CPU vs. GPU
A general-purpose processor versus a parallel processor optimised for graphics/maths.
The comparisoni
“The CPU runs the operating system — sequential general-purpose tasks. The GPU is a parallel processor designed originally for graphics, now also used for ML.”
The ruleii
¶
CPU = general. GPU = parallel.
CPU: Central Processing Unit — small number of fast, general-purpose cores; runs the OS, applications, sequential code. GPU: Graphics Processing Unit — thousands of slower cores running in parallel; great for graphics and matrix maths (hence ML).
Memory aidiii
Remember it like this
CPU = brain. GPU = many hands.
