Bonaire reachs 1,5GHz?.

Bonaire has a high-speed IMC like Tahiti. There are SKUs withs up to 1.625GHz / 6.5Gbps data rate.

M400 series' specs are already in the website.
Those do seem like Tonga and Bonaire rebrands.

i can't dig around right now, since i'm on a phone in another country, but IIRC it has been stated that AMD was responsible for the physical memory controller design when they co-developed HBM with Hynix. That in mind, why on earth would they use 3rd party memory controller in Fiji?
Yeah your probably right.
I am probably conflating this due to Northwest Logic working with SK Hynix and were one of the very first with an HBM controller completed; they had their controller ready back in Q1 of 2014 and also proven using Hynix modules (way before they were available to market).

Anandtech confirms they're all rebrands:

Since AMD has placed Tonga as Radeon M485X and Bonaire as M470/X, I imagine Polaris 11 will be Radeon M480/X and Polaris 10 will be Radeon M490/X.
Also, they seem to confirm (or guess, maybe?) that Topaz is, in fact, a GCN3 GPU. Oland is a GPU from early 2013, so if this is right then Topaz really is a new (and rather obscure) GPU.
On a side note, it'll be really weird if the M470 consumes substantially more power while performing substantially worse than a M480.

Yeah its gonna be a really weird and confusing mix. Unless Polaris mobile lineup is not M400.
Still, AMD has been involved with HBM design since it began, and it's not the first memory standard they (co)developed. I see no reason why AMD would use 3rd party memory controller in anything
The May 18th Polaris presentation won't disclose anything interesting:

I was under the impression that 10nm would only see use in the mobile space, with high power chips waiting for 7nm. For TSMC at least, don't know with Samsung/GF.

What's the point in it then?

Let me get this straight. AMD announces this thing on twitter on their main account https://mobile.twitter.com/amd/status/731549678341398528 to then announce on reddit that they are not going to show/disclose anything substantial?!?
Who is running their communication department?!

It is incredible how AMD can employ such great and amazing engineers, and yet screw up in other departments (not just marketing).

I wanted to say the same thing.
If this event was all along a professional meeting to brief their channel and partners, so why do you announce it publicly ?
They've just created hope, hype and buzz for nothing. Even worst, now people is frustrated.
I have no idea how such big company can be so incompetent in marketing, it's a disaster, the kind of example you can teach in school in the category "not to do"
GCN would definitely need more VGPRs per CU. Nvidia doubled VGPRs per thread in Pascal, and they have less VGPR pressure.
Is is hard to write complex shaders with good occupancy on GCN. I mostly blame the compiler (it's does aggressive load->use latency hiding, wasting lots of VGPRs). Hardware with more registers would make the software much less of a problem. It doesn't help that GCN has the widest waves of modern GPUs and executes instructions in 4 cycles (IPC per thread is low -> registers are allocated for long time). GCN scalar unit is great, and hopefully Polaris extends it further (so that the compiler can better offload coherent calculations and coherent data to it).
Finally Polaris is out of the wood:

NV unveils GPU that might commonly clock upwards of 2.1+ GHz.
