I wouldn't dare to assume that he just took the results of an aftermarket overclocked RX 460 4GB to deduce price/perf of the RX 460 2GB, which is almost a tier lower performance wise(~20%). That'd be really bad for this web's credibility.
I'm kind of annoyed how many sites lately side with the "underdog" and try to put its products into a better light on the expense of the consumers, this whole Polaris line up would be quite the epitome of it. They aren't doing the consumers or the hardware scene any favors by doing this, quite the opposite actually. If the underdog isn't even trying to offer a better deal than the competition and his product strategy doesn't make any sense, it's time for him to go, he doesn't deserve to gain market share like this and normally wouldn't be able to, don't support this behavior or it won't get any better moving forward.
I don't know if the hardware sites even care anymore, it's just the business as usual year after year, just some companies trying to milk the consumers with the same generational performance leaps even though the technology and manufacturing costs change significantly. I'd probably get disillusioned and apathetic as well, why even risk aggroing the wrath of fanboys if you don't really have your own skin in it, just recommend that crappy product and move on...
