Intel expects to ship its first processor with four cores in the early part of 2007.
News of an impending four-core product comes as Intel said it expected to sell about 60 million dual-core chips this year.
The new four-core chip is code named Clovertown and bundles four processors on a single platform.
Such a solution uses less power than single-core designs and allows machines to process data more quickly and run more applications at the same time.
Clovertown will be aimed at servers that run enterprise networks and host websites.
Intel said the chip will be sold in servers with sockets for two four-core processors, which means the servers could have as many as eight cores for rapidly processing data.
Intel has so far not said whether the four-core product will be four processors on a single piece of silicon or whether it will be two dual-core processors joined together.
A single silicon wafer product is more power efficient but harder to manufacture.
