Understanding Third-Generation AMD Opteron™ Processor Model Numbers

Understanding Third-Generation AMD Opteron™ Processor Model Numbers

Third-Generation AMD Opteron™ processors are identified by a four digit model number, ZYXX, where:

Z—indicates the maximum scalability of the processor.
1000 Series = 1-way servers and workstations
2000 Series = Up to 2-way servers and workstations
8000 Series = Up to 8-way servers and workstations

Y—indicates socket generation. This digit is always ‘3’ for Third-Generation AMD Opteron processors for Socket F (1207) and Socket AM2.
1000 Series in Socket AM2 = Models 13XX
2000 Series in Socket F (1207) = Model 23XX
8000 Series in Socket F (1207) = Model 83XX

XX—indicates relative performance within the series.
An AMD Opteron Processor Model 2350 is higher performing than an AMD Opteron™ Processor Model 2347, etc.
XX values above 40 indicate a Third-Generation Quad-Core AMD Opteron processor
XX values 40 and below indicate a Third-Generation Dual-Core AMD Opteron processor (available in 1H’08)

HE—indicates a 68W low-power AMD Opteron™ processor.
Performance of a low-power AMD Opteron processor HE model number, ZYXX, is equal to the performance of the same model number standard-power version. For example, an AMD Opteron processor Model 2347 HE offers the same performance as a standard wattage AMD Opteron processor Model 2347.
