1.12 Cache Memory
Since the second-level (L2) cache has been embedded into the Intel®
socket 478 Pentium® 4/Celeron™ processor, you do not have to take
care of either SRAM chips or SRAM modules. The built-in second-level
cache in the processor yields much higher performance than the external
cache memories. The cache size in the Intel ® Pentium ® 4 processor is
256/512 KB. In the Celeron CPU, the cache size is 128KB.
