I think there has been a big uptake in things you don't see like embedded or FPGA cores but as a general CPU it's nowhere near as efficient as ARM/x86 right now is my understanding. So it might be running in the SSD and the Fan controller but not as the CPU. I think a large part of the cost of a CPU core is not the instruction set but the optimisation of the CPU and ARM/Intel/AMD are still way ahead in those. And so it needs people to optimise the cores, which when they have done that they charge for being a better CPU.
