These processors introduced a number of enhancements including support for [[Super Socket 7]] with bus speeds of up to 100 MHz and {{x86|3DNow!}} [[SIMD]] extension. Due to its ability to extend the life of [[Socket 7]]-based systems and being relatively cheap, the K6-2 family of processors became a highly successful series with some models continued to be manufactured well past {{amd|K6-III}} and {{amd|K7}} introduction. |

Following [[AMD]]'s acquisition of [[NexGen]] in [[1995]] and the success from the release of {{amd|K6}} (a rebranding of NegGen's {{nexgen|Nx686}}), AMD had the financial means of developing the [[microarchitecture]] further. With the '''K6-2''' family, AMD took the much safer and more straightforward approach approach and improved on K6 by adding a number new features as well as improving its overall performance, instead of a complete redesign. | Following [[AMD]]'s acquisition of [[NexGen]] in [[1995]] and the success from the release of {{amd|K6}} (a rebranding of NegGen's {{nexgen|Nx686}}), AMD had the financial means of developing the [[microarchitecture]] further.
