Power Consumption
Intel isn't really exploiting 22nm for significantly higher default or max turbo frequencies. While it does seem like you'll hit turbo frequencies more often with Ivy, most of what 22nm offers will be realized as power savings.
At idle, all cores are already power gated so there's not much more Ivy Bridge can offer. We see savings of a couple of watts at most over the 2600K but otherwise it's nothing significant. In notebooks I'd expect to see implementations of DDR3L help keep power consumption down, but at idle there's really not much that can be done.
Under load however the power savings are significant. The Core i7 3770K pulls 27 fewer watts while delivering better performance than the 2600K. Again, translating this to what you can expect in notebooks I'd say that peak battery life likely won't be affected, but battery life under load will be better with Ivy.

Except the quality is the same as competing AMD products if not worse because of driver issues, but you lose 20-30% performance in every scenario versus the last gen Llano APU. The facts are in this very review.Articuno - Tuesday, March 6, 2012 - link
Sure sounds like Bulldozer at this point, doesn't it?""It's just a driver issue, AMD/Intel will fix it!"
"It's just the review units sent out, AMD/Intel will have a BIOS update at the official release that improves performance!"
"If you overclock it to hell and back, it can almost sort of maybe compete with Intel/AMD!"
"Oh look, there's a new update out that improves performance! Sure it's only 1% performance, applicable in only certain scenarios, but it's better than nothing!"

Aside from that NOT being what I said at all... you do realize you justified the reasoning in your post, right? They're bribing Intel. That doesn't mean they did nothing wrong, it's a BRIBE. Besides, Intel is just as guilty as Microsoft of OEM threatening and hand-holding in the 90s.Makaveli - Tuesday, March 6, 2012 - link
Who the hell is this Sans2212 troll.Dude please do all of us a favour on this site and STFU.
90% of the people reading this site know more than you.
Take your bad english GTFO.
+1 for ban!

If you Google his handle you'll find out he's been doing this for a while now (and that he's probably Japanese, which would explain the poor English).+2 for ban.

I don't think he's serious....reading come of his comments...nobody with a human brain can reason like that...If he IS serious, opens up the possbility of creating an online zoo exhibit out of him...prod him with an AMD logo and he'll roar, shout, roll and snap :)

Poes law in full swing. The morons are indistinguishable from the people trying to look like them.silverblue - Wednesday, March 7, 2012 - link
Awww I missed it... I usually like reading his rants, especially his obsession with "amd craps". He filled the void SiliconDoc vacated.Jamahl - Tuesday, March 6, 2012 - link
Wake me up when intel does something interesting again.MJG79 - Tuesday, March 6, 2012 - link
2009 - $35B in revenue2010 - $44B (1st $40B year)
2011 - $54B (1st $50B year)
$20B revenue growth in 2 years
You wake me up when there is competition again.
