180 watts under load for the high end 6 core sandy bridge E chips, with intel recomending that PSU makers make their PSU's deliver at least 23 amps on the secondary 12volt rail dedicated to the CPU...I wonder how high it can get once overclocked....Yikes.


Ivy bridge with it's 22nm finfet process and 30% power savings over the 32nm process sounds rather nice right about now, and some here actually wanted an 8 core version Sandy bridge E while still on the 32nm process....
I really don't believe that at all... Intel already has working I7 980x cpus on 32nm... A die shrink isn't going to make it draw more power than the previous generation. It would be more likely that Intel can either bump up the clock speeds can keep the same TDP or use similar clock speeds with a lower TDP rating.

The one thing they might be mistaken on was some of the server cpus were supposed to have configurable TDPs. So rather than set the clock speeds based on a model number, each part would change based upon the BIOS setting. Maybe then I could see some BIOS settings letting them scale up to 180W draw to maximize speed.

This is an Anand article about Ivy bridge: http://www.anandtech.com/show/4378/i...nfigurable-tdp

If they did implement that I suppose SNB-E could hit 180W for a very short period, but that would still mean they would need some pretty high OC's to be able to do that. I'd have to imagine 3.6ghz hex cores would be possible in the same TDP, so it would be well into the 4ghz range with turbo modes.
