AMD Unveils Turbo Core Processor Technology

From PC World: AMD has released a bit more information on its upcoming six-core Phenom II X6 processor (codenamed Thuban) and revealing its take on automated overclocking, dubbed Turbo Core. We've covered Intel's Turbo Boost feature at length, and AMD's Turbo Core follows many of the same principles.

The general idea behind Turbo Core (and Turbo Boost) is that many applications don't take full advantage of multicore processors, leaving quite a bit of wasted potential as unused cores lie dormant. Turbo Core and Turbo Boost propose to fill in that gap, increasing performance of those cores that are in use, while maintaining the chip's particular power and heat thresholds. In the upcoming Phenom II X6, the Turbo Core feature will kick in when three or more cores aren't being used, automatically overclocking the cores that aren't idle up to a reported 500MHz.

Better still, CPUs based on the Thuban platform will work with existing socket AM3 and AM2+ motherboards (after a BIOS update), including motherboards based on the new 890GX chipset that we recently reviewed. This backwards compatibility promises to reduce upgrade costs. Six-core Thuban chips will reportedly be available in the second quarter of this year, with quad-core chips based on the new platform to follow.

While AMD has sold six-core Opteron server processors for some time, the Phenom II X6 is aimed strictly at the consumer market, with a less than subtle nod towards enthusiast gamers, and workstations.

Whether or not AMD's new Thuban platform takes the performance crown remains to be seen. AMD has yet to develop a response Intel's Hyper-Threading feature, which allows a single core to process a pair of threads simultaneously, effectively giving a six-core processor twelve available threads for multi-threaded applications to take advantage of.
