content: My only issue with your descriptions is the use of the term speed, 5Mbs and 1Gbs are the same speed they are different bandwidths meaning throughput. both of those will be near identical on a low quality video, both will send small things at the same pace. The difference is in bulk it is like comparing a Jetta with a Semi, neither is the any faster on a 55mph road but one can move a lot more stuff at one time. 4K doesn't need faster, dial up has response times perfectly acceptable for 4K video what it is missing is bandwidth to send a large file. It gets perceived as speed just like the semi gets seen as speed for delivering 200 TVs, the speed is the same the load is larger per trip though.
