The Presler core was introduced on Dec 27, 2005. This core is based on NetBurst microarchitecture.

New core features:

• 0.065 micron technology
• 4 MB L2 cache
• 1066 MHz FSB
• Virtualization technology

Processors with Presler and Presler XE cores can be identified by:

• Part number: part number contains "80553".
  For example: HH80553PG0724M.
• CPU ID: Presler processors have CPU IDs F62, F64 and F65.

Pentium Extreme Edition CPUs have modified Presler core that supports 1066 MHz FSB and incorporates Hyper-Threading technology. That core is usually called Presler XE.
