Let's not get confused between old and "derived from" because almost every AESA radar in service has been "derived from" older radars - basically because not much point in reinventing the wheel each time. AFAIK the only F-16 radar that was built entirely from the ground up was the original APG-66 (WX-200) because there was no other suitable digital solid state radar around.
Also correct me if I am wrong but the ES-05 Raven was originally the PS-05 AESA which put an active array onto the existing PS-05A back end.
According to NG the 83 can use the same power and cooling as the 68 but you would have to ignore the trend to reduce power requirements in solid state components over the past 15 years (an eternity) to really conclude this is a significant limitation. Greece and Morocco are happily replacing APG-68v9s (a radar claimed to have 33% better range than the 68v5) so it probably ain't that bad!
