It's obvious that Polaris gets incredibly efficient at the lower ends and proves my theory about the RX 480 being stretched out of its intended performance bracket, and goes in line with what Raja said in that PCPer interview, that Polaris focus was on P11.
Well, your talks are really different from the reality.
RX 470 is a little more efficient than RX 480 but not so much and the 2.8X cake is a lie. The 470 is not even 2X but around 1.7-1.9X on games like Ryse and TW3 vs a 270X.
2.8X is 1060 territory and we're very far from it.
Worst, your Polaris 11 "incredbly power efficient" is a joke too.
RX460 beats 750Ti by a little in performance and have almost the same power efficiency. GM107 (28nm HP) is a Q1 2014 chip, P11 (14nm FF LPP) is almost Q3 2016.
I don't know what happen at AMD but Polaris is indeed a big failure, barely able to face the old Maxwell arch from nVidia, a total waste.
nVidia got a free highway regarding laptops (GP107 will slaugther this thing) thanks to not having a real competitor again.
And this, (BF4 and TW3)
Waow. Around the same power consumption, with a 2X bigger die in size, more than 2X trannies and still around 2.2X performance, It's quite shocking.
AMD is late, really late...
