According to the link Mark posted, they are down to 3 nm on some Apple M3 and M4 chips. At that size, how much current can even flow through that thing??? There are several others at 4 nm and 5nm. Quite a few actually. It seems they found a way to break quantum law. o_O They seem to have done that about 3 years ago. Somebody has a serious slide rule. O_O Dale :-) :-)
