As for the information well... it's scattered all over the place, don't feel like hunting a bunch of it down and condensing it here. There's speculation on it even outside of AMD and Nvidia such as TSMC's 16nm iPhone 6S and 6S+ SoCs vs Samsung's 14nm LPE process. The consensus is TSMC just have a more efficient/superior process currently. Of course AMD could of also just dropped the ball with Polaris too..

But i think the fact that AMD are using TSMC for their high performance chips is telling.

AMD switch vega to 14nm finfet awhile ago.

I can't find the interview any more with Raja but probably since May, AMD indicated they were using 14nm finfet for Vega as well.

does anyone know the power draw of the non-oc nitro+ 480 8gb and the oc version?

i just read this review from eteknix and they listed the total power consumption with the nitro+ oc 480 as 302 watts with a stock 5820K. if we take 80 watts off that's around 220 watts for the nitro oc 480!

from what i read the oc version uses "binned" chips. would the non-oc nitro+ 480 which has a maximum boost of 1306 draw similar to the oc version then if the oc is just using binned chips that draw the same but run at higher clocks?

that be pretty insane if the 1306mhz version draws 220 watts in something like heaven. that's just 20 watts less than the 390 they benched against as well...

The 5820K is rated at 140W TDP though so I wouldn't just minus 80W for the total system power draw. The Nitro+ OC would draw around 180-200W I would imagine.

yeah the 5820k has a 140 watt tdp but usually under loads like heaven its not taxed enough to reach its full tdp even if its set to run at 3.3ghz 24/7 with manual voltage.

i can understand 200 - 220 for the oc version but i hope the non-oc version draws less. much less than that.

so did any reviewers manage to get more than ~1350-1370 OC on the 8GB Nitro ?

you don't know what a true rip off is

where i live i have to pay 4X more because of the exchange, this is fine then some brain dead decide to add even more make the card cost 5X or near 6X the price you guys pay in US and make RX480 a not so good buy when gtx1060 is just a little more

Meanwhile, their RX 480, 175W card, needs some crazy 2200 RPM to keep itself at around 75C. What is going on here? It just lowered reference temperatures by ~10C while keeping the same horrible noise levels...
Sapphire doesn't get it, you should hear the Sapphire Sunday stream they are just pulling out crap out of a hat excuses and stuff like setting any OC in the driver voids your warranty. The fact remains that Nitro is power limited due to low power limit and the cooling leaves a lot to be desired which in some way may be because of the node shrink and thus the GPUs are harder to cool, after all 480 is 232mm^2 of 14nm and Fiji is 596mm^2 of 28nm. You can see the massive area and density difference. It's the same with CPUs the smaller the node and chip is the harder it is to cool. Maybe the cooler is comparable to 380x cooler, who knows I don't know the dimensions but if they have designed the 480 cooler for 150W instead of 250W then of course it's gonna run hot and loud.

They skimp on VRM's all the time, in almost all their products. The results can mean the death of multiple computer components.
I honestly blame you for that one. That's a cheap motherboard. Any brand's cheap products will compromise on some things. You'd be hard pressed to find unhappy MSI customers who purchase their high-end models ($150+ mobos and gaming X / lightning graphics cards).

I mean, i hope you're not using that $80 MSI mobo as reference for comparison with your high-end Asus mobo. That would be just disingenuous.
