Power Consumption while Overclocked
For our final test, we looked at power consumption while overclocked to the same frequency - in this case, 3.33GHz. The voltages remained the same, as did the rest of the system settings.
First, at idle:
The improvement is climbing, we're at almost a 6% decrease in power consumption at idle thanks to the new core.
Under load, the trend continues:

Both chips used the same VID surprisingly enough, that's part of what made this test so easy. I have seen differing results at 8x vs. 9x multipliers, but it didn't seem to make a huge difference when I tried it with these chips. I'll keep playing around with them though.Take care,

Hi Anand!Could you please mention what the VID was, if it was identical between chips then it sounds like it was over 1.3v?
You probably had already seen http://forums.anandtech.com/messageview.aspx?catid...">http://forums.anandtech.com/messageview.aspx?catid... but I thought it was interesting that some of the VIDs are so low. My own sample is also 1.200v and seems to OC well enough, a partially corrupted OS notwithstanding anyway.
My Pentium M barely operates stable at 2.13GHz using 1.18v and it's obviously single core, so it just sounds odd that a 2.4Ghz Quadcore could have an even lower VID than 1.18v even with the 90nm -> 65nm difference. Maybe that is just me though!

It was 1.20V on both chips I believe.Take care,

Woot!
