Below picture is from the wikipediaTheK6microprocessor was launched byAMDin 1997. The main advantage of this particular microprocessor is that it was designed to fit into existing desktop designs forPentium-brandedCPUs. It was marketed as a product that could perform as well as itsIntelPentium IIequivalent but at a significantly lower price. The K6 had a considerable impact on the PC market and presented Intel with serious competition.

The AMD K6 is manufactured byAMD, which superseded theK5.

The AMD K6 is based on the Nx686 microprocessor thatNexGenwas designing when it was acquired by AMD. Despite the name implying a design evolving from theK5, it is in fact a totally different design that was created by the NexGen team, including chief processor architect Greg Favor,[1][2]and adapted after the AMD purchase. The K6 processor included a response dynamic instruction reordering mechanism,MMXinstructions, and a floating-point unit (FPU). It was also madepin-compatiblewith Intel's Pentium, enabling it to be used in the widely available "Socket 7"-based motherboards. Like theAMD K5, Nx586, and Nx686 before it, the K6 translated x86 instructions on the fly into dynamic buffered sequences ofmicro-operations. A later variation of the K6 CPU,K6-2, addedfloating-point-based SIMD instructions, called3DNow!.
