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.

Look at the chart. Nehalem (i920) was a tock. Replyjust4U - Thursday, March 08, 2012 - link
I have to disagree with you on the i920 being such a huge leap. As someone who goes thru virtually every cpu line up for AMD/Intel I'd have to say the C2D (or quad) 6x series was the biggest leap forward in the past decade. Before that it was the A64 and X2 variants (altho.. we didn't get alot of use out of those secondary cores) ReplyIntelUser2000 - Thursday, March 08, 2012 - link
LOL, this must be the most hilarious argument I've heard in a while.How do you relate 30+ % graphics gain as being ALL CPU? Don't be ridiculous, and that's an understatement. Reply

Are low-res testing really relevant for graphics?Most players play at 1920x1080 or higher.
1368x720 or 1680x1050 does not seem relevant to me at all for most people, especially those purchasing a computer with this processor. Reply

Most players who game at 1920x1080 also have graphics cards that cost more than $100. That's not what this was testing. Replygeekfool - Thursday, March 08, 2012 - link
I intend to get a 1900x1200 monitor to replace a 1024x768 but don't generally game with anything more sophisticated than OpenTTD...I figure a 7750 Radeon will be enough of a graphics card. ReplyYojimbo - Thursday, March 08, 2012 - link
uhh.. i don't think that's true. graphics intensive applications are not the only ones that benefit from fast CPUs. Replykrumme - Thursday, March 08, 2012 - link
Where does Charlie claim to be biased?But i agree, this sacred, aura, "this is not sanctioned by Intel" is a pain to read. It makes thesse articles a little bit difficult to start reading :)
But how profitable, and how good a business do you have if you dont have "good conections"? - charlie uses his for underhand information, anand his to get info before the others. Its very obvious for us to interprete Anands article because we know the obvious, - it have to be profitable for both anand and Intel. But what about Charlie, what is the motives for the people leaking info to him? - its not quite so obvious and transparrent. Reply

"Sure, he was comparing Intel graphics to Intel graphics, except he wasn't, because he himself threw Llano in there to compare."By the same token, if he had not included Llano results people would be wondering where they were and complaining that they weren't included. Puts Anand in a catch 22 when deciding whether or not to include Llano.
There is validity to the complaint about the numbers being incorrect. Those should be looked at and corrected. Glossing over the results and no mention of Llano being more capable, again, this was mainly to compare Intel v Intel in a preview of their new chip and improvements they've made since last gen. Sure, he could've been more thorough with the AMD v Intel side, but that's not really what this article was about. We could also go to a steakhouse and complain there's not a large vegetarian meal selection too. Reply

it doesn't really matter if the igp isn't that great most people don't buy them for their graphics power.I get the feeling that maybe intel is just putting them out there to keep it's base solid against AMD,Not that it needs it and i'm an amd fan. i found something the other day that will possibly change how tomorrows processors will use light instead of electricity.http://scitechdaily.com/penn-researchers-build-a-c...
