Reply to comment by BobbyThrowaway6969 in ELI5: Why do computers need GPUs (integrated or external)? What information is the CPU sending to the GPU that it can't just send to a display? by WeirdGamerAidan
Agreed, which is why it's wrong to say that GPUs are better at floating point operations than CPU.

Depends how you look at it. Their circuitry can handle vector math more efficiently

No, most GPUs haven't had vector instructions for maybe a decade. Modern GPUs use SIMD waves for parallelization with scalar instructions.
