The kinds of problems these machines might be able to solve are of a completely different type than current computers, so the way their "speed" is measured will be different. For example, a biological system might be able to perform calculations in a few seconds which we simply don't have the techniques or methods to solve with modern computers in any reasonable amount of time.
