ARM phones tend to have specialized cores. You have big.LITTLE, added DSP, ML chips, modem DSP and cpu, hardware media decoders and encoders. And of course GPU w/ GPGPU capability. Maybe tensor cores next.

Why would you need a lot of actual CPU power after all that?

Of course it is easier to program for a homogenous architecture, be it CPU or GPGPU.
