There's a slightly lower clock speed, but its really going to be up to the OEMs to make this all work from a cooling perspective. I suspect your average gaming laptop is so big and heavy that having another big fan in there is not going to really bother anyone. Its probably going to be a kludgier solution, but the M series GPUs are fairly terrible, often a fraction of the performance of their desktop equivalants. I think Nvidia saw the external GPU thing on the horizon and decided this is the better approach. I tend to agree. I'd rather have a little extra weight and girth in a laptop than worry about a whole external enclosure and not having it when I'm out, or dealing with all the wires and such. From a battery perspective, who cares. Even the M series had to be plugged into the wall for any non-trivial GPU work.
