The strix model is slower than the rest and matches up with TPU as well. This card has terrible pricing. If mining cools down, these cards are going to sell way less cards. Too much cannibalization going on. You can tell by the messed of price to performance vs the rx 480 4gb, that AMD never intended to price their cards this low. The rx 480 4gb is clearly the best price to performance vs the rx 470 and rx 460 which is stupid considering it is the highest end SKU from AMD for Polaris. The problem with the rx480 4gb is that it is going to be a rare card, atleast at its 199 MSRP.
This just seems like a poorly executed launch overall and AMD didn't get close to a 2.7 increase in performance per watt they were advertising.
At 150, pricing makes sense, since the cut down version is supposed to offer better value. At 179 or in most cases 200+(street price), it is badly priced vs the rx 480. But 150 is probably below cost for AMD.
