and going strong.
AMD K6 (1997)
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.
Cyrix 6x86MX (1997)
Well,

Intel came up with MMX and AMD was already using it starting with the K6. So, Cyrix had to get in on the game as well. The 6x86MX, also dubbed "M2", was Cyrix's answer. This processor took on the MMX instruction set, as well as took an increased 64KB cache and an increase in speed. The first M2's were 150 MHz chips, or a P-rating of PR166 (Yes, M2's also used the P-rating system). The fastest ones operated at 333 MHz, or PR-466.
M2 was the last processor released by Cyrix as a stand-alone company. In 1999, Via Technologies acquired the Cyrix line from it's parent company, National Semiconductor. At the same time, Via also acquired the Centaur processor division from IDT.

Pentium II (1997)
Intel made some major changes to the processor scene with the release of the Pentium II. They had the PentiumMMX and Pentium Pro's out into the market in a strong way, and they wanted to bring the best of both into one chip. As a result, the Pentium II is kind of like the child of a Pentium MMX mother and the Pentium Pro Father. But like real life, it doesn’t necessarily combine the best of it’s parents. Pentium II is optimized for 32-bit applications. It also contains the MMX instruction set, which is almost a standard by this time. The chip uses the dynamic execution technology of the Pentium Pro, allowing the processor to predict coming instructions, accelerating work flow. It actually analyzes program instruction and re-orders the schedule of instructions into an order that can be run the quickest. Pentium II has 32KB of L1 cache (16KB each for data and instructions) and has a 512KB of L2 cache on package. The L2 cache runs at ½ the speed of the processor, not at full speed. Nonetheless, the fact that the L2 cache is not on the motherboard, but instead in the chip itself, boosts
