IBM All-in-One FC/Socket 370 Celeron manual Cache memory, PCM-6890B User Manual

Cache memory

Since the second level cache has been embedded into the Celeron / Pentium III CPUs, you do not have to take care of either SRAM chips or SRAM modules. The built-in second level cache in the Celeron yields much higher performance than the external cache memories. The cache size in the Celeron CPUs is 128 KB, but 256KB for Pentium III CPUs.
