the sapphire 480 nitro looks pretty good. has that simple clean look like the evga cards have. i like it http://videocardz.com/61794/sapphire-radeon-rx-480-nitro-detailed-some-more

By the way, I'd like to congratulate everyone on a focused and civil discussion. Venture out to other forums and there are quite a few battlezones. Fun to read for a few minutes, but that stuff can get grating after a while.
 

Hopefully it has an 8-pin or dual 6-pin connectors.

It does seem like a race for AMD at this point, they only have a week or two of free reign. But without good custom cards available and the power issue, they are not maximizing the opportunity.
 
Really hoping it does as well.
I get the feeling that there is still the potential to knock out really cracking custom 8GB RX 480s... with a couple of 6-pin connectors and big beefy coolers with custom PCBs and binned chips.
As long as the Bios etc. is properly revised for us overclockers (adequate increase of power limit, voltage limit and no power draw issues) I think we could see some sweet results yet from Polaris.
 


I think the more obvious solution, rather than limiting power, would be to adjust the distribution with drivers so more is on the PCIe cable instead.
 


report comes from product listing on overclockers.uk https://www.overclockers.co.uk/detail/index/sArticle/61887 it says it has an 8 pin power connection and more power phases. "The card is designed to run cooler, quieter and have improved overclocking ability due to improved power phase and 1x 8-pin connector" but that's all it says. i think at least an 8 pin is a given for the custom cards except for reference based low end ones.
 


people have many opinions of course. but to me both are about the same actually when it comes to sponsored title. just that nvidia have more resource than AMD so they can work with more developer. this is including non triple A titles. when dirt showdown using forward+ engine that extremely favoring AMD architecture did people rage about it? no. but why people raging with gameworks?
 
At just under £250 I like the price as well.

Nvideas' GTX 1060 will really need to match the RX 480 on price, as being more expensive yet a bit faster won't work for them in this particular 'budget' market segment - in my opinion.

Can't wait for the benchmarks.
 


if you ever see few of his posting in the past you will know why he react like that.
 
btw case like this is one of the reason i'm not rushing buying new cards on release. remember the fan spike on those 1080/1070? good thing such problem is fixable by driver. in this RX480 case AMD probably can fix them from BIOS or driver. just that i think AMD probably should have gone with one 8 pin config from the get go. some people actually speculating if this is related to why there are rumors of AMD polaris can't clocked really high early on. remember when Raja mention that they are confident that they are few months ahead of competition? Nvidia are very quiet about pascal. they don't even throw any hint during CES. going as far as using GTX980 module on drive PX 2 because they don't want people to dig pascal info from that. AMD probably did not expect for nvidia to release pascal so soon on the market. and after looking at how 1080/1070 perform they probably push the target clock higher. i still remember 270X was rated at 170w or so. but during typical gaming the card actually consume about the same as GTX660 in typical gaming (anyone interested can look at TPU power consumption chart). so when AMD mention 150w for the card me and many other expect RX480 would use a lot less than that. for the optimistic one they assume RX480 will consume around 95w on typical gaming. me i was expecting around 110w for typical gaming scenario. when i see TPU reporting the power consumption was over 160w even during typical gaming i was surprised actually.

board partner will surely fix this issue because they have more control in designing their own custom PCB. as for the reference i'd expect this issue will only affect the early batch of cards.
 


The 6-pin wouldn't have been a problem either, if AMD could have just pulled more power on that instead of through the PCIe slot.

As for the pictures, I absolutely hate how GPU brands always try to avoid showing the PCIe power connector(s).
 


Yeah, I read that the difference between the 75W 6-pin and the 150W 8-pin is the 2 x additional ground cables. So there's not any additional power supplied through those extra cables.
 


I read about this on release day (was mentioned a couple pages ago), AMD even confirmed it could be done, however also said theres no chance in hell of them releasing the BIOS... Which means we should have it in about a week. Its supposedly why 8gb cards were so common and 4gb was in short supply. My Microcenter had about 30 8gb cards and 2 4gb cards.

 


Whilst an obvious solution the reference card still seems to be consuming more power than the PCIe spec allows for.
