Models
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 first, second, and third-generation Opterons, the first digit (the X) specifies the number of CPUs on the target machine:
- 1 - Designed for uniprocessor systems
- 2 - Designed for dual-processor systems
- 8 - Designed for systems with 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, DDR2) and 4 (six-core, DDR2) are used.
Socket C32 and G34 Opterons use a new four-digit numbering scheme. The first digit refers to the number of CPUs in the target machine:
- 4 - Designed for uniprocessor and dual-processor systems.
- 6 - Designed for dual-processor and four-processor systems.
Like the previous second and third generation Opterons, the second number refers to the processor generation. "1" refers to AMD K10-based units (Magny-Cours and Lisbon) and "2" refers to the Bulldozer-based Interlagos and Valencia-based units.
For all Opterons, the last two digits in the model number (the YY) indicate the clock frequency of a CPU, a higher number indicating a higher clock frequency. 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 frequency.
The suffix HE or EE indicates a high-efficiency/energy-efficiency model having a lower TDP than a standard Opteron. The suffix SE indicates a top-of-the-line model having a higher TDP than a standard Opteron.
Starting from 65 nm fabrication process, the Opteron codenames have been based on Formula 1 hosting cities; AMD has a long term sponsorship with F1's most successful team, Ferrari.

Famous quotes containing the word models:
“The parents who wish to lead a quiet life I would say: Tell your children that they are very naughty—much naughtier than most children; point to the young people of some acquaintances as models of perfection, and impress your own children with a deep sense of their own inferiority. You carry so many more guns than they do that they cannot fight you. This is called moral influence and it will enable you to bounce them as much as you please.”
—Samuel Butler (1835–1902)
“Friends broaden our horizons. They serve as new models with whom we can identify. They allow us to be ourselves—and accept us that way. They enhance our self-esteem because they think we’re okay, because we matter to them. And because they matter to us—for various reasons, at various levels of intensity—they enrich the quality of our emotional life.”
—Judith Viorst (20th century)
“The greatest and truest models for all orators ... is Demosthenes. One who has not studied deeply and constantly all the great speeches of the great Athenian, is not prepared to speak in public. Only as the constant companion of Demosthenes, Burke, Fox, Canning and Webster, can we hope to become orators.”
—Woodrow Wilson (1856–1924)
