The K5 is AMD’s first x86 processor to be developed entirely in-house. Introduced March 27, 1996, its primary competition was Intel’s Pentium microprocessor. The K5 was an ambitious design, closer to a Pentium Pro internally than a Pentium. However, the final product was closer to the Pentium regarding performance, although faster clock-for-clock compared to the Pentium. The “K” in the name K5 stood for Kryptonite. AMD, being an underdog compared to Intel, hoped the K5 be the undoing for the Superman-like Intel.
