Yeah, realized my faux pa when looking at the specs listed below it. Thanks for confirming.
Interesting times ahead. Decent 480 AIB models, and the 1060 incoming. Have to admit, the lack of AIB models was the only reason I hadn't got a 480 yet... I really didn't want a loud blower, so tried my hardest to not go and pick one up lol.
I really want to know which cards use decent custom PCB's though. Hopefully do the job right.

970's the g1 has a better 4 pipe heatsink and a more aggressive boost bios and back plate.
The wf3 model has a 2 pipe heatsink no backplate and less aggressive boost bios.
Gigabyte tend to lock the voltage controller on amds.
Locking voltage would make it a bit pointless for anyone who wants to overclock. All the coolers potential wasted.
Thanks.
Funny how these designs rise & fall out of favour, Asus used to be a lot more popular before heatpipegate it seems.

There was nothing special about my R9 380 G1 that I can tell, other than the cooling seemed to be better thant he other models. By nothing special I mean, I don't think it overclocked any higher than a regular 380.
Apparently my cards ASIC quality is 72.1% whatever that means.
I do laugh when I see a card listed as 'Super Over Clock', and standard is 970, and the OC is 20mhz to 990Mhz.

If i finally get a 480 I will be checking out the devil, strixx and nitro. Not sure on the msi variant yet though.

The coolers are of varying quality and will depend on what other tweaks they've made to components and PCBs

Coolers & quality of, any custom changes they have done on the PCB and clocks.

No.this is against a 970 @ 1550Mhz, 30% faster, 10 to 15% faster than a stock 980, a stock 980TI is a good 25% faster than a stock 980.
So the RX 480 @ 1350Mhz is about 15% short of a stock 980TI, it would have to clock to at least 1550Mhz to match a stock 980TI, probably more cuz scaling, if those fabled AIB 1.6Ghz RX 480 actually materialise they might just do it in this game and possibly other DX12 games, Hit Man is probably the one game where it may stomp all over the 980TI as the 390X already beats it and at 1.6Ghz the 480 waaaaaay faster.
But, and i say again through fear of the Gibbo, the 980TI overclocks too, like a trooper.
Are you having a little trouble with the maths there?
You're saying that overclock puts the 970 at 10-15% faster than a stock 980, and you're saying a 980ti is about 25% faster than a 980, which means that 970 is only 10% or so slower than a 980ti at stock.
Now the RX480 is 30% faster than the overclocked 970........ that would put it way beyond the 980ti by your numbers, which I have no idea if they are correct.
Though again it's worth noting that the RX480 is probably limited in max frame rate as it never exceeds 62fps that I noticed and never went below 58fps.
Also the 970 rarely hit 50fps, was at 44-50fps when essentially no action was happening but spent almost the entire time during action at 39-41fps while the RX480 didn't dip under action. So during action when performance both matters more and is more noticeable, the RX480 was a full 50% faster consistently.
Probably also worth noting that in such a scenario the RX480 performance/watt is drastically improved.

Broadly speaking comparing to those numbers a 970 SC gives about the numbers indicated 37fps low 42 fps average as the 970 in the video achieves. The 56mins the Titan X achieves would suggest the RX480 has slightly higher minimums and slightly lower average, if the minimum in the vid was 58fps, either way the cards would be pretty close.

^ According to these taken over a large spread of games.
The 980Ti is 40% quicker stock for stock here
http://www.pcgamer.com/radeon-rx-480-review/
and ~33% faster stock for stock here

Obviously the 980Ti clocks like a monster and the rx480 does not so i can only see that gap widening a fair bit when both are overclocked.
Compared to the 970, the Rx480 seems to be 5-10% quicker according to that spread of game averages ^

no one buys a 980ti today, they are way better off buying a 1070.
No i am basing that on all the information we have so far which is that the RX480 has a HUGE way to go to get the same overclocking capability as the 980Ti (in terms of a percentage overclock over stock).
We've only seen 1500mhz and that was on an extensively modified water cooled RX480 with the power limit set at 300%!.
Yes the AIB cards may have more power connectors but we saw how well that helped on the 1070 and 1080 didn't we...

With all the modifications the guy failed to bother cooling the memory or VRMs, or any other chips that needed cooling(I haven't seen if there are 1-2 other chips that need cooling, there often are).
With their i2c module bus they could control the ir3567 voltage controller.
They did this first with the stock cooler, then with a water block and a 120mm fan over power regulation side. From their software Evc they could monitor gpu output voltage and output current and vrm trmps. As can be seen at 1.328v 1500mhz the vrm temps were peaking 103c
The 6 phases can take 40A each and the mosfets are rated to 125c.
As they didn't increase the memory voltage they didn't need memory cooling,
As the vrm temps were below max temps, then there was no issue with anything that you are saying. The limit was the silicon and architecture and above 1.35v would require serious cooling. On air 1.35v will need a cooler the size of the powercolor 390 or sapphire 390.
Essentially the 480x is a tonga II clocked up over laptop spec.
so what? Do you think that would have made big difference to what they would get on the core?
Do you realistically see ~1600mhz clocks being commonplace on air on these?
Basically what i was trying to say.
On air expect 1350-1400. Maybe a few lucky chips will pass higher but
From the voltage scaling i've seen it seems 1.15v gets 1330-1350.
1.30-1.35v tops around 1480-1500mhz not on air cooling.
