Intel Claims Haswell Architecture Offers 50% Longer Battery Life vs. Ivy Bridge

Posted by Soulskill on from the just-don't-use-a-screen-or-any-other-hardware dept.

MojoKid writes "As with any major CPU microarchitecture launch, one can expect the usual 10~15% performance gains, but Intel apparently has put its efficiency focus into overdrive. Haswell should provide 2x the graphics performance, and it's designed to be as power efficient as possible. In addition, the company has further gone on to state that Haswell should enable a 50% battery-life increase over last year's Ivy Bridge. There are a couple of reasons why Haswell is so energy-efficient versus the previous generation, but the major reason is moving the CPU voltage regulator off of the motherboard and into the CPU package, creating a Fully Integrated Voltage Regulator, or FIVR. This is a far more efficient design and with the use of 'enhanced' tri-gate transistors, current leakage has been reduced by about 2x — 3x versus Ivy Bridge."

    I'd be interested to know what phone you have, that uses an Intel Ivy Bridge server/desktop/laptop processor.

    Is this seriously 50% increase in battery life? Or just 50% reduction in power usage by CPU? The article wasn't clear on this. I'm assuming the power usage thing.
