The latest Sony notebook that will arrive this summer will be the first to employ “hybrid graphics”. It will intelligently switch between using Nvidia and Intel on-board GPU. When laptop is plugged in, power hungry high performance Nvidia /ATI will be used, and Intel 4500 series integrated graphics when laptop is on battery. The 13-inch Sony Vaio Z570, will use an Intel P9500 (2.53GHz) processor that has power envelope of only 25 watts compared with the 35 watts used by the current Intel Mobile processor. The laptop also comes with 320GB hard disk drive, 3GB of DDR3 RAM, built in Wi-Fi and EVDO, all accessible through 13.1-inch screen. The Z570 only weighs 3.3 pounds making it practical to carry everywhere. Price has not been confirmed, but it will be in the range of $2,500 to $3,500 for Blu-Ray equipped model.
