  • RISC stands for reduced instruction set computers
  • CISC stands for Complex Instruction Set Computers
  • In CISC there is a large instruction set. The goal is to try and execute in as few as lines as possible in assembly code, these instructions are built into the hardware.
  • In RISC the compiler has to do more work to translate high level code to machine code compared to CISC.
  • In RISC more RAM is required to store the code compared to CISC.
  • Multi-core CPUs have multiple independent cores that can complete instructions separately which results in higher performance
