One of the new features of AMD's upcoming Bulldozer server processors will be TurboCore, a codename for a new auto-overclocking technology that aims to provide big boosts in performance when using single-threaded applications. A similar technology is already available on Intel's Xeon processors in the form of Intel's TurboBoost technology.
"There will be a TurboCore feature for Bulldozer, but there will be some improvements from what you see in “Thuban”. There are some enhancements to give it more “turbo”. This will be the first introduction of the TurboCore technology in the server processors. We expect that this will translate into a big boost in performance when using single threaded applications, and there should be some interesting capabilities for heavier workloads as well," said John Fruehe, the director of product marketing for server/workstation products at AMD.
AMD's previous-generation and current generation Opteron microprocessors support CoolCore and/or CoolSpeed technologies that optimize power consumption and performance. The former can disable parts of the chip that are not used to trim power usage, whereas the latter can allow reducing p-states of microprocessors for certain periods of time so that to keep CPU operating even when thermal limits are reached.
