Intel Telling Pork Pies....

    In an article here:
    http://www.computerworld.com/s/arti...swell_gets_massive_graphics_performance_boost
    Computerworld quote Intel as saying, and I quote from the site:

    "The chip maker has said the battery life of ultrabooks will double with the
    new fourth-generation Core chips."

    What utter rubbish! Considering that, in current 'Ultrabooks' the display is
    the single sub-system responsible for the greatest power draw, and the CPU
    draws on average 35% it's physically impossible for a simple CPU upgrade to
    double the battery life.

    If it's twice as efficient, as they seem to claim, then the CPU will only
    draw half as much - meaning a reduction in power draw by 17.5% - about a 20%
    increase in battery life. That's a far cry from a 100% increase, Intel must
    think that we're all morons. :-/

  2. The article was not about a simple CPU upgrade.
    Maybe they just hope we can read.

    Yeah, it is. Ivy Bridge to Haswell. Both have GPUs built in.
    Indeed, and not 'between the lines'. They're saying the Haswell will allow
    '4K' playback on a laptop but don't mention no laptops in existance have 4K
    displays or how much power it would take to run one.

    They say: "A 28-watt Core i7-4558U doubles the graphics performance of the
    17-watt Ivy Bridge chip." Duh! It uses nearly twice the power! *And* it's
    next-gen - it'd be a disaster if it *didn't* double the graphics
    performance!

    (Since both major /CPU/ manufacturers have been heading in the direction of
    /APUs/ for a couple of years now.)
