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.

Power Consumption - Idle

Power Consumption - Load (x264 HD 3.03 2nd Pass)

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.

    Most players who game at 1920x1080 also have graphics cards that cost more than $100. That's not what this was testing. Reply

    Man you won't believe the difference :)

    Get an SSD with that.

    You're going to seriously start wondering why you didn't upgrade sooner. Just don't hurt yourself too much when you slap your own face. Tech has advanced astronomically in the last 10 years.

    Heck, I'm pretty sure the iPad 2 is faster than your Northwood Pentium 4.

    uhh.. i don't think that's true. graphics intensive applications are not the only ones that benefit from fast CPUs. Reply

    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.

    "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.

    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.

    ...hi everybody.

    I'm an electrical engineer, doing intensive "spice" simulations.
    I want to know if, as it requires a lot of floating point calculations, does it worth to wait for Ivy Bridge instead of buying right now a laptop with a quadcore Sandy Bridge? I expected Ivy Bridge for March and i've been waiting since last december :(.
    To buy now would be very comfortable, as i'm in the simulaiton phase of my project. To buy later, I believe, would make more sense in term of pure performances . But how much sense is the question....

    Thanks for sharing

    PS (another thing is also theuse of 1600 memory instead of 1333, which might be doing it for another software I use)

    I wonder how IvyBridge perform in term offloating point calculations as I do intensive electrical simulations.
    I urgently need an upgrade and would definitely go for a Ivy Bridge. But I've been waiting a long time now and Ivy Bridge may again been delayed.
    Does anyone have an advice about it?

    Thanks for sharing.

    How about OC? Info please?
    Is hard to decide wait until IB or get SB now because the how well IB can OC.
