AMD Thuban core

AMD Thuban core was launched in April 2010 in Phenom II X6 1055T and 1090T microprocessors. The core is built on K10 microarchitecture, and it packs 6 CPU cores on a single die. Since its introduction Thuban core was used in all other members of Phenom II X6 family. It was also utilized as a base of Zosma core, that has two out six CPU cores locked.

New core features:

• Six CPU cores on a single die.
• Turbo Core technology. This feature can boost frequency of active CPU cores, when three or more cores are idle.

Thuban-based Phenom II microprocessors can be identified by:

• Part number: OEM part numbers start with "HD" and end with "6DGR". Box part numbers start with "HD" and end with "GRBOX".
  Examples: HDT55TWFK6DGR, HDT90ZFBGRBOX
• CPU ID: CPU identification number of Thuban processors is 100FA0. Please note that the same CPUID is returned by CPUs with Zosma core.
