Fury non-X dude. Nano is only about 6% more efficient than Fury non-X.

I understand what you're getting at though, but as I said, that just makes things even worse. If AMD has to push P10 to its limits and break its efficiency just to get 970 performance, this doesn't bode well at all for the high end stuff they have planned.

The only saving grace for AMD would be that 16nm FF allows them to push Vega to higher clocks, as GCN scales much better than both Maxwell and Pascal. If the clock limitation is due to GCN, we will continue the current trend in the GPU market until AMD can afford to design an entirely new architecture, which is bad for everyone!

It matters in a subtropical climate with relatively expensive electricity. I'm not referring to the card's consumption but the constant air conditioning required during gaming.

Sure, power consumption doesn't matter, in winter time when the furnace is running. In the middle of summer, it matter a ton, especially when you have to run air conditioning. I guess if you aren't paying for electricity and you live your mom's basement, then it doesnt matter much. For every extra watt, you need 3 more watts of air conditioning to balance out the extra heat. Thats adds up to lots of money.

People are so focused on p/w its insane, and they're not even focused on that issue properly. To properly judge the RX 480 you have to compare it to what its replacing in the same arch, and its a very nice increase in p/w in that scenario.

So the p/w is actually good for an AMD card, but AMD is behind nVidia in p/w and has been for a long time. As many keep stating GCN =/= Pascal/maxwell.

So moving on from that "issue" thats actually good for AMD, why don't you look at the performance/Price. P/P is where the RX 480 literally nukes everything else on the market. Go over to AdoredTV YT channel and watch that video. Guy is crazy unbiased and he calls it as it is. When you see the P/P of the RX 480 its kind of mind blowing how good it is.

When was the last time you got this tier of performance at anywhere near this price at launch? It's been a very long time. This card is by no means perfect, it has some obvious issues, just like any product, but it is an obvious winner.

- GCN =/= Maxwell or Pascal In terms of architectural components
- GCN has always had worse P/W than nvidia counterparts
- From Grenada/Tonga/Fiji P/W is up 1.77x, which AMD stated in the PR slides months ago that P/W increases were approximately 1.8x (special cases up to 2.8x)
- This is a huge step forward in P/W for AMD; THIS CARD IS STILL GCN, with minor tweaks
- This card is in the price bracket of the 380x and GTX 960, in which the RX480 is SIGNIFICANTLY faster
- The price is good
- The P/W jump is comparable to Nvidia's for their OWN architecture; both being attributed mostly to node changes
- AMD made not a single official statement hyping this card to be anything more than what we got; all of the hype blame rests on you as forum users and the rumor mills, NOT AMD.

This is a good card, at a good price. Many people expect the 1060 to drop soon, but until then Nvidia doesn't have a new direct competitor which is good for AMD.

It's sad that so many users are posting drivel when many guests will come view this site for information and guidance, and be so horribly mislead by nosensical and borderline bipolar comments being made. This card is by no means a failure, and as far as I see this almost exactly what AMD told us they set out to do.

Re bold part: the problem is, people have no problem waiting for nVidia, but trying to get them to wait for AMD is much harder. AMD needs to get AIB 480 cards out the door ASAP so the reviews will look much better, and minimize any disruption 1060 would bring to the scene.

Also I don't blame AMD for hyping (because quite honestly they've said very little), and as I've said this card will serve its intended segment just fine, BUT "this is a huge step forward for AMD" just isn't going to cut the mustard when you have fierce competition.

Also I looked up the efficiency numbers, and

It matters because if P10 is 970 performance at 150W, what kind of TDP would AMD need to reach 1080 performance? How about 1080 Ti performance?

The RX 480 is a good design. It seems obvious that that 14nm silicon is garbage for GPU's. Very foolish to not use TMSC. Thats probably why its so cheap.

We got this kind of performance but at $350 with HD 7870 back in 2012.

Around 160 watts maximum load? No. Not even close to make any substantial difference.
