Well, the EM environment would be a CPU die on a motherboard full of gigahertz chips, it means this EM environment has been so much "improved" they can double the speed?? I am really curious at how they choose to limit the speed of USB lanes, that said I really don't like that as this smells "don't go too fast or we won't be able to sell USB controllers with really faster lanes". I would understand if one of the major limiting elements is the controller silicium process (2nm/5nm/etc).
