AMD launches A-series chips with 10.5-hour battery life

AMD Fusion A-series chips go live

AMD on Tuesday formally launched its Fusion-based A-series chips and detailed their performance. The 32 nanometer chips make the expected leap in integrated graphics, which can have 400 visual effects cores and compete with some mainstream dedicated chips yet sit inside the processor itself. A move to a 32 nanometer manufacturing process not only keeps the chips relatively small at 228mm2 but can lead to as much as a 50 percent boost in battery life: AMD has promised as much as 10.5 hours.

Any A-series system can include dedicated graphics and theoretically gets up to 75 percent more performance from the move based on current Radeon HD hardware. Many of them offer dynamic clocking on individual cores and the graphics to reduce power consumption when not under a full load.

All of them can support USB 3.0 from the start and can support 3D over an HDMI 1.4 output. A new feature specific to the A-series is Steady Video, a hardware trick that can compensation for bumps and jolts that lead to rough-looking video.

The full A-series line hasn't been detailed but includes dual-core A4 processors as well as quad-core A6 and A8 chips, most of which are available in either desktop or notebook forms. Systems are shipping from HP, Acer, Toshiba, and other PC builders either today or in the near future.

    10.5 hours.. on what?

    10.5 hours on what display? what tablet? what OS? what hardware? is not the same 7 inches than 10 inches display. Is not the same to feed a lot of sensors that feeding just one, is not the same battery on the 10 inches ipad that the one in the 7 inches Galaxy.
    If they only put the processor to work wit no regular hardware, then 10.5 hours is very small amount of time.
    I definitively think AMD is following Microsoft's path on false or incomplete publicity. They compare products but they don't give you the details of the products they are putting head to head. Half true, Half results, half cheat.

    This write-up is wrong (RTFA): the chip runs for 11 hours and 1 minute on the BAPCO MobileMark® 2007 “Productivity” test:

    In testing conducted by AMD performance labs the 2011 Low Power platform reference design “Brazos” demonstrated up to 661 minutes or 11:01 and demonstrated “all-day” battery life on BAPCO MobileMark® 2007 “Productivity” test as “resting” metric and 406 minutes or 6:46 as an “active” metric using 3DMark '06. All testing performed using a 6-cell Li-Ion, 62Whr battery.

    I'm sure they couldn't ....

    come up with a better name than "A4" or "A6" ..... those were the most sensible !!! It's not like another company is using those same names in the mobile space !!!
