Introducing the Core Micro-Architecture

As expected, Justin Rattner announced the official name of Intel's next-generation micro-architecture: Core.

All of the Core based products will be based on Intel's 65nm manufacturing process, which we've already seen with the 65nm Core Duo and Core Solo based microprocessors. Intel claims that their 65nm manufacturing process offers 20% faster switching and 30% lower power.

Rattner also mentioned that by the middle of 2007 Intel would begin their transition to a 45nm manufacturing process.

    What do I need to do so that anandtech.com will let me see the pictures when I'm reading its articles? :-( Reply

    I've found that the pictures load as 1x1 blank GIFs in Opera but appear fine in IE. That really sucks. Reply

    Anand says that SSE will execute in a single cycle but I think Intel really meant that SSE will have single cycle throughput, not latency. Notice that in the slide Intel simply writes "single cycle SSE". SSE instructions (except some of the really easy ones) are currently broken down from 128bits -> 2x64bit instructions to actually execute. This has long been the biggest weak point of SSE.

    I expect latency to be 5cycles for SSE FP multiply (it's currently 6). I expect throughput to be 1 cycle for SSE FP multiply (it's currently 2). So instruction throughput will theoretically double.

    You are quite correct, Intel just clarified this point to us and I've updated the article. Thanks for the pointer :)

    Take care,

    Do all SSE instructions execute in the same number of cycles?

    This crazy projections are always more exciting when they come from Intel because they do have a track record of NOT producing vaporware.

    On the other hand their performance figures are always way optimistic.

    If you look at the middle ground Conroe will probably be a bit faster than X2 per clock cycle. We'll see if they can ramp up the clockspeeds for release...

    "While we'll get a better idea of performance of Conroe, Merom and Woodcrest later today, Rattner did whet our appetites"

    Is that a typo or a reference (inside joke?) about performance numbers....

    That's the proper use for the word.
    I suppose what he's trying to say is they're satisfied with the info disclosed at the time.

    Whet means sharpen, right. Means becoming eager for more information, I suppose Reply

    same here. images arent loading
    hope conroe kicks ass, my next powermac will have it
