I'm going to guess the Vega 64 is what the PS5 is going to be rocking. Of course, I'm going to guess it'll be somewhat customized with a few advancements in tech made along the way. So, ~6.5X-7X more powerful than the OG PS4 and 3X more powerful than the Pro. Add in a much better Zen or Zen+ CPU and 16GB of RAM. I'd say that's good enough for a generation leap.
