Performance

1. Clock speed

   • What
     • The speed of the fetch, execute and decode cycle
     • Measured in Hertz
   • How
     • The faster the clock speed, the faster it takes for the CPU to reach RAM

2. RAM

   • What
     • RAM is where all the instructions are stored
   • How
     • The greater the RAM, the more instructions and data can be stored while a program is running. This means the less instructions will be stored in the much slower virtual memory and will therefor improve the performance of the computer

3. Core

   • How
     • A single thing running simultaniously

4. Cache

   • What
     • Cache memory is a small amount of memory which is either inside the CPU or closer to the CPU then RAM
     • Cache memory is faster then RAM and more expensive
     • Cache memory stores frequently used instructions
   • How
     • If there is a large amount of cache memory storage, a greater number of frequently used instructions can be stored. This means that more instructions can be shared quickly, which will improve the performance of the computer.
