I think all the mobile GPUs use UMA. I think the tradeoff point is some complicated function of power envelopes and the benefit of more, though slower, memory vs raw performance at any power or $ cost. Though there are several dozen important algorithms that run much better on GPUs, there are really only two of them, 3D graphics and ML tensors, that have had a big consumer and broad professional appeal.
