Dynamic overclocking of CPUs, or TurboMode, is a feature recently introduced on all x86 multi-core chips. It leverages thermal and power headroom from idle execution resources to overclock active cores to increase performance. TurboMode can accelerate CPU-bound applications at the cost of additional power consumption. Nevertheless, naive use of TurboMode can significantly increase power consumption without increasing performance. Thus far, there is no strategy for managing TurboMode to optimize… CONTINUE READING
