The Coppermine core was instroduced on Oct 25, 1999. The core is based on P6 microarchitecture.

New features in the core:

• 0.18 micron manufacturing process
• 256 KB on-die level 2 cache
• Lower core voltage
• Lower power consumption
• Flip-Chip Pin Grid Array package

Microprocessors with Coppermine core can be identified by:

• Part number: part number contains "80526", but not "80526K". For example: RB80526PY600256.
• CPU ID: 681, 683, 686 and 68A. Please note that Pentium III Xeon CPUs have CPU IDs 68x, and Coppermine-T processors have CPU ID 68A.

Celeron microprocessors have modified Coppermine core that includes 128 KB of level 2 cache memory. To distinguish it from Pentium III Coppermine core with 256 KB L2 cache the Celeron core is often called Coppermine-128.
