series. The hexacore CPUs are made from the Thuban core, the desktop version of the Istanbul core, which is used for server CPUs. The six cores each have 128KB L1 cache and 512KB L2 cache, and share 6MB L3 cache. The processors would be named Phenom II X6 1075T, 1055T and 1035T. The 1075T will get a TDP of 125W, while the 1055T will be available with a TDP of 125W or 95W. The lowest clocked cpu, the 1035T, gets a tdp of 95W.

In addition to the various hexacores, AMD also plans to release a quadcore based on the Thuban core. That processor would be called the Phenom II X4 960T and the name suggests that the speed will be slightly lower than with the Phenom II X4 965, which is clocked at 3.4GHz. However, the 960T would get a tdp of 95W, which is 30W less than the tdp of the Phenom II X4 965. Another advantage of the 960T may be that the two disabled cores can still be activated.

Furthermore, it is rumored that Thuban will get a turbo mode, which the 960T would also have. According to the roadmap, the CPUs will be released ‘halfway through the second quarter’, so that the chips will probably be in stores in May.
