Global InformationList of AMD Opteron processors information
Opteron is the name of a central processing unit (CPU) family within the AMD64 line. Designed by Advanced Micro Devices (AMD) for the server market, Opteron competed with Intel's Xeon. The Opteron family is succeeded by the Zen-based Epyc, and Ryzen Threadripper and Threadripper Pro series.
For Socket 940 and Socket 939 Opterons, each chip has a three-digit model number, in the form Opteron XYY. For Socket F and Socket AM2 Opterons, each chip has a four-digit model number, in the form Opteron XZYY. For all Opterons, the first digit (the X) specifies the number of CPUs on the target machine:
- 1 – has 1 processor (uniprocessor)
- 2 – has 2 processors (dual processor)
- 8 – has 4 or 8 processors
For Socket F and Socket AM2 Opterons, the second digit (the Z) represents the processor generation. Presently, only 2 (dual-core), DDR2, 3 (quad-core) and 4 (six-core) are used.
For all Opterons, the last two digits in the model number (the YY) indicate the clock rate (frequency) of a CPU, a higher number indicating a higher clock rate. This speed indication is comparable to processors of the same generation if they have the same amount of cores. Single-cores and dual-cores have different indications, despite sometimes having the same clock rate.
Model number methodology for the AMD Opteron 4000 and 6000 Series processors.
AMD Opteron processors are identified by a four digit model number, ZYXX, where:
Z – denotes product series
- 4000 Series = Low cost and power optimized 1- and 2-way servers
- 6000 Series = High performance 2- and 4-way servers
Y – denotes series generation
- 41xx = 1st generation of 4000 series
- 61xx = 1st generation of 6000 series
XX – communicates a change in product specifications within the series, and is not a relative measure of performance.
The suffix HE or EE denotes a high-efficiency or energy-efficiency model with a lower thermal design power (TDP) than a standard Opteron. The suffix SE denotes a top-of-the-line model with a higher TDP than a standard Opteron.
