Turbo Core Energy Efficiency Feature Coming in AMD Phenom II

AMD is expected to add more energy efficiency to its forthcoming processors, the Phenom II, with Turbo-Core -- technology designed to reduce the power in inactive cores and increase power in active ones. The technology increases energy efficiency while improving performance -- features that pit AMD against its chief rival Intel.

Intel earlier this year brought its Turbo Boost technology to its Core i7 desktop processors. The technology powers down idle cores in a processor and moving some of that power over to active cores, essentially overclocking them and improving the performance of the chip. Now rival Advanced Micro Devices is reportedly ready to add a similar power-optimizing feature to its upcoming six-core Phenom II X6 "Thuban" line of desktop chips.
