The '''K5''' is [[AMD]]{{'}}s first [[x86]] processor to be developed entirely [[in-house]]. Introduced in March 1996, its primary competition was [[Intel|Intel's]] [[Pentium (original)|Pentium]] [[microprocessor]]. The K5 was an ambitious design, closer to a [[Pentium Pro]] than a Pentium regarding technical solutions and internal architecture. However, the final product was closer to the Pentium regarding performance, although faster clock-for-clock compared to the Pentium.
