A400M vs An-70

Today came news that russians decided to pick up An-70 project which is reported to require 300 mln $.

Now A400M equiped with less advanced turboprop engines and lesser take off weight have 7000km range with 20t, while An-70 reported to make 6600km with 20t. Why is that? Ain’t Antonov’s state of the art propfans supposed to be more fuel efficient?
