    Intel x86 cpu @ 2 GHz and only consumes 2 W

    Intel will apparently be showing at the International Solid-State Circuits Conference ISSCC in Feb.

    Its supposed to be a x86 chip which runs at 2 GHz and consumes only 2 W.

    International Solid State Circuits Conference, Feb 3-8, 2008



    13.1 A Sub-1W to 2W Low-Power IA Processor for Mobile Internet Devices and
    Ultra-Mobile PCs in 45nm High-К Metal-Gate CMOS

    A 47M transistor, 25mm2, sub-2W IA processor designed for mobile internet devices is
    presented. It features a 2-issue, in-order pipeline with 32KB iL1 and 24KB dL1 caches,
    integer and floating point execution units, x86 front end, a 512KB L2 cache and a
    533MT/s front-side bus. The design is manufactured in 9M 45nm High-К metal-gate
    CMOS and housed in a 441-ball μFCBGA package.
    13.2 A 45nm 3.5G Baseband-and-Multimedia-Application

    Also some new itanium

    4.6 A 65nm 2-Billion-Transistor Quad-Core Itanium® Processor

    An Itanium® processor is implemented in 8M 65nm CMOS and measures
    21.5×32.5mm2. The processor has four dual-threaded cores, a system interface and
    30MB of cache. Quickpath high-speed links enable peak processor-to-processor
    bandwidth of 96GB/s and peak memory bandwidth of 34GB/s.

    Looks rather suitable for a Eee PC. Depending how much they charge for it.

    The 2W part looks like a stonkingly good prospect for an ultramobile - I thought "Eee" as well; it just seems a completely natural fit.

    Re: Intel x86 cpu @ 2 GHz and only consumes 2 W

    2Ghz doesn't mean anything if we don't know the IPC information.
    It might be slower than a 250Mhz Merom/Penryn which makes the 2W point moot.
    Merom can already achieve <10W at 1Ghz, and even lower power consumption with the ULV models.

    Having not bothered to read the link, it sounds like silverthorne in which case it has similar IPC to the early Pentium-M CPU's and supports all of the same instructions.

    "Intel promises that Silverthorne will offer performance comparable to its 90nm Pentium-M from 2004."

    Anandtech did a piece on this here.
