I find it really hard to get excited about AMD being king of cheap mid range gpu's. I would think that is the worst segment to be in, and is rapidly being eaten away by mobile, consoles etc.
If AMD's market research is correct; not true. And sub $100 is "cheap". AMD is aiming at the bulk of the bell curve.
about slide 11 here

Why does it take 10 slides to get to the major "punch line" ? ... I have no idea. ( that must of been animated "whiz through" slides. ). That other 16% is the far more profitable part, but AMD needs to get to breakeven before start worrying about some "print money" scheme.
In short, what AMD is trying to aim at is bring the "old" high end down to the point where people can actually afford ... as opposed to just lust after. The "old" bottom end is disappearing so bring the old top down and spread it out more broadly. Not chase the bottom end.
(although in terms of consoles ... AMD has the pretty much covered too. That area isn't a problem a problem now and shouldn't be next couple of years either. )
How many people actually know enough to sink money into desktop graphics, but are also willing to settle for mid range performance? Especially with VR and high resolution displays on the horizon.
There is a bigger block of people not going anywhere, but it is far easier to start out with the folks who are moving/buying.
With the huge installed base of PCs that can't drive a VR or utra high res display ..... they need new cards. AMD is looking to make them more in reach. Even folks moving from 1080p to 4K ( or very high FreeSync frame rates). There is a slide that points out that 95+ % of gamers are still down on 1080p ( for all the yelping about " 4K is old news it is 5K or bust" in these forums. )
The fanboy lead flame wars online would lead you not to believe it is because over represented with folks who do spend sizable amounts of money, but if is look at larger user population get something closer to:
The GPU more affordable doesn't completely cure this for VR. However, they could get more folks off of being stuck at 1080p . Move card now... buy VR later when the hype tax isn't as high (and/or have more money).
Talking about this stuff isn't AMD's problem. It is shipping and execution. VR isn't going to save AMD short and medium term. Most potential buyers don't have the budget to move even if want to. IMHO, whether the 470 and 460 ( not aimed at VR) do well or not is going to mean difference in turning around.
