Sean Maloney, Intel’s newly appointed president of Intel China, plans to deliver a keynote speech at the Computex trade show in Taiwan next week where he will unveil a heavy-duty effort to steer Intel into the production of low-power microprocessors.

Most of Intel’s mainstream desktop chips target power consumption of about 40 watts or so. That allows for very fast microprocessor performance, but such a chip generates enough heat that it can’t be so easily used in a laptop and has no chance of making it into a tablet or smartphone. Now, Intel plans to target mainstream chips that consume about 15 watts.

The company has already been moving in this direction for a number of years. Intel recently announced a new manufacturing innovation dubbed Tri-Gate transistors that will allow it to use lower power and smaller circuits in its 22 nanometer microprocessors. (Intel’s current Sandy Bridge chips use 32-nanometer manufacturing; the smaller the number, the faster, lower power, and lower cost.) At its recent annual investor meeting, Intel showed a working 22-nanometer microprocessor code-named Ivy Bridge that is one of the flagship chips for this new low-power strategy. The Tri-Gate transistors take advantage of three dimensions and allow for a 50 percent power reduction at a given level of performance with only a 2 to 3 percent increase in costs. Ivy Bridge will be followed by a chip code-named Haswell that will represent the fruition of Intel’s efforts to reduce the average wattage of its mainstream chips.
