Intel's latest chip designs have other features to raise efficiency. Performance increases, compared with earlier models, average 7% to 13% at the same clock speed, Mr. Perlmutter says. But gaming enthusiasts are equally excited about the prospect of greater increases in clock speeds to make programs run faster.
Intel's new $999 quad-core model for high-end PCs, called the Core 2 Extreme QX9650, is being introduced at an initial clock speed of three gigahertz. But Kelt Reeves, president of gaming-PC maker Falcon Northwest, said he has been able to use a technique called overclocking to operate the chip at four gigahertz -- boosting performance by a third -- with little increase in power consumption. That suggests Intel's manufacturing process has "headroom to burn" in developing faster models later, he said.
Besides the gaming version, Intel is announcing 15 Xeon models for server systems, priced from $177 to $1,279, with clock speeds of up to 3.4 gigahertz.
