I just thought I'd bring this up here, resurrect this thread as I have no better place to interject this. While I know Polaris is not a place AMD would think of spending cash, knowing that we see no replacement on the horizon, and that Nvidia is all but surely waiting in the wings till there's a sign of movement of competition there's no use in offering anything truly revolutionary from the green team at the mid-range.
All that said, I was thinking at COMPUTEX AMD might least "drop" we are doing a Ryzen+ to Polaris. Nothing more than a few tweaks to perhaps the memory controller or whatever cheap and quick "corrections" and just say it's going to the 12nm process. I'd consider their inventory GPU's is not in any much of back-log, indicating they could make the change on-the-fly without discounting existing inventories. Now sure I don't know how asking GloFo to move-off the 14nm process, and boost 12nm wafer production would affect output, that could have a lot to do with it. Although, the understanding is 12nm nothing more than iterative improvement (half-node) of 14nm, so most production machines and tools aren't necessarily effected. Given what I'd think it's now almost a year since GloFo started 12nm for Ryzen+ they'd consider ceasing 14nm a good consolidation move.
Now sure such a "re-spin" is not going to make any huge deal on performance or where it sit's in the stack of competition, but given the almost lack of any real news for "Gamer's" this would've been at least a small "nod" they could do and not set-off any real alarm to Nvidia - they can stay their course. A little bit more performance (at least in boost), hold the power envelope, perhaps a slight bump in memory utilization, and put a "bow" on top with a new Driver bump like Adrenalin and Crimson.
I know a "rebrand" and driver hype... but honestly what "Gamers" are hearing now is "crickets" and what seems like for another year, and with more than a year+ of crypto mining and GDDR shortages and the pricing we endured (and they all made decent bank) they need to say/do something however trifling.
