On this page you will find a list of all known (to me) K6 Family CPU speeds with their corresponding multipliers and front-side bus settings. The “+”, “Mobile” and “Embedded” versions are also listed. The last column lists the introduction year, L1/L2 cache size and typical/maximal power consumption when I could find them in the official AMD data sheets or other websites.
If you see an error or know of any other chip which existed, please tell me!
Because they are slowly disappearing from AMD’s website I also include a bunch of technical documentation in PDF format. Some documents right here are general and common to all CPUs and the specific data sheet for each CPU is provided in each section.

I own a K6-2+ 500 ACZM. I have never known what the difference is with the ACZ.
The AMD_K6-2+_Mobile_Datasheet.pdf doesn’t mention ACZM either.
An “engineering sample” is what I once heard suggested. Possibly, but if anyone knows please tell.
