AMD's New Low-Power CPUs

Posted by timothy on from the you-fools-you're-helping-people dept.

illumina+us writes "AMD has released a new family of CPUs targeted at the portable computing market. The new CPUs, collectively named Alchemy, consume less than 1Watt of power. The CPUs have already been named the CPU of choice for Tivo's new Tivo-To-Go technology and are powerful enugh to run DivX, WMV9, and MPEG. The AU1550 consumes just 0.5 Watts at 400 MHz and the AU1100 consumes 0.25 at the same clock speed. These processors consume so little energy they don't even need a heatsink."

  1. FLOPS per Watt? by DumbSwede · · Score: 5, Insightful
    It'd be nice to see how these stack up in FLOPS per Watt.

    Perhaps these are the chips Supercomputer manufactures should be building machines with. Sounds to be low in cost to build AND low in cost to run.

    until we can get that kind of low power consumption on desktop chips? is there something inherent in desktop applications that prevent some chip maker from making a really low-power, high-performance (~1GHz) processor?

    It seems to me that its about high efficiency, not low power. Merely having a low power chip does not help a supercomputer if you need that many more of them to get the same performance.
