The Smithfield core was introduced on Apr 18, 2005. This core is based on NetBurst microarchitecture.

New core features:

• Two CPU cores on one die

Pentium D processors with Smithfield core can be identified by:

• Part number: part number contains "80551P".
  For example: HH80551PG0802MN.
• CPU ID: All versions of Smithfield processors have CPU ID F44 or F47.

Pentium Extreme Edition CPUs have modified Smithfield core that includes Hyper-Threading technology. That core is usually called Smithfield XE.
