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.

    CPU perf pretty much as expected,GPU perf somewhat dissapointing ,i thought they'll at least aim to match Llano but i guess it is ok for 1MP laptops screens if mobile parts perform close enough (and a couple of big ifs when it comes to image quality and drivers).
    Any opinions yet about QuickSync encoding quality?

    And we should remark that's comparing 2600 with 3700 which have different cpu too.
    Other benchmarks had significantly better results on 3700 than 2600.

    So Anand, how you know that difference is not attributable to the CPU and not to some gpu improvement?

    You are not being serious, are you? The CPU gets 10% in CPU sensitive benchmarks and GPU gained 40-60%. Even taking out 10%, its still 30-50%, which btw isn't true as games aren't very sensitive to CPU changes as applications do. Reply

    Look at crisys or metro benchmarks and tell me where you find that improvement, at least more than what you find in cpu difference. Reply

    I've tried it on some HD clips at a local TV station and on a big screen it really sucked.It's way behind AMD.We used aHP EliteBook 8460P laptop. Reply

    At least AMD's products are HD capable. Reply

    My 5 year old laptop with a shared ram gpu is "HD capable". GTFO noob. Reply

    Billions in R&D, double the MSRP, half the power and yet it still can't play Crysis better than Llano, which will be replaced by Trinity in a few weeks. What a crying shame. Reply

    Not playing Crysis sounds like a good thing to me. Reply

    Source or gtfo. Apple got the stock HD 3000, why would this be different? Reply
