Intel’s 4th Generation Core series processors have been out for a couple weeks and we have had a chance to better look at Haswell’s C6/C7 low-power states. This is a power saving feature that will help reduce temperatures and lower power consumption, but sadly most motherboard vendors have chosen to disable C6/C7 by default in the BIOS. Read on to see what happens when we enable it on the Intel Desktop Board DZ87KLT-75K with the Core i7-4770K processor

Quote: "On our Windows 8 test platform we were able to quickly see the benefits of running with the C6 and C7 power states enabled. We found that with C6/C7 disabled that the system would idle between 23.7 and 24.1 Watts, but with them enabled we were seeing between 20.5 to 21.2 Watts. Both numbers are impressive as you have to keep in mind that the whole system is being measures here with a Kill-A-Watt power meter at the wall outlet..."
