The K6 gave AMD a real leg up in performance, and it virtually closed the gap between Intel and AMD in terms of Intel being perceived as the real performance processor. The K6 processor compared, performance-wise, to the new Intel Pentium II's, but the K6 was still Socket 7 meaning it was still a Pentium alternative. The K6 took on the MMX instruction set developed by Intel, allowing it to go head to head with Pentium MMX. Based on the RISC86 microarchitecture, the K6 contained seven parallel execution engines and two-level branch prediction. It contained 64KB of L1 cache (32KB for data and 32KB for instructions). It made use of SMM power management, leading to mobile version of this chip hitting the market. During its life span, it was released in 166MHz to 300 MHz versions. It gave the early Pentium II's a run for their money, but AMD had to improve on it in order to keep up with Intel for long.
