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 gamers don't spend money on the I7 lineup, prefering to buy the Core i5 series and invest the extra money into more GPU. Reply

    It's not only the extra money.. Apparently the 2500K does better in a fair number of games over the 2600K (in part.. i think due to Hyper Threading) and the graphs seem to support that (altho maybe not for the reason I mentioned)

    Looking at the 3700 series though it beats out both the 2500K and 2600K so I think that one is going to be of special interest to gamers.. moving forward.

    I'm afraid the next Haswell will be Tock- Reply

    Why ?

    If the statement "the significant gains we're seeing here with Ivy will pale in comparison to what Haswell provides" is true then I'm looking forward to Haswell very much. I'll finally be able to dump discrete GPU as I only use relatively mdoest dislay resolutions, and instead pour the money into even quieter cooling solution. Silence, sweet silence :)

    Nice to see AMD winning where it actually matters for most consumer applications. Reply

    You crack me up... that was truly a funny response.
    Seriously though, Llano isn't that bad for a generic/cheap build. I did pick one up to build a machine for my mom. The mobo and the proc. were justified by the price. I knew it wouldn't be powerful, but it's fairly energy efficient, has decent graphics and the money I saved went toward the ssd. Most people I build/fix computers for, don't come close to using them to their potential, so price becomes the biggest factor. Would I buy one for myself? No, I'll stick with the i7 I currently have and when I build my next machine, it looks like it'll be an Intel also.

    Thanks. :)

    I quite agree, Llano is awesome for what it does and provides an excellent platform for most users.

    I'm just tired of the assumption that GPU grunt is more powerful than CPU.

    It's true that most of my friends and family would be perfectly happy with the GPU muscle in a Llano chip. That said, they'd also be perfectly happy with the iGPU in something like a i3 2100.

    As for myself I'm using an i7 2600K, running at stock, but then I have somewhat different requirements.

    I'd not hesitate to recommend either Llano or Intel chips with iGPU solutions, it all depends on the person really.

    ...'GPU grunt is more important that CPU'... would probably read better, looking back.

    Ah well, you get the point I'm sure.
