Computing Performance

Computing Performance

1. Clock Speed

   • What
     • Clock speed is the amount of cycles the CPU can process per second
     • Clock speed is measured in gigahertz (GHz)
   • How
     • The higher the clock speed, the more instructions the CPU can process per second, which can improve your computer's performance

2. Cores

   • What
     • Cores are small, independent processors that are embedded inside the CPU.
     • They all work simultaneously.
   • How
     • The more cores there are, the more instructions that are processed, which make the computer's performance better

3. Cache

   • What
     • Cache is a small amount of memory that stores the regularly accessed instructions
     • It is either inside of the CPU or the RAM
   • How
     • If there is a large amount of cache, there are more instructions that can be frequently accessed, which will improve the computer's performance

4. RAM

   • What
     • RAM is volatile (memory is lost if power supply is disconnected)
     • RAM stores instructions and data while a program is running
   • How
     • The greater the RAM, the more instructions that can be stored there so less is stored in the virtual memory, which is slower,improving the computer's performance
