Does the G6950 support power gating?

[I4AT]

Couldn't really find a straightforward answer on this, anyone know?

Datasheets show C1, C3, C6 for the Core i3/i5/Pentium 6xxx series Clarkdale processors, so I'm guessing it should. Why do you ask?

Just curious, I have a G6950 on the way and it'd be nice to have the extra power savings at idle/low load. Is C6 = power gating?

C6's definition: Saves the CPU state into dedicated SRAM, and powers down the CPU to low as 0V. Has the longest wake time.

Now that doesn't mean its power gating. C6 existed on pre-power gating CPUs like Core 2. But it would be kinda weird to support power gating on Core i3/i5 and not on Pentium. It has same power usage at C6 as other CPUs so the chance is very high.

Power gating really isn't a C-state, it's a hardware design. Either you have the transistors needed to cut off voltage to parts of the chip, or you don't. Since it's the same Clarkdale die as the rest of Intel's processors, the ultimate answer is yes.

Plus if it didn't have functional power gating, AnandTech's results would not be what they are. http://www.anandtech.com/show/2972/...-pentium-g6950-core-i5-650-660-670-reviewed/8
