These aren't facts though, all the conclusions you've came to are based on conjecture, your comparisons are purely on marketing names, and marketing departments are often the least technically wise part of a tech company you can get, if you look at it on a mm^2 basis, Turing is the same price as Pascal, there's a fact for you. PS. At no point have I ever implied NVidia's pricing is in any way reasonable (Technically justifiable and logical != reasonable, for reference I havn't owned an NVidia card since I got given a 780).
Another one: NVidia spent more R&D money on Turing than any GPU manufacturer has ever spent on any GPU architecture, ever.
Or maybe: Turing dies are larger than their Fermi equivalents were [GF100= 529, GF104 = 331, GF106 = 240 whereas TU102 = 754, TU104=545, TU106 = 445]
NVidia's pricing has been fairly consistent in terms of GPU code names(Not marketing names) or die size, maybe marketing material or positioning would be different if AMD were competetive, but pricing won't budge as long as NVidia maintain mindshare, attempting to lay the onus for NVidia's pricing on AMD is neither useful nor does it fit into the timescales tech companies work on or how competition actually works in a duopoly. Look at Intel.
What has Intel done since AMD was competitive? Raised prices, across the board, at every marketing tier. Kept per mm^2 pricing exactly the same.
I'm not trying to argue for value or anything like that, my arguments re: Turing has always been that it's badly placed for the consumer market, in fact borderline completely irrelevant due to its price, but the pricing does have technological precedent. As I've said before, if AMD were competitive I don't think Turing would have ever reached consumers given how the smallest Turing die is the same size as Pascal's Titan's die, I honestly think we'd just have nothing instead, and I have no comment regarding a preference of the two personally but I think having DXR hardware in consumer hands is a very useful thing for software developers.
