CISC v.s. RISC

RISC is a philosophy to use simpler instructions to achieve the same as complex instruction. For example for AES rowshifting an Intel can use XMM instructions to shift multiple rows in one operation, while RISC processors need to loop through the bytes and execute simpler instructions. It takes longer to execute, but without SIMD the processor is smaller, cheaper and wins in power efficiency.
