Biography | Pat Gelsinger — The Campus Where He Architected the 486

People remember the 486 as a Pentium prequel announced at a trade show.

The design was run from Intel's Santa Clara campus by an architect still in his twenties.

After the 386, where Gelsinger had been design engineer number four, he became chief architect and design manager of the 80486.

The chip was announced on 10 April 1989 at Spring Comdex. First silicon had come back from the fab on 20 March.

It was the first x86 processor with more than a million transistors, an on-chip cache, and an integrated floating-point unit.

A 2000 Morning Call profile, written when he was thirty-eight and running Intel's desktop products group, treated that assignment as the fact that defined him.

The announcement hall in Chicago is a separate pin. This one is the campus where the work was done, now gathered around the Robert Noyce Building at 2200 Mission College Boulevard.

He was named Intel's youngest vice president at thirty-two. In 2001 he became the company's first chief technology officer.

USB and early Wi-Fi work sat in that same stretch of titles. The 486 is the one with a date and a product name a visitor already knows.

He left Intel in September 2009 for EMC, then VMware. The architecture job is what made the later return as chief executive sound like a homecoming rather than a hire.
