Intel Core i7-6700 Socket 1151, SR2L2, 3,4GHz, 4core, 65W TDP

Intel® Hyper-Threading technology enables two processing threads per physical core. Applications with many threads can complete more tasks in parallel and finish tasks sooner.
Idle states (C states) are used to save power when the processor is idle. C0 is the operating state, i.e. the CPU is performing useful tasks. C1 is the first idle state, C2 the second, and so on, with more power-saving actions performed for higher C-state numbers.

Advanced Intel SpeedStep® Technology is an advanced functionality for the combination of high performance with the lowest possible power consumption needed on mobile devices. Traditional Intel SpeedStep® Technology simultaneously switches the voltage and frequency between high and low values depending on the processor load. Enhanced Intel SpeedStep® Technology builds on this architecture and uses design strategies such as separation between voltage and frequency changes, as well as clock partitioning and recovery.
