Radeon Pro specs hint at a full-fat Polaris 11 GPU in MacBook Pros

Apple's latest MacBook Pros house a new line of Radeon Pro graphics processors: the Radeon Pro 450, the Radeon Pro 455, and the Radeon Pro 460. AMD has given us some more info on those graphics processors in the wake of Apple's unveiling. While the red team didn't say as much, the fact that it's touting the thinness of these chips and the GPUs' spec sheets point to a Polaris 11 chip underpinning these products. First, though, let's take a look at the specs of these new chips (along with a couple educated guesses about their performance). I've marked my guesses with question marks.
