Intel wants to make Ivy Bridge more power efficient -

Chipzilla's latest cunning plan is to slash Ivy Bridge's power consumption to make Ultrabooks more attractive by reducing the amount of juice they need.

According to CNET, this is not a future design, but may result in the current Ivy Bridge chip getting throttled to reduce the amount of juice it uses.

Intel's most power efficient Ivy Bridge chips today are used in Windows Ultrabooks and Apple's MacBook Air and weigh in at 17 watts.

This makes them look energy hungry when it comes to other chips which are expected to function in a mobile world. The power consumption on ARM chips is typically rated at below two watts and devices with these chips offer all-day battery life. But by reducing the power consumption within Ivy Bridge PC makers could theoretically use the chip in tablets.

Microsoft has indicated that it will use an Ivy Bridge Core i5 chip in its Surface Pro tablet, because of the performance advantages. However, manufacturers want to see more power reductions before they take such a bold move.

Windows 8 tablets and tablet-like products, like HP's Envy x2, use Intel's Z2760 system-on-a-chip. This is power efficient for Intel but falls far short of Ivy Bridge's performance.

The company said in September that its next generation of chips, codenamed Haswell, will be rated as low as 10 watts, slashing power consumption by about 41 percent. And later Haswell chips will be even more power efficient.

CNET thinks that the new range of low powered Ivy Bridge chips will be out sometime next year.
