AMD Polaris 10 XT2 and Polaris 12 appear in macOS drivers

[WYP]

AMD GPUs that are designated as Polaris 10 XT2 and Polaris 12 have been found in Apple's macOS drivers, alongside Vega10.



Read more on AMD's Polaris 10XT2 and Polaris 12 GPUs.

Hmmm... interesting. The name Polaris 10XT2 suggests a dual GPU, but the Polaris 12 confuses me. An even slower GPU than the Polaris 11 chip doesn't make sense unless it's a chip specifically designed for Apple and other small form factor systems.

Polaris 10 was made first and Polaris 11 was made second, so it may be possible that is is Polaris 12 because it is the 3rd Polaris GPU? It is hard to know where it would stand, but it could be a higher end product.

So that's why Vega is named that way? It's not that Vega 10 is inherently less powerful/more powerful than Vega 11, it's that it was designed first. OK, so that would make Polaris 12 potentially anything.

Yeah, it is a strange naming scheme, but it makes sense. Why have a higher number for a lower end product otherwise?

Hard to know as you can't base a trend on two chips. I did hear an AMD rep talk about it like that before.

It could be an APU dude. Maybe Apple have tried Zen?

The polaris 12 is probably dual GPU. "2" being 2 dies.

Edit: Nevermind about the above. I think I figured it out.
XT2 is the dual GPU, but P12 is the refined Polaris 10 that JayZ talked about during his XFX 480 review, where power consumption was much much lower and temps were phenomenal.

Please, call me Dan. Dude was my father's name.

Yeah, I reckon there will be a dual Polaris 10 GPU based on the 'revamped' manufacturing (between 1070 and 1080 performance), and then there will be a heavily overclocked version, maybe with GDDR5X (doubtful though), that will be slightly slower than a 1070. Vega 10 will then be above a 1080 in performance, while Vega 11 will be close to Titan XP performance. That gives AMD a wide range of accessibility, at least in terms of performance. Right now there are just so many wasted holes in the market.

hmm XT2... that sounds like a Dual GPU card possibly. Not sure I like that, well it's not Polaris's fault, it just "could" mean Vega is a while coming yet. That's going to be bad for everyone. ^_^

Isn't Polaris 10 a cut down core? (2304 vs over 2500?) I think if the revision could clock and they could unlock some more cores (RX 485?) it might stand a better chance against a 1070. THAT would require an 8-pin connector though!!

No it's not. It's already maxed out

That doesn't bode well for a revision having enough to compete then with a 1070, unless it's able to clock way higher then it is now. Industry needs Vega to get here seems like.

It could be an entirely new chip that was previously unannounced.

It's probably a revised version. If you read what I said earlier, Jayz talked about it when he reviewed the XFX 480. So new cards like a 485 could come out that is much faster and cooler due to refined processes. This would mean big Vega come out soon, and the Vega to replace Polaris domes out later.
