CPU

CPU

1. Cores

   • A CPU can contain one or more processing units
   • CPUs with multiple cores have more power to run multiple programs at the same time

2. Clock Speed

   • Indicates how fast the CPU can run
   • Measured in megahertz or gigahertz

3. Cache Size

   • Small amount of memory which is a part of the CPU
   • Cache is graded as Level 1 (L1), Level 2 (L2) and Level 3 (L3)

4. Processor Type

   • Two main types of CPU: CISC and RISC
   • CISC has more instructions, is larger, has a higher clock speed, uses more energy and is more expensive than RISC
