Microprocessor

Microprocessor type

Intel� Pentium� 4 that runs at 1.80 GHz internally and 400 MHz externally or Intel Celeron� that runs at 1.70 GHz internally and 400 MHz externally

NOTE: Microprocessor offerings vary by country.

L1 cache

8 KB first-level (Pentium 4); 32 KB (16-KB data cache; 16-KB instruction cache) (Celeron).

L2 cache

256- or 512-KB (displayed in the system setup program) pipelined-burst, eight-way set associative, write-back SRAM (Pentium 4);

128-KB SRAM that resides in the processor�s core. The L2 cache runs at the processor�s internal clock speed (Celeron).
