It's funny that your claims never need evidence, but everyone else's you don't believe do.
Why don't you discuss things like an adult.
I've made a point, the gap between cores needs to be big enough to make sense and for Vega to have HBM2 it really needs more shaders to take advantage of that memory bandwidth. Both of these things would lead to a fairly logical conclusion that small vega is bigger than the 1080 and probably by a reasonable amount, it has to be big enough to create a significant gap to RX480, for both itself and salvaged parts to be made from the core. Now be an adult and come up with a reason why small Vega would be only 80mm^2 bigger than RX480 and thus only the same size as the 1080 die. Come up with a reason that attempting to match shader count and die size to HBM2's available bandwidth doesn't make sense. I can think of a few myself.
I reasonably discuss the reasoning behind rumours, I'm not at all always right but I put across an adult discussion that only descends into farce when people like you refuse to discuss rumours in a sensible manor. I think this will happen because X,Y and Z, I don't think that will happen because this that and the other, etc. Not just, it won't happen because I say so and you can't show me the internal design plans for an unreleased product therefore you are definitely wrong.
There ARE leaks that puts small Vega with both HBM2 and 4096 shaders, in fact that 490x rumoured spec has been around for a VERY long time.
But rather than respond reasonably and discuss the merits of my conclusions and either agree or disagree with your own well reasoned counter argument and can almost immediately tell what kind of reply I'll get, why not confound expectations and do something different.
