CPU, fan, memory ... Actually, the CPU has a little bit of memory. On-board cache, refers to cache memory on the CPU die, and not "on a board" such as the motherboard. Early versions of CPUs frequently had 'support chips' which were required, and worked almost as if they belonged on the CPU die. Progressing further along the learning curve, this functionality migrated to the CPU die. My understanding is that SRAM, which is non volatile, consumes less power, and doesn't require refresh, is becoming more cost effective. SRAM has the power, speed, and price to be appropriate for high-end circuitry. I saw somewhere where people are working on 'refresh-free' DRAM. Cheerios, PW.
