Note: ‘E’, ‘B’ and ‘EB’ nomenclature is used to differentiate processors within a processor speed designation when there is an overlap between processor frequencies and functionality.
- ‘E’ designates Advanced Transfer Cache and Advanced System Buffering support.
- ‘B’ designates 133 MHz System Bus support.
- ‘EB’ designates Advanced Transfer Cache, Advanced System Buffering and 133 MHz System Bus support.

Note: All processors greater than 600 MHz include the Advanced Transfer Cache and the Advanced System Buffering functionality.
