Dell Inc, the world's second-largest personal computer maker, said on Wednesday it started selling machines with microchips from Intel Corp that have four processing cores, delivering faster performance and better energy efficiency.
Dell said it was offering Intel's quad-core version of its Xeon chip for server computers that run business networks, and a quad-core version of the Core 2 Extreme chip for high-end desktop computers used for heavy-duty computing like graphics and 3-D modeling.
