Any guesses as to % gain from Ivy Bridge?

    The most powerful 15" MBP (2.5ghz i7) is scoring about 10600-10700 in the 32-bit geekbench test. What would you guess it's Ivy Bridge equivalent would score? 12000 or so?

    Intel states up to 20% performance gains but to be honest in the real world tests I've seen, its more like 5% to 10%; if that. :/

    I doubt real-world CPU boost will be any higher than 10%.

    The real benefit of Ivy Bridge is not its performance muscle, but rather what comes along with it:

    • USB 3.0
    • Reported 20% longer battery life
    • Cooler heat outputs (less fan noise)
    • HD 4000 GPU (reported to be a 30% better than current HD 3000)

    Sandy Bridge is powerful enough already, I dont think we need more CPU power. So I'm glad to see that Ivy Bridge will shift the upgrade focus to other sore points that needed some love already (GPU, outdated USB 2.0, etc).

    The processors that Apple are likely to use (3610QM, 3720QM, 3820QM - ref) are all clocked about 8% faster than the current offerings. Given there's no architectural improvements on the CPU side, you should see an 8% performance increase.

    The GPU part of Ivy Bridge (HD 4000) is a large improvement over Sandy Bridge's HD 3000, but being unfamiliar with the Geekbench test I am unsure how CPUs and GPUs are weighted?

    Geekbench doesn't weigh GPU performance. It score based on CPU and memory.

    Uh, false.

    10-20% from architectural. Increase in clock speed. Decrease in heat and power consumption.

    False again. Only the GPU is faster architecturally. The CPU is 1-3% faster clock for clock on the same ram speeds. The rest is all clock speed and more aggressive turbo.
    The decrease in heat and power consumption is not actually apparent in notebookcheck's tests at the standard clock speeds. It seems worse at a higher performance level yet still.

    Uh, False. Notebookcheck? Sorry, check a real source:

    Goes as high as 15% improvements. Clock speeds are about the same.

    Will people who don't know what they're talking about please stop posting?

    Ivy Bridge is around 20% faster clock for clock. A mid-spec Ivy Bridge CPU is already beating the best high end Sandy Bridge CPU.

    And power consumption is lower while offering increased performance.

    Im not sure where you pull your numbers from, but its not a 20% increase, not even close. Across the board, in real world i would say about 8% or so. 20% is just not even close to the truth.

    The big gain here is the HD4000 compared to HD3000. Too bad that Intel suck when it comes to good drivers for it though.
