Succession

K6-III was the microarchitecture for AMD's K6-III line of microprocessors as a successor to the K6-2. This short-lived microarchitecture served as a stopgap until K7 was released. K6-III was superseded by K7 in 1999.

Technology[edit]

Like it's predecessor, K6-2, K6-III microarchitecture-based chips were manufactured on AMD's 0.25 μm process, a five-layer-metal process technology using local interconnect and shallow trench isolation, at AMD's Fab 25 wafer fabrication facility in Austin, Texas. K6-III is designed using 21.3 million transistors, with the die packaged using C4 flip-chip interconnection technology in a 321-pin ceramic pin grid array (CPGA) package.
