What determines bytes per second a computer can process?

[Tabaristiio]

What are the factors which determines how many bytes / kilobytes / gigabytes of data a computer can process every second? Are there any equations / formula / rules that can be used to work this out.

Big factors are cpu speed, cpu word size, memory speed, bus speed and size, threading capabilities, ALU speed. There are others, depending somewhat on what KIND of processing you are talking about. It's a big subject.

I'm referring to image processing, such as a robot having image processed by its control unit when 'seeing' things through its eyes / visual system (such as through cameras).

Then my answer stands but now I have to add "amount of I/O processing required"
