Not totally true. Intel obviously builds its chips to fit its markets, and while the consumer chips have been improving mostly in power consumption (because of the shift to laptops and the miniaturisation of those laptops) their server chips have been improving in performance also, where there are no such constraints. For example, Intel will happily sell you an 18 core 2.3GHz Haswell Xeon with a design power of 145W, or a 10 core 3.1Ghz processor that puts out 160W.
