AMD Opteron™ Processor Model Numbers and Features Comparison

See also: Processor Quick Reference Guide
 
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 servers and workstations
200 Series = Up to 2-way servers and workstations
800 Series = Up to 8-way servers and workstations

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.
