Ok, I understand that. But can someone explain why mining requires only uses a few kB/s?
I would imagine it's because after being given the task, it doesn't need to talk to the rest of the computer much as long as it's calculating. Drawing graphics and such must require much more communication with the rest of the PC, sending and receiving tons of new information every second.
So far so good, but when the gpu decides to communicate, what does it communicates and why?
Thanks for the answers, guys.
