Ok,
I'm gonna be the smart one........Cyrix was developed by ex-workers of Texas Instruments, and Cyrix is a better answer than AMD because Cyrix took the Pentium and reversed engineered it. They weren't very good due to low clock speeds and no CPU cache, but even though AMD is still a 'rival', your teacher is right. BTW Intels, I believe, are way better...But that's just my personal opinion.
