I am far from a tech geek , I have a question regarding mining bitcoin. Why is there a strong need for a video component to mining bitcoin? It just strikes me as odd that there is this data network thing which for some reason needs such advanced video capacity. anyone?
GPUs are great at parallel number crunching. Basically, that power is being used for general purpose computations rather than rendering graphics to a screen. This wikipedia article probably explains it better than I can: https://en.wikipedia.org/wiki/General-purpose_computing_on_graphics_processing_units
