PC users are running multiple, intense software applications simultaneously, increasing demand on hardware resources. In the office, PC usage has changed from data entry and word processing to e-Commerce, online collaboration and an ever-increasing need for continual security and virus protection.

The Intel Core 2 Duo processor was developed to meet all these demands.
