thanks for reply,Road analogy: Bandwidth=speed limit. Bus width=number of lanes.
LOL. You know what the real definitions are, but I didn't want to bring Mhz into the whole bandwidth definition because even though it's right, it's one more thing to try to explain.Bus width is more like the volume of traffic able to be driven. A 192 would be like a 2 lane highway, you can fit 2 cars side by side, followed by 2 more etc, all doing the bus clock speed. A 256 would be like a 3 lane, a 764 like a 6 lane super highway with 6 cars side by side.
Bandwidth is the size of the car, some can carry only 2 ppl (old hdd), a bus can carry 30 ppl (Gen4 NVMe)
Bus clock is the speed the car can move, according to travel conditions.
If I got the analogies straight lol.
