| MMX | Instruction set extension for certain Pentium CPUs as well as the K6-2/III series which can be used for multimedia applications, but rarely applied. |
| 3DNow! | Instruction set extension for K6-2/III series which can be used for 3D applications, often applied. |

| Architecture/Cache | |
| onboard | The L2 cache for Socket 7 CPUs is placed on the motherboard. It can vary between 512 and 2048 kByte depending on the motherboard product itself. |
| L3 | The AMD K6-III has got 256 kByte on-die (internal) L2 cache. The external cache on Socket 7 boards becomes then so-called L3 cache. |
| Cache | Motherboard cache (L2 or L3) runs in-sync with the system bus. Therefore it is not dependent on the CPU clock such as on the Pentium III or AthlonThe K6-III cache frequency of 100 MHz refers to the L3 cache. The L2 on a K6-III is on die and runs at full speed. |
