History
The K6-2 was designed as a competitor to
Super Socket 7, which increased the processor bus from 66 MHz to 100 MHz, allowed the K6-2 to withstand the effects of ever-increasing CPU multipliers fairly gracefully and in later life it remained surprisingly competitive. Nearly all K6-2s were designed to use 100 MHz Super Socket 7 mainboards, allowing the system-bus to keep pace with the K6-2's clock-frequency.
The K6-2 was a very financially successful chip and enabled AMD to earn the revenue it would need to introduce the forthcoming Athlon. The introductory K6-2 300 was by far the best-selling variant. It rapidly established an excellent reputation in the marketplace and offered a favorable price/performance ratio versus Intel's Celeron 300A. While the K6-2 had mediocre floating-point performance compared to the Celeron, it offered faster system RAM access (courtesy of the Super 7 mainboard), as well as 3DNow graphics extensions.
As the market moved on, AMD released a long series of faster K6-2 parts, the best-selling ones being the 350, 400, 450, and 500. By the time the 450 and the 500 were mainstream parts, the K6-2 family had already moved to the budget PC segment, where it still competed successfully against Intel's Celeron.
K6-2+
Despite the name, the little-known K6-2+ was based on the AMD K6-III+ design (model 13) with 128 KiB of integrated
Most K6-2+ motherboards did not support a clock multiplier setting greater than 5.5 since 550 MHz was the highest official speed of the K6-2+ (100*5.5 = 550) but a little known feature of both the K6-2 and K6-2+ was that it interpreted the motherboard clock multiplier setting 2 as 6. This allowed many users to run their K6-2+ 550 MHz and often even a K6-2+ 500 MHz at a speed of 600 MHz simply by setting the motherboard clock multiplier to 2.[5]
