AMD's upcoming Phenom II X6 "Thuban" processors will reportedly implement Dynamic Speed Boost, a technology similar to Intel's Turbo Boost technology. This feature improves single-thread performance by disabling idle cores and overclocking active cores.
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 is a clear trend towards increase of the number of cores inside central processing units (CPUs), just five years ago a dual-core chip was a dream, whereas now we are approaching six-core microprocessors. The software is, unfortunately, seriously behind the hardware and many applications still cannot take advantage of additional cores, but fully depend on clock-speeds. In order to provide maximum possible performance in such programs, developers of CPUs implement special dynamic performance boosting technologies that disable certain cores and overclock the rest.
