AMD Athlon Thoroughbred core

Identification of microprocessors with Thoroughbred core:

  • By part number: part numbers start with one of the prefixes: "AMSN", "AXDA", "AXLD", "AXM" or "SDA" and end with "3B", "3C" or "3D".
    An example: AXMS1400GWS3B
  • By CPU ID: First two digits of CPU identification number are "68".
To improve processor scalability AMD redesigned the Thoroughbred core. To distinguish between the original and redesigned core the cores are often called Thoroughbred A and Thoroughbred B. The differences between these two revisions of the core are:
Thoroughbred AThoroughbred B
