Efficiency cores are less power hungry.

Intel processors run only e cores unless something requires the power of p cores, thus consuming less power than a regular system would (in theory, at least).
This is akin to how processors had a fixed clock speed earlier, but now almost all of them have a core clock speed and a boost clock speed. The cores are boosted only when higher performance is needed. Intel has made this separation at a core level as well.
E cores are single threaded whereas p cores rum 2 threads each. So an 8p+16e is capable of running 32 threads. And somehow Intel is able to stuff more e cores in a processor. They're putting an insane number of cores on some of their processors.
Look at this comparison, see how they've almost doubled the multi-core performance of an i5 in only 2 generations at the same TDP
