Nah back in the day they called those gamers 'nerds', now its the norm so certain groups of 'gamers' prefer to label themselves as 'enthusiasts' so they can set themselves apart again
What
@bug says is true. You need to make a distinction from what AMD says it wants to do and what the products have become in reality. GCN was and still is far from efficient for gaming, and Tahiti > Hawaii was having the architecture inch towards a cap in terms of board TDP, heat and stability. This is why GCN still doesn't clock as high as Pascal does and Polaris was a good step forward, but it was simply not enough. That is why it was pushed as a midrange architecture, going bigger with it would have made it run into the same constraints as Hawaii did.
That is why Fury and Vega saw the light and why they needed HBM / more efficient memory. We know today that HBM does not extract greater performance for gaming and AMD missed the boat entirely with GDDR5X. Their timing was bad and it was bad because they were out of options on further expanding GCN. If AMD should have stepped back from the high end it was during the Fury release. That way they would have been able to make bank versus Pascal and they would have only missed the answer to the 980ti. Now, they miss out on almost two generations instead of one and not just on the 1080ti but also the 1080 which is a large chunk of the marketplace with very good margins. They lost to Maxwell because it provided the efficiency already, and Pascal was another leap forward that even Vega isn't the right answer for, even after its countless delays and adjusted promises. Polaris brought Maxwell efficiency a year too late, and it sold because it had nice allround performance at a decent price, not because it was a superb step forward. You don't 'win' battles in the midrange, you just move lots of units. AMD could have also just re-used Hawaii for that segment; they were already rebranding and kicking down GPUs a full tier anyway to keep the product stack filled up.
So yes, today's reality is that we see most of the Vega GPUs land in Frontier and MI25, but its really not because AMD wanted to all along, its because they are forced to do so to at least make SOME money out of it.
Navi is just another example of the desperate search for more performance on GCN without breaking out of limitations and power/heat budgets. They can't push more out of a single die, so they use multiple of them. While in essence the idea is similar to Ryzen, the comparison doesn't really convince me, because soon AMD will have 3 radically different types of cards out there that they have to develop and support. Hardly efficient. They also go back to the drawing board in a big way while their competitor is continually scaling the same architecture and fine tuning it further, while it still has the MCM option to turn to after that.
We can always hope for the best, but AMD simply hasn't got the time to keep screwing up GPU anymore.
