In his stream (https://www.twitch.tv/buildzoid/v/75850933) he explained at 54mins how AMD mocked up the power delivery on the reference card. I hope for much better OC results and power consumption on custom PCBs.

That isn't good if they've bypassed power distribution and hardwired each domain to a different connector.

I like his confused "Why the **** would you do it that way!?!"

Calm down lads.

Simple really, a few the extra fps but with benefit of lower temps and avoid throttling for more consistent performance.
Its surprising sometimes when you look at cards like even the beastly Zotac 1080 Amp Extreme how few extra fps in many titles is only gained over the stock/boost.

Same thing happens with CPU OCing, but people get blinded by the bigger numbers in their Afterburner.

This is just all wrong, I don't know where to begin. Despite what Gibbo says (hint: he wants to keep selling 480s and doesn't seem to have a good enough grasp of the issue, not his fault, half the people here are posting rubbish and trying to cloud it) this isn't going away. This tosh about minimum IS bunk yet you have the gall to talk about "debunking". If you don't know what you're talking about and are just trying to carry water for AMD out of some butthurt fanboy sentiment, please just be quiet and let the experts hash it out. Someone from pcper even posted here trying to give you the straight dope but you put your hands over your ears and screamed LALALA.

Funnily enough this would have been sorted already if there wasn't so much FUD flying around from the red team trying to cover it up.

So your saying im wrong and tomshardware is wrong? And Gibbo who has a lot of renown would not stick his neck on the line and say its a no problem, just to sell more gpus if it was really a problem. It would look bad making a statement like that if it was not true. Like i said its a non issue. People exaggerating.

Don't make me out to be some fanboy thanks. I love hardware despite where it comes from. I'm literally dieing to hear what Vega and big daddy pascal bring. Although from the state of things atm i feel big pascal will be the way to go but will see.

It's just annoying seeing the same people with any ounce or opportunity to pounce on AMD and spew crap. Then never see those same people when there is something that happens to nvidia take the same way of "discussing" things. Rather they defend to their dieing breath.
Ohh FYI id never take much notice of pcper due to their bias.

True and turning some settings down from ultra - high would do the same thing and likely be unnoticed.

I really like this YT channel for comparisons:
The reality is gaming on an RX480 especially with 1080p for many will be very enjoyable for such an affordable card.

I'd be careful of saying no problem - the cards can get close to the max safe amperage for the gauges involved and when talking about overclocked + crossfire you can be potentially talking about in excess of 100watt over nominal spec through some parts of the motherboard which will demand a lot of the relevant VRM, etc. cooling.

Most likely scenario worst case is thermal or current protection kicking in and shutting down the system but you never know.

EDIT: If I'm understanding the video linked above correctly then in the rare event of partial failure of the pci-e 6 pin source you could potentially stress test your motherboard's ability to cope with over current :s

Well going by the guys stream, he managed to get a watercooled reference rx480 to 1410mhz stable on core with fury x performance from the firestrike numbers. he couldn't get it past that even with modding it with more capacitors to smooth the voltage.

he tried to volt mod it, but it appears to be a pain to do, so he didn't manage in the end.

Wow
if any non ref card after OC can achieve Fury X performance then it is going to be a BIG HIT from AMD
it is a very big jump from 390 to Fury X performance

There's always the (high) possibility that it's power limited and the AIB's with 8 pin power will be able to go further.

Sapphire said the card didn't really need an 8pin.
Seemingly the card isn't power limited, it's something else going on.

If the guy who soldered bits to the cards is right then instead of traditional power distribution they literally hardwired half the regulators for the core to the pci-e slot, half to one of the 6-pin connections and the memory to the other 6-pin. Not sure if that is due to the card being originally intended for another platform, to keep costs down or what but it is going to have some interesting implications if so. Also means you can't just slap an 8-pin in there and take advantage of it.
 
Just realised my current 6870 has two 6-pin connectors, thought it was just one for some reason. My Dell OEM PSU doesn't have an 8-pin connector though so that'll limit my options slightly. Presumably there'll be AIB versions of the 480 that keep the 6-pin?
