I think this was AMD's intention. Provide the masses with a basic great 1080p card for a low price, so the reference design was never meant to hold a premium. AMD probably told the AIB partners to go nuts with their versions of the card, so here AMD provides a great base MSRP for AIBs to start with and then when you have companies going over the top like this:



https://rog.asus.com/23792016/coming-soon/asus-republic-of-gamers-introduces-strix-rx-480-graphics-card/

You really have to wonder what the performance on that card is going to be compared to reference. They are basically taking designs that were originally made to handle a 1080 or 1070 and using them for the RX 480 here.

It seems rumours may have been true about Polaris 10 and that it will cover a huge range of price brackets ie $199-$299

Basic and cheap, power/temp limited card for $199-$229

Then AIB cards up to $300 that actually warrant the higher price due to a much larger level of gaming performance.

Not only due to the increased clocks and no throttling, but the chip itself seems to be scaling very well.

We could see a 20%+ increase in performance?

I'm excited to buy one of these AIB's that's for sure.

I'm more curious to see what they do with the board itself, because you can always just slap on an aftermarket one, if it's just the cooler that's causing all the problems.

I agree that we should see a new side to the RX 480 once the power/temperature items are brought under control. thumb.gif

Wow it makes sense but i had not see that highlighted before now .. I guess i've had too many years of custom bioses - boost disabled bioses etc lol . That would explain my TXs making electrical noise in ROTR in 4k then , working hard at 80-99 % usage in sli (1530mhz @ 40c so i'm treating them nicely still).

Still i guess if the AIB cards can just open up the doors, you could see Fury - Fury X performance depending on the game . In lower resolutions it might exceed them even. On the AMD side anything up to Fury X could really be covered by AIB 480 OC performance then.

I wonder if it isn't bandwidth starved too. TPU managed to get pretty much 1:1 scaling - 5% core OC + 13% memory OC = 5% improvement in games.

Obviously I can't tease out how much each component is contributing, but if core OC is scaling 1:1 with performance increase, that does make me think.

So far I believe a custom air cooler (like an Accelero) did 1425MHz and I believe an H100 modded card did 1480MHz. So there is definitely limitations with the reference cooler.

But it also seems custom PCBs will help the card out more, because we also see the power limitations with the reference design.

So earlier today I decided to go nuts and buy a 3rd RX480. They estimated around 130-150 wattage per card so i figured i could pull 3 of them off without buying a new power supply (750W). I'm too lazy to have to redo cable management so this seemed like a fun test and a time to answer a question that was never asked.

I had some crossfire/trifire issue and 3dmark only used one card. I had to go back to work so i just left the computer idling all day and hoped my house would still be there. It was surprisingly considering the cars idle at 40-45C with the room at 74F

Turned out CCC disabled crossfire so i just re-enabled it and good to go. I ran 3dmark while paying attention to wattage and temps and the max my cards drew EACH was 131 watts. I took a printscreen but lost it during the 3dmark screenshots i was taking for results. Tempatures between all the cards was between 70-80C. Mainly staying in the lower 70's surprisingly. (All stock/automatic settings)

Firestrike Ultra Results:
http://www.3dmark.com/3dm/12832894
SCORE: 6,689
TL;DR: Better then 980s in SLI, 20% faster then 980s in SLI?

Pricing (Micro Center Pricing, Cheapest cards I can find of those types)
3x RX480 - $749

Games that played great no problems with Crossfire and now Trifire in 4K: GTA V, Overwatch, Hearts Of Iron IV
Now gotta install my H115 and some other goodies. Should I even try to Quadfire next? also sorry, no fire.

Its power delivery unfortunately .. and most likely the worst of the gpu pool so poorer asics , eg binned ones for AIB cards. Sure temps help but i don't think ref is going over 1420 (max i've seen) very often.

Don't get too carried away, guys. We're probably not going to see Fury X performance out of an AIB RX 480. 1500mhz is about a 10% OC increase over the currently top overclock for reference cards. That's roughly a GTX 980 level of performance. The Fury X is a class above the 980.

Overclocked reference cards are already making it to Nano levels, so Fury/Fury X is not too far off believe it or not.
