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.
Quote:According to Phoronix, a new PCI ID, 0x6FDF, has been added to Linux. It’s not mentioned in any database of Radeon drivers or GPU models anywhere online. It’s listed as being part of the Polaris 10 family — in Linux, Polaris 20 GPUs (RX 500 series) are part of the Polaris 10 family as well, which increases the chance that this is a 12nm die shrink. What might we expect from such a part?
A straightforward 10 percent clock increase would put AMD’s RX 580 ahead of the GTX 1060 in every test we ran at launch. Power would still be a significant advantage for Nvidia unless AMD managed to rearchitect the chip along with the die shrink, but AMD would have a stronger position to challenge Team Green in the midrange.

The idea that AMD would pull a refresh like this seemed unlikely back when Nvidia was thought to be launching a top-to-bottom stack refresh. But today, that doesn’t look to be the case. The performance hit from enabling features like RTX is so heavy, it’s not clear if Nvidia can even launch the feature below the RTX 2070, which means Turing may effectively be a refreshed GPU family with a lot of Pascal cards hanging on. Nothing is stopping NV from eventually launching new “2060” cards that are basically rebadged 1060s, and both AMD and Nvidia have gone down this road before.

But Nvidia may not want to take that step this time around. The question for the company is whether it makes more sense to position the new RTX family as entirely devoted to ray tracing and DLSS with the old Pascal numbering system reserved for non-RTX cards or if bringing these other GPUs forward into the Turing product line and labeling them with the new naming convention would confuse buyers. I’m inclined to think it would; buyers are unlikely to grasp the distinction between an “RTX 2070” and a hypothetical “GTX 2060” if Nvidia tries to make the “G” alone the distinguishing factor for whether new features are available. Regardless of whether or not Nvidia keeps Pascal in market or attempts to re-brand older cards as part of the Turing family, AMD may have an opportunity to better position itself in the mid-market.

Of course, all of this is supposition, based on some PCI ID codes for a product family, not actual hardware. But if AMD can snag a win across the midrange for a die-shrunk version of its Polaris family, the company may well go for it. Improving its competitive midrange position is a good way for AMD to win back market share, even if it isn’t competing with the RTX family.
