Intel rolls out quad-core processors

SAN JOSE, Calif. - Intel Corp., the world's largest computer chip maker, on Tuesday launched a family of chips with four computing engines inside a single microprocessor.
The "quad-core" processors, which boast improved performance over models with just one or two processing cores, could help the company win back market share lost to smaller rival Advanced Micro Devices Inc., analysts said. Processors with multiple cores can handle more complex jobs at once.
Intel rolled out four processors for servers under the Xeon 5300 branding, and another processor under the Core 2 Extreme series aimed at hardcore computer gamers, programmers and other people with heavy-duty computing needs.
