Am286: Manufactured Under License, But Faster
AMD’s Am286, a clone of the Intel 80286 manufactured under license, was identical to the chip from Intel, but it had a big advantage: its higher clock speed. Whereas Intel’s 286s topped out at 12.5 MHz, AMD sold 20 MHz versions. Because the 286 was more economical than the 386, whose innovations weren’t fully exploited for several years, AMD was already the value choice more than 20 years ago.
