I think I've missed something, but how come 480 didnt have aib cards since day 1 like 1060? (and still doesn't). Almost same situation as when r290 reference throttlers were compared to nvidia OC cards.
I can think of a couple of reasons ~

The stock 480 were AIB/OEM/Apple rejects therefore the card (ASIC) quality was generally lower & hence they required overvolting, at least in some cases, to be sold as 480 & not 470.

The AIB's wanted/needed better quality chips to compete against the 1060 & reference 480, given better efficiency & more OC room they'd sell at a premium & rightfully so, not like the FE crap.

Now that you mention Apple, it struck me that Raja still works for Apple in a way, designing graphics chips for them. Because of the way the GTX 1060 boosts I don't really expect much gain from aftermarket cards other than better coolers. I think aftermarket 480s could definitely match aftermarket 1060s if they are indeed binned better.

I do expect many custom 480's to beat the 1060 FE even in DX11 games, depending on the factory OC; besides that the 480 is also looking like a repeat of the 7970, as in having tons of OC headroom just not on the reference model though

Where do you see them requiring overvolting? Everyone that I've seen talk about their 480 says they can undervolt them for better performance as well as lower power draw. The only overvolting was the stock voltage being set too high.

Well that's what I was alluding to, probably needed to word it better, aside from the fact that AMD have generally overvolted most GPU's, since the 7970, at launch but generally they've also been clocked a fair but higher like the 390/x. The 480 likely has lots of OC headroom with proper cooling, my statement was in regards to the card passing validation as a 480 & that they've just put more voltage than necessary, I'm sure it also helped a lot of lower (ASIC) quality cards pass validation testing. Now whether the voltage could be lowered further on all the cards that came out of AMD is anyone's guess, but someone obviously felt the need to crank voltages to the level that we've seen with the 480.

The Asus seems like it could be quieter but it's also going to be the more expensive one. The nitro should be perfect though if you don't care for the extra things on the asus like the shroud or lights.

I don't know if the Asus will be quieter. 3x smaller fans are usually louder than 2x larger ones, all else being equal. The Sapphire shroud looks to be much more "closed" than the Asus one though. While I prefer that aesthetically, it might adversely affect cooling performance. No way to be sure until they are released though.

I think it's a way that AMD controls leaks. They keep the chips out of the AIB's hands as long as possible.

What is a shroud?

How about MSI ones, would they be quieter? And if so, which of the Gaming/Twin Frozr/Armor is better?

The shroud would be that enclosed case that wraps around the card and cooling vents.

ASUS models have open sides that allow heat to escape the radiators more efficiently, whereas Sapphire encloses those sides, restricting that kind of venting. However, 2 larger fans on the Sapphire really should be much quieter than the 3 small fans on the ASUS (smaller fans need higher RPM to push the same air as larger fans. RPM = noise).

So it remains to be seen which solution provides the best cooling/noise in relation to performance. ...but I think there is already data somewhere with Nitro 390X and Strix 390X, right? I doubt it would be much different.

However, less power draw with the 480 should mean much less heat overall, so both will be quieter than the 390 versions. The relative differences should be comparable, however (Assuming each card is clocked similarly?)

Thanks for the explanation!

I wonder when these will be available to order. I got up early today to check I guess it would start at 9am EST on NewEgg again like the recently released GTX 1060? I wonder if Amazon/Amazon.ca will have any for sale.

The asus won't be available until mid August. The nitro and powercolor no idea either, supposedly July 21 according to the oc UK store.

Cool, the Stix will pull NO power from the pcie slot. Still, it'll be too late to market for me, Nitro it still is.

though that was at 4K resolution. Wonder why they would show that chart?
I'm not sure who would buy these cards to play at 4k. If that's the goal then you have the wrong card unless maybe you turn down most of the settings.

Wow.. Other AIBs are likely the same. a near 20% increase. If its priced the same as the 1060 then its pretty much game over for the 1060.
Perhaps in a vacuum, but so long as Nvidia's brand name rules supreme the 1060 will always command a premium over the 480 & sell in decent numbers. Let's be realistic, that's how it always plays out :|

Showing 1080p numbers would make the gains less important as the base numbers would already be past 60 FPS. When base numbers are in the 30-40FPS territory, any 10-20% increase is needed. Buy now!

Its a mindgame

AMD launch reference 480 with boostclock @ 1266mhz (even throttle down sometimes)

Nvidia adjust their own performance for the 1060 to be a tiny bit above the 480

Nvidia launch reference + AIB 1060 which is ~ +5% faster in dx11, and -5% slower in dx12. (maximum overclock is ~ +10%)

AMD launch AIB 480 with boostclock all the way upto 1450mhz. (unknown how much overclock is possible)

End result: 480 AIB beat 1060 AIB/reference in pure performance, even in dx 11.

1450/1266= ~14.5%
