System Performance

1. Clock Speed

   • The number of instructions a single processor can carry out per second
   • the higher the cock speed the more instructions can be carried out
   • computers can be overclocked, meaning they can be made faster
     • if not done correctly can cause CPU to overheat, crash or cause permanent damage

2. Number of cores

   • Each core can process data individually
   • more cores means more instructions can be carried out
     • however, doubling the amount of cores does not mean double the processing speed

3. Cache Size

   • memory inside the CPU that stores data for quick access
   • faster than RAM
   • larger cache means faster access to more data
