The first core of the next Intel microarchitecture, NetBurst, was Willamette.

The Tualatin core was introduced in 2001. The core is based on P6 microarchitecture.

New core features:

• 0.13 micron manufacturing process
• 512 KB on-die level 2 cache
• Lower core voltage
• Lower power consumption
• AGTL system bus

Microprocessors with Tualatin core can be identified by:

• Part number: part number contains "80530".
  For example: RJ80530GZ014512.
• CPU ID: First two digits of CPU ID are "6B". All production versions of Tualatin processors had CPU ID 6B1 or 6B4.

To distinguish between Tualatin Pentium III cores that have different sizes of L2 cache, the core with 256 KB L2 cache is often called Tualatin-256.
