The Willamette core was introduced on Nov 20, 2000. This core is based on NetBurst microarchitecture.
Identification of microprocessors with Willamette core:
- By part number: The part number contains 80528 (but not 80528K),
For example: RN80528PC033G0K
- By CPU ID: First two digits of CPU identification number are F0 or F1.
Please note that Xeon processors with Foster core had that same CPUIDs
as Willamette processors.
Celeron microprocessors have modified Willamette core that includes
only 128 KB of level 2 cache memory. To distinguish it from Pentium 4
Willamette core with 256 KB L2 cache the Celeron core is often called
