To achieve maximum processing performance each system component must be compatible and work together. This means that chip performance, cache, memory, the operating system and the graphics adapter contribute to overall performance. For example the chip must work hand in hand with the chipset. Both are rapidly advancing in processing speed and power. CISC chips are developed from silicon and the fastest have aluminum interconnects.
Chips typically contain internal and external cache.
L3 is commonly associated with RISC chips. For the larger L1 or L2 caches, the cache is internal or external and runs at the CPU's full speed or something less. The larger the set, the greater performance on cache hits. Also, socket sets should be compatible with the chipset to enhance system performance. Typically, RISC chips are less costly to design, test and manufacture because of the reduced instructions.
