Microprocessor

Microprocessor type dual Intel® Pentium® III microprocessors with a front-side bus external speed of 133 megahertz (MHz). See System Setup to identify your system's processor speed. A slower compatibility speed can be set through the System Setup program.
Internal cache 32-kilobyte (KB) first-level (16-KB data cache; 16-KB instruction cache)
Level 2 (L2) cache memory see System Setup to determine the amount of L2 cache your system supports.
Math coprocessor internal to microprocessor
