AMD Processors OPN and Identification
AMD Processor Ordering Part Number (OPN) Breakdown
Processors are identified by markings known as Ordering Part Number (OPN).
The OPN identifies the processor and its specifications.
Processor Core Architecture/Brand Name:
These alpha characters define the core architecture of the processor.
Model Number:
This four digit numeric field defines the speed of the processor in megahertz or Model Number as appropriate.
Package Type:
This single alpha character defines the package type for this device.
Operating Voltage (Nominal Core Voltage):
This single alpha character defines the voltage for this processor.
Maximum Die Temperature:
This single alpha character defines the maximum die temperature for this processor.
Level 2 Cache Size:
This single alpha character defines the Level 2 Cache Size for this processor, in addition to 128KB Level 1 Cache.
Maximum System-Bus Speed:
This single alpha character defines the maximum System-Bus speed for this processor.
Stepping and date of birth:
Examples:

CPU跟GPU合體不算是新聞，Clarkdale處理器就包了這2個晶片，不過AMD與Intel這次玩更大，要把CPU跟GPU整合成單晶片，AMD 推出Fusion架構APU（Accelerate Processing Unit），而Intel則拿出Sandy Bridge應戰。
