AMD Polaris Thread: Radeon RX 480, RX 470 & RX 460 launching June 29th

[PeckingOrder]

tell that to all these R9 290s mining cryptos at 94'C 24/7

I dunno, it'd certainly make me uncomfortable and worried about the lifespan of the card

I like keeping my GPUs for ~4 years and then selling them in a good condition

Then you'll have to wait for the aib versions. 200 only goes so far I guess.

 

[OILFIELDTRASH]

Me personally I will pick up a $200 480 ref 4gb version. I just don't see the point of the $300 aib 8gb version. Id just assume wait for a $380 1070 that would smoke the 480. Yes there are no $380 1070s but I'm sure after the initial rush they'll get to msrp eventually.

Any idea what the ETA would be?

~2 weeks would be acceptable in order to avoid this cooler, but I'm kinda itchy given I'm using my iGPU atm (might have jumped the gun selling my HD 7850, I didn't think there'd be only ref cards on the 29th)

 

[coercitiv]

That's in line with what I saw in chinese forums. If 6-pin is the limiting factor, then this card is not using only 100W in typical gaming loads.

Let's hope those chinese forums have at least some valid info roaming around, otherwise we'd still have Polaris chip unable to pass the 850Mhz validation from one month ago, but overclocking to 1600Mhz+ one month later.

Gotta love both trains!

 

[Shivansps]

And you know this to be the case, how exactly?

Because you can run it out of spec, and worse case scenario you gona melt the connector and/or cables, but its never gona limit OC.

 

[Zstream]

I hope it's not another r9 390 devil 13

What was wrong with that card? Legitimate question.

No clue there hasn't been any mention other than there will be some but we don't know when yet.

I may do the same as much as I would like an AIB version. Then again if the 1070 does drop to "MSRP" that could also be a contender. I doubt stock will even last on the 29th by the time i get a chance to look.

Bonus:

- Radeon RX 480 OC @ 1360 MHz / 2050 MHz (3DMark Fire Strike Extreme GPU Score): 6104
- Radeon R9 390X OC @ 1120 MHz / 1700 MHz (3DMark Fire Strike Extreme GPU Score): 6157

The 100w was never more than speculation and just popped out of thin air as i can tell. Its a desktop part. If it uses 130 or 100w makes zero practical difference. And there is a reason the aib go 6 plus 8.
We know the finfet process have a limited scope for voltage vs freq unlike say Intels old 32nm. Its all tradeoffs. Efficiency plays a part and cost is certainly one of them.

Polaris is the highest priority because its also consoles and imo low cost is at centerstage here. Its 200 usd cards. The idea of some 4850 vs 280 situation comming again is far out.

Whilst GPUs are obviously capable of drawing 75W from the PCIe slot, AMD tends not to do so, instead relying on the connectors as much as possible.

Even the Fury X only draws about 10-11W over the slot.

So the 6 pin connector may very well still be the main limiting factor, unless AMD has decided to change their design philosophy on how much power they draw from the PCIe slot.

 

[trane]

150W over 6-pin is just a certification / specification. In reality it can draw much more power than that. Either way, that's not the limitation.

The fact that you can do so doesn't mean that AMD will allow the card to do so. I can't think of any reference card that was ever allowed to pull more than spec out of the box.

150W is for 8pins. 75W is for 6pins.

The Fury X got 2x8pin aka 300W input directly. The Nano for example used 200W+ with a single 8Pin. Hence drawing 50W or more from the slot. Same goes for Hawaii cards. The Fury X is rather an exception.

The cards is build for the temps. 80 is zero like ZERO problem for the gpu dies lifespan.
My guess is the solid capacitors that is the weakest link is even rated for 100c but even if they were 80c rated with a die temp of 80c they will certainly be kepts under 70c all the time and last 10 years.
The blower is probably better than the 290 ref. And will only have to disepate half the energy. For resulting temp and the components lifespan the difference is not 100% but probably a factor of 100. If a solid quality capacitor is hold firmly within its working temp it easily last 10 years 24/7. If it doesnt well it possible brakes within a year but it will not happen here. Its damn near impossible.

 

[R0H1T]

150W is for 8pins. 75W is for 6pins.

He probably meant 75W through 6 pin combined with 75W via pcie slot, for a total of 150W, which is not a hard limit since cards can draw even more when under stress.

 

[krumme]

The fact that you can do so doesn't mean that AMD will allow the card to do so. I can't think of any reference card that was ever allowed to pull more than spec out of the box.

You can take 150w over the 6 pin. Same as 8 pin.
Hell i even ran a 6 pin oc 7850 with a cluster [redacted] of several molex from a 300w passive psu from the stoneage lol - well that model is hardly a viable business strategy.

The 6 and 8 pins is designed to safeguard the psu and card and that you can use your new gpu and that your ps is build for it.
So who in their sane minds sells reference cards that out of the box with some frontend oc breaks that barrier. Never.

Profanity isn't allowed in VC&G.

The Nano doesn't draw 50W from the PCIe slot it only draws about 20W, and about 165W from the PCIe connector. So AMD will even break PCIe spec rather than draw power over the PCIe slot (guess my last post has an answer now).

As far as Hawaii goes, it draws about the same 20W that Nano does, so no the Fury X is not an exception.

So if the average power draw of the RX 480 is 100W, it would probably pull 75-85W from the 6 pin and 15-25W from the PCI slot.

You can take 150w over the 6 pin. Same as 8 pin.

The fact that you can doesn't necessarily mean that you will. The card still wont draw anymore power than the BIOS allows it to.

So who in their sane minds sells reference cards that out of the box with some frontend oc breaks that barrier. Never.

Turns out that AMD actually already did this. The Nano breaks the PCIe spec (drawing 165W over an 8 pin) and that's before you even start overclocking the thing.

What cards is that?
My 970 had 6 plus 8 and it wasnt for fun. I know the "stress" happened there. It had high spikes as tomshardware showed but it also had to 6 plus 8 to handle it.

7850 that was 6 pin was more like 100-120w.

It's not just AMD, Nvidia does this too, although to a lesser extent.

 

[sze5003]

Do we know if these will include for example any adapters? Like HDMI to dvi or display port to dvi?

I am also sure its a bios thing. Like you can hack 970 bios to get more power headroom.
Surpriced they braked specs for 8 pin even if it was only 10% on a reference card btw.
I also dont understand they dont wait to launch so the aib can do it, but i guess they were hell bend on this q2 deadline. I think its pretty stupid.

Take the 950, sans power connector, for instance & it can draw more than 75W just from the pcie slot.

I'm sure you can find others, that go over spec for the pcie slot &/or 6|8 pins.
Not saying a particular GPU, or AIB model, does that but it's very much possible & plausible.

Its not a reference card.
The 290x ref as i recall only took more than spec if you flipped the switch.
It will be great if amd didnt limit the ref cards at 150w i just find it very unlikely.
I have personal no trouble punching 200w on that 6 pin if needed. Doesnt take me 2 sec to get the slider there. Lol.
