comparison celeron

I'd like to ask something about a comparison betweenIntel®

Celeron® Processor N2940 (2M Cache, up to 2.25 GHz)

and

Intel® Celeron® Processor 3205U (2M Cache, 1.50 GHz)

The first one: 2.25 GHz, lithography 22nm, 4 cores.......TDP 7.5W

The second one: 1.50 GHz, lithography 14nm, 2 cores.....TDP 15W

So the faster one, with 4 cores and made at 22 nm has got half the tdp of the slower one with 2 cores and made at 14 nm? How is it possible?
