I disagree that unified memory is a bad thing. The usual reasoning that people give for it being bad is: you share memory bandwidth between CPU and GPU, and many things are starved for memory access. Apple’s approach is to stack the memory dies on top of the processor dies and connect them with a stupid-wide bus so that everything has enough bandwidth.
