The Cascades core was introduced on Oct 25, 1999. This core is based on P6 microarchitecture.

New core features:

• 0.18 micron
• On-die L2 cache
• 133 MHz Front Side Bus

Pentium III processors with Cascades core can be identified by:

• Part number: part number contains "80526K".
  An example: 80526KZ933256 2.8V.
• CPU ID: Cascades processors have CPU identification numbers 681, 683, 686, as well as CPU IDs that begin with 6A. Please note that Pentium III Coppermine microprocessors also have 681, 683 and 686 CPU IDs.
