Chips vary considerably in the amount of power they use at a given frequency, as a result of silicon process variations. Consider table 5 in http://charm.cs.illinois.edu/newPapers/16-08/paper.pdf. So even with identical cooling systems, some chips will outperform others.
This is purely a mechanical engineering issue. They haven't designed it properly.
