Intel Pentium Overdrive 133

A quite uncommon processor: an Overdrive for socket 4 systems. The first Pentium's used socket 4 and ran at 60MHz or 66MHz. Socket 4 had a short life-span because Intel quickly shifted to socket 5 which operated with a lower voltage (3,3V instead of 5V).

For those who invested a lot in the first socket 4, the so called 'upgrade-path' came to an end quickly as there we're no faster parts available than 66MHz. That was, until this Pentium Overdrive came into existence. Nevertheless it was an expensive upgrade but going from 60/66MHz to 120 or 133MHz (this Overdrive is also officially rated for 120MHz) was a nice boost back in '96.
