 People forget that quite recently GPU design with a focus on low power consumption has been able to match the PS4/Xbox1 level; research the Tegra K1.

I'm sure you're thinking here of Tegra X1 and PS360. Tegra X1 peaks at 512GFLOPS (FP32) with enough TMUs and ROPs to actually beat PS360, but it's nowhere near XBO, let alone PS4.

K1 was advertised as being better than PS360 (on paper it had more GFLOPS), but actually it was not due to low TMU/ROP count and low memory bandwidth.

Of course, problem with all these mobile GPUs is for how long they can sustain their advertised peak performance before throttling down to avoid melting.

Yup great explanation, it's difficult to put a powerful GPU under a portable device especially heating problem.
