Wondering the same; from my 10,000 ft view a cpu-fpga marriage seems like the kind of thing that could transform how performant general purpose computing is done.
What we have is still a CPU and a GPU. Separate. Discrete. The inclusion changed nothing about what kind of software we can write or problems we can solve. Back when APUs were still just a slide in a powerpoint deck, there was a lot of talk about how this could "change everything" because of the radically different type of compute you could do on a GPU.
The closest thing to this is the coin mining craze, but everyone is gravitating towards the fastest hardware for that. And that's not your APU.
