Based on everything I've read, it's a very minor refresh of the Polaris 10 chips in the 480 and 470 going into the 580 and 570. It seems akin to the refresh we saw moving from the 200 series to the 300 series, so expect better thermals and slightly higher clock speeds.
We've also seen information about the new, smaller Polaris 12 chip which is meant to power the 550. Sadly we've seen no information yet about the 560, which will hopefully use a fully-unlocked Polaris 11 chip and be good for gamers on a tight budget.
In other words, don't be confused by the new chip codenames: it's just a small refresh, based on an iterative improvement of the existing Polaris chips, but should probably extract about as much out of them as we can now expect.
These cards are still for mainstream gamers. For those needing gaming beyond 1080P or who need higher refresh rates at 1440P, Vega should be here by 2017-06-30 at the very latest, assuming AMD stays true to its H1 2017 launch.
Technically the GPUs in the R9 390 and R9 390X were new too. Unless there is some CU increase(the XBox Scorpio GPU has 44 CUs),it looks more like a refined Polaris 10.
Read that and was reminded of the X1950XTX from years ago, the first card with the GDDR4 memory. Makes me think the RX580 will just be something akin to that refresh, with nothing really new about it (just a bit faster).codenamed 'Polaris 20 XTX'
