Processors have three types of caches used for storing memory:

L1: Integrated into the processor directly.

L2: Is not integrated into the processor but is still within the processor’s housing. Also known as on-die cache.

L3: This cache is usually only used by some of the most powerful processors and is located either in the housing of the CPU or on the motherboard.

The difference between a CPU and a GPU is that a GPU is more specialized at running video and graphics related processes and data while CPUs are generally more adept at doing a variety of tasks.

Three ways a processor can be cooled is:

Fan: Pushes or pulls air throughout the computer causing the hot air to leave and for cooler air to enter

Liquid Cooling: Liquid is run throughout the computer system. The liquid absorbs heat before being circulated outside the computer where it cools and releases the heat before going back into the computer.

Heat Sink: A piece of metal is placed on top of the processor to absorb the heat it produces for the cube is cooled by a fan. Aluminum and copper are metals that are commonly used.
