  15. 8.5 Enhanced turbo boost technology (1) 8.5 Enhanced turbo boost technology[64] Innovative concept of the 2.0 generation Turbo Boost technology The concept utilizes the real temperature response of processors to power changes in order to increase the extent of overclocking [64] Thermal capacitance Cooler

  16. 8.5 Enhanced turbo boost technology (2) Concept: Use thermal energy budget accumulated during idle periods to push the core beyond the TDP for short periods of time (e.g. for 20 sec). Multiple algorithms manage in parallel current, power and die temperature. [64]

  17. 8.5 Enhanced turbo boost technology (3) Intelligent power sharing between the cores and the integrated graphics[64]
