I am not sure, but perhaps in these programs the bus (FSB) may limit the speed more than the cpu. Also, mobile CPUs tend to have reduced or missing features compared to desktop cpus. (i5 is desktop; Atom and I think all ARM are mobile.) Perhaps Plan 9 doesn't use these features so much. Floating point seems to be a big target for slowing down to save power. Perhaps abaco and mothra themselves don't use floating-point calculations for their display. (Check the source?)
