Laptops with Ivy Bridge will be engineered for CPUs, graphics accelerators, memory and screens to consume less power, the chip maker said at the Intel Developer Forum (IDF) in San Francisco.

Laptops with Core processors based on Ivy Bridge will become available in the first half of next year. CPU and graphics processor will be integrated on a single chip, and deliver double the performance-per-watt compared to Core processors based on the Sandy Bridge microarchitecture, which are available in PCs today. Intel outlined further details about the Ivy Bridge microarchitecture in multiple sessions at IDF.

Besides making on-chip improvements, Intel is enlisting the help of companies such as LG Display, which at IDF showed the new Shuriken display that can refresh on its own. By leaving the CPU and other components idle, the net 450 milliwatts of power savings can add up to an hour to a laptop's battery life.

"When I've got a static system ... the CPU is asleep and the self-refresh is working in the screen itself," said Mooly Eden, vice president and general manager of Intel's PC client group.

In addition, Ivy Bridge will support low-power DDR3 memory, which will consume less power than standard DDR3 memory used in most laptops today, said Varghese George, senior principal engineer.
