The INQ guide to Intel model numbers

PUZZLED BY the numbers Intel now uses, and will use in the future? We know we sometimes are. Here's the INQUIRER guide to Intel model numbers, which you may find useful if you're trying to figure out the cache, front side bus speed and frequency of present and future CPUs from the company.

All future Intel desktop and notebook microprocessors will use these model numbers, but the company has no plans to extend this system to its server microprocessors.

Most of the CPUs in the crib sheet below use or will use Intel's 90 nanometre "Prescott" technology, or in the case of the notebook chips its 90 nanometre "Dothan" tech, although a few of the previous generation of Banias notebook chips are still in production. Intel also has a "legacy" roadmap for Northwood cores, using the previous 130 nanometre technology, but is moving at high speed to phase these out.

For model numbers that haven't yet been introduced, see our Intel roadmap page, which you can find here. µ
