But it wasn't the point of discussion.
The point is, if we project the current AMD opensource driver state to RAM chips(thanks to von Neumann we don't need a driver for them) , you would have 2GiBs free out of 8GiBs installed. You invest 60 dollars and have 15 dollar effect. Consuming whole as-if "60 dollar" electricity. Producing as-if "60-dollar" heat. Delivering as-if "60 dollar" features. Thanks only to driver. Which AMD writes happily for windows for free.
