...The first chip, the Intel Core 2 Extreme quad-core processor, will be available in November. Intel says it will deliver a 70 percent performance improvement over Intel's current chips, which have one or two computing cores. The new chip is aimed at gamers, programmers and other people with heavy-duty computing needs.

For general consumers, Intel will ship a quad-core chip starting in the first quarter of 2007. For businesses, Intel will begin shipping four-core server chips later this year. A low-energy, quad chip for servers will be launched early next year, the company said Tuesday.
