Rumored Polaris Refresh

There's also a Navi rumor, but it's sketchy.
Quote:First off, there’s a new Polaris family supposedly being prepped for a Q4 2018 introduction. Built on the same 12nm process improvement as AMD’s second-generation Ryzen CPUs, it would offer a 15 percent performance improvement over current cards.

There are only two ways for AMD to deliver this kind of performance improvement, and only one of them makes sense. To improve GPU performance you can make a GPU wider or smaller while keeping the architecture the same, or you can increase the GPU’s clock speed. With architectural changes unlikely, this suggests that AMD would instead simply try to ratchet clocks higher. And who knows? Given that Polaris was the first 14nm discrete GPU GlobalFoundries had ever built, it’s possible that AMD found some low-hanging fruit that would allow it to hit higher clocks. The larger problem is that while a 15 percent jump would give AMD much stronger footing against Nvidia today, it might not compare well against any next-generation hardware Nvidia launches — at least not without price cuts.

Quote:At the XFastest Network event in Japan, ASRock shared some slides detailing its overall graphics card strategy up to February 2019. There are some interesting bits of information that can be gleaned/extrapolated from it. One bit of information that seems to be set in stone is the introduction, come August, of revised versions of some graphics cards (namely, the RX 570 and RX 580 models) under the MK2 marketing - likely revised in their cooling apparatus. That the RX Vega versions of ASRock graphics cards won't be receiving such a revision seems clear as well: there's no reason for the company to withhold information on that. The others, however, are more prone to speculation.
