AMD Opteron Processors are identified by a three digit model number, XYY, where:

X—indicates the maximum scalability of the processor. In other words:
100 Series = 1-way server and workstation (UP server and workstation)
200 Series = up to 2-way server and workstation (2P server and workstation)
800 Series = up to 8-way server and workstation (MP server and workstation)

YY—indicates relative performance within the series. In other words, an AMD Opteron Processor Model 244 is higher performing than an AMD Opteron Processor Model 242, etc.

Low-power AMD Opteron Processors are identified by a two character modifier, where:

HE—indicates a 55W processor within the series.

EE—indicates a 30W processor within the series.

The chart below further explains the differences between AMD Opteron Processor series and model numbers.
