All Pentium 4 Models

Northwood

Contents

After Williamette came Northwood core. This core is around 60% smaller than Williamette core because of its 0.13 µm manufacturing process. Northwood core can be found using 512 KB or 2 MB L2 cache, external bus running at 400 MHz, 533 MHz or 800 MHz (100 MHz, 133 MHz or 200 MHz transferring four data per clock cycle, respectively), SS2 instructions support and built with 55 million transistors, using an area of 131 mm2. The metal alloy used on the transistor interconnections is copper.

Copper is a better conductor than aluminum and it is softer, allowing the construction of smaller connections between the transistors.
