Yeah, Haswell has EIST (stepping). With the proper Windows power settings, it will clock down to "5%" by default (actually about 800 MHz) and back up to max speed as necessary, very rapidly. Check articles on Haswell idle power consumption. It was sort of designed for mobile to begin with due to VRM on DIE.

Edit: Um yeah, refer to the post above this. Minimum processor state.

The other thing Windows does is reduce clock speed when load is very lowgDKQOr

Haswell C6 and C7 are pretty close to off. That should be all you need if you want to conserve power. But putting the cores in any off state or deep low power like C7 affects performance.

Gene i feel no difference, when cores are needed they turn on automatically, with normal browsing i dont exceed 15% of core usage.

Latencies are about 100 us longer.

Do your think you will notice a power difference of several watts (I assume a desktop)?
