In an attempt to provide maximum possible performance for enthusiasts, Advanced Micro Devices plans to implement a dynamic performance boost technology into its six-core processors known as Phenom II X6 “Thuban”. There are not a lot of details available at this point, but what we do know is that when single-thread performance is needed most, Thuban processors will automatically disable idle cores and overclock the remaining engines to the maximum possible level that is determined by general thermal design power. The technology will be completely hardware-based, hence, will work in any operating system that supports six-core chips. The technology is presently called “C-state performance boost”, however, it is more than likely that AMD will introduce a better sounding marketing name when it launches six-core chips in the second quarter of the year.
