"Intel's new line of Celeron CPU's are based on the older 0.18 micron Williamette core that was originally released two years ago and not the newer 0.13 micron Northwood core. The reason behind this is that Intel still has a vast 0.18 micron manufacturing process up and running, and it only makes sense for them to keep that operational while Intel is slowly moving everything down to 0.13 micron. Now that we know the new Celeron's are based on the Pentium 4 architecture, how are they different from their more expensive bretheren? Actually the only difference between a Pentium 4 Williamette and the new Celeron Williamette is the amount of L2 cache."
