Of course there is wishful thinking, aren't we all sick of Intel and Nvidia abusing their dominant positions to utterly fleece their customers? I've said many times before that I don't think the pricing in the Navi leaks is realistic, even if it represents AMD's MSRP. Market factors will push it up and if AMD see an opportunity to make cash they, of course, will do so.
But what I'm arguing against is Nvidia and Intel-levels of price gouging. There is no way in hell AMD can expect to flog Navi cards anywhere near Turing prices, it would be a sales suicide. Low margin, high volume is a thing and it is successful in making a profit. Now yes, history has shown that AMD will charge stupid, unwarranted money for their graphics cards but yet we've seen backlash for it, and I would like to think that they won't make the same mistake yet again.
Zen pricing shows that something may have clicked with them and, with the exception of the 1800X (notably not repeated with Zen+), nothing in the Ryzen, Threadripper or EPYC lines since its inception has been bonkers money.
The 2700X is not 9900K money despite being in the same performance ballpark. 2600 and 2600X is not 8700K/9600K money. Threadripper significantly undercuts Skylake X. So why suddenly are people talking about Zen 2 costing Intel equivalent money? Why does Lisa Su's measured and intentional CPU pricing logic not apply to her GPUs?
Give it a couple of years until Intel have been ground into dust and AMD are the dominant CPU player. Give it a couple of years until AMD have closed the gap to Nvidia and are properly competing and beating across all ranges. THEN AMD can (and will) abuse their market dominance with prices. But they can't right now, so they won't.
