No, that's not the reason space computers are behind. Space computers are behind because space technology is based on minimizing risk given the large cost of failure. Using older nodes with well-understood flaws that can be built using old chip equipment is much lower risk than trying to put Intel's latest into a communications satellite. Few things in space truly would require anything state of the art. The best argument I can think of would be realtime image processing using DNNs- imagine you made a fleet of 1M identical exploration bots and you wanted them to filter out most of their imaging data before sending back the best candidates.
