I'm not thinking it, I'm seeing it. It's right there. You can see it too.
And yeah about AMD's engineers and their financial ability to produce competitive consumer chips, actually. Considering how massively Maxwell/Pascal thrash every derivative of GCN in efficiency (transistor count, power, die space) and considering that Vega seems to be dedicating lots of die space to professional market features as a GP100 competitor rather than being focused on consumer/FP32 workloads like GP102, Vega's weak gaming performance for its size isn't an inexplicable shock.
Wait and see for what? Drawing final conclusions on a design? Surely a person can't do that before we get 3rd party testing. But it seems rather foolish at this point to actually expect Vega to be GP102 levels of strong or for it to be some unprecedented leap to Pascal-equivalent efficiency. Nothing indicates that and plenty of information that AMD themselves chose to share indicates something much worse.
While we're waiting to see, we all know the 1080 Ti just cratered Vega's chances and is also sucking up all the Ryzen launch buyers who also want a fancy new GPU to go with it. AMD have yet to even properly counter the 1080 and easily arguably haven't even countered the aftermarket 980 Ti/1070 yet either. AMD's answer? We're getting rumblings of a Polaris rebrand and absolute silence on a final release date for Vega, a GPU that AMD can't even show significantly outperforming GP104 in Doom of all things.
Hope is one thing, outright denial is another.
