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

[DisarmedDespot]

I've been without a card since April. Mh. I want a 480, but unless the reference cooler is fantastic, I'm waiting for AIB custom ones.

Now thats the charming part about perf/price. You can compare hardware of different price brackets. You do not need a direct competitor in the same price bracket to make this comparison meaningful.



There is no hard limit on die size. For each product architecture you make very individual decisions based on the requirements.



You fail to understand that going wider instead of higher frequency is as real architectural improvement. Where the heck do you get the idea from that only maximizing perf/area is an improvement? For higher perf parts you are going to make different architectural decisions. If the die size is going to hurt your business model more than the perf/power degradation, then you go for higher frequency. It is all about product requirements going into architecture.
Do you have the slightest idea how a SoC development process looks like? I can tell you, that you don't put engineers into a room and tell them to come up with an architecture which maximizes perf/area in order to "improve". It is a very multi-dimensional optimization problem at hand.

I heard you the first time a few days ago where you said the same thing, and I already acknowledged or doubted every point you made in my older posts. If you have numbers to offer for fun speculation based on history and rumours please put forward your guestimates, otherwise there's no room for discourse with you.

Looks like another hype about to derail...

"AMD Radeon RX 480 Allegedly Stable Up To 1340 MHz in 3DMark Firestrike
http://wccftech.com/radeon-rx-480-thermal-tests-leak/

From what I know is that RX480 can get slightly 10% more performance after overclocking, didn't told me the clock speed he got. (not same leak as the news, this is personal one)

Matches what NordicHardware said:

NordicHardware during the day discussed the overclocking potential of the RX 480 with its own sources of AMD's partner manufacturers and there is talk of potential performance increases of around 10% by overclocking. Which matches quite well with a rate increase of more than 10% if one speaks of 1266-1400 GHz frequency boost for easier overclocking. In other words, no stunning performance gains by pressing Polaris 10 circuit, but nevertheless a noticeable difference.

Looks like you are trying too hard to derail it.

We've already seen XFX RX 480 shipping with 1328mhz. If you think 1340mhz is the max OC...

I didn't say what was the clocks that he got, perhaps was more than that, but the real performance just above 10%.
Not trying to derail it, but I know what's real and I know some people might get disapointed.

Its a great card, but looks like people are expecting too much, 980 / ti performance even 1500+ overclocks in most cards stable..

For 199USD is amazing card, just keep it real.. it wont beat or get 1070 even @ overclock. Unless its massive one I guess :sneaky:

why not wait for benchmarks? how are you so sure that the guy is right? how are you so sure that silver is wrong?

And perfectly matches words, and rumors that 1400 MHz is max possible on 6 pin connector. When you add 8 pin to it, you are able to OC much more the GPUs.

 

[lukart]

Well, if my friend has the card probably he knows a bit more than most of the forum members.
But again, don't know the clocks he had the card on. Just said RX480 gained a bit more than 10% performance with overclock.

 

[Silverforce11]

This is that NH article translated:

"Boost frequency of around 1.4 GHz will be fully viable with simple overclocking while with extra excitement and a little more serious work to reach the 1.5 gigahertz frequency boost with traditional air cooling."

What this tells me is 1.4ghz OC is easy & simple. 1.5ghz will require extra work, such as voltage modding.

Unless AMD have changed the way GCN clocks and OC work, you need to manually adjust the voltages if you want to maximize the OC. Doing OC of GCN on stock volts, will get 5-10% tops.

 

[Eymar]

I can't wait! I want to know now! Seriously though if ~390x is baseline performance then $230 for 8GB is a really good deal. If 6+8pin models come in at the $250 I'd wait for those models. It seems like perf/watt will be the big factor in how video cards will be priced in next few years so 480 should hold it's value too since it's initial price point is low.

crap amd's new cards in trouble from what those guys are saying
nv is going to unleash kepler on them

Nvidia overflowing Kepler stock is also AMD's headaches

The problem for AMD is that Nvidia has overflowing stocks of the GeForce GTX 970 and GeForce GTX 980 graphics card that you want to get rid of before the introduction of the new Pascal card in the middle class. Depending on how well the RX 480 stands up against the GTX 970 and GTX 980, Nvidia can temporarily versus AMD's Polaris-launch with further price cuts on their outgoing short while completing their own Mid-GPU GP106.

 

[Silverforce11]

We often see folks say AMD is terrible at marketing and hype... but seriously, this is the most hyped launch in a long time. The interest on tech forums and social platforms (neogaf, reddit etc) is intense. All eyes are on Polaris.

It looks to me the approach of keeping silent but seeding conflicting leaks over a long period of time generate this attention train that keeps on building.

Polaris RX 480 was recently a trending search item on search engines!

In a few more days, we'll all find out if it delivers, under or over.

 

[itsmydamnation]

there isn't a lot of heat sink on the 480 so it makes sense that on ref you would hit a heat wall pretty quick once you touch the voltage. The interesting things will be how far and you push the voltage and will clocks keep scaling with voltage. A AIO solution could be interesting depending on polaris's behavior......

This is that NH article translated:

"Boost frequency of around 1.4 GHz will be fully viable with simple overclocking while with extra excitement and a little more serious work to reach the 1.5 gigahertz frequency boost with traditional air cooling.

They're basically quoting WCCFTech in this part:

AMD launches Radeon RX 480 with a boost frequency of 1266 megahertz, and according to data Wccftech this shall not be the final goal. Boost frequency of around 1.4 GHz will be fully viable with simple overclocking while with extra excitement and a little more serious work to reach the 1.5 gigahertz frequency boost with traditional air cooling.

Maxwell.

Also, that article:

"Prestandan vid standardfrekvensen 1266 MHz sägs vara nog för att tampas med Geforce GTX 980 samt Radeon R9 390X, även om dessa uppgifter fortfarande är något motsägelsefulla och något redaktionen fortsätter att gräva djupare i."

Translated:

"The performance at the standard frequency of 1266 MHz is said to be enough to contend with the GeForce GTX 980 and Radeon R9 390X, although these data are still somewhat contradictory and somewhat editorial team continues to dig deeper into."

Stock clocks enough to contend against the 390X & 980.

At ~100W gaming load. $199 or $229 for 8GB.

1400mhz OC is easy and simple. 1.5ghz possible with manual OC.

How is that a fail exactly?

You have strange ideas if you think that is a fail.

 

[Silverforce11]

They're basically quoting WCCFTech in this part:

Which both says 1266 -> 1400mhz is simple. 1.5ghz is possible with manual OC, which is what all AMD GPU users who OC are used to.

AMD OC is not as simple as NV, where you bump up the power limit and offset. For AMD OC you need to also bump up the vcore, +25 to +100mV and test for stability yourself. If you OC AMD GPU without upping vcore, more than 10% OC is rare.

It's a more traditional enthusiast way of overclocking.

Another one:

"The performance is at the level of a R9 390X or GTX 980 are, where priced 229 US (8GB) dollars are due. "

I think it's too many times its pointed towards 390X/980 performance to be a coincidence.

Now the interesting thing is how well it overclocks. If it does 20-25%, would make for a beast of a GPU at those prices & power profile. If it's a Pascal-like tame 10%, it will be only an okay deal, very unexciting.

 

[Abwx]

Which both says 1266 -> 1400mhz is simple. 1.5ghz is possible with manual OC, which is what all AMD GPU users who OC are used to.

That s likely, that is, that it s the overclocking at stock voltage, the custom cards will clock better due to higher voltage and surely a more efficient cooling, this also suggest that voltage margin is quite large..

So that s some good news brought by some people here...

reference blower coolers are not cool - I know it's not a high TDP card but I'm expecting lots of noise and high temps under prolonged load anyways, with reduced lifetime of the card as a result

I was hoping I could actually get a decent open air cooler come launch day but nvm

 

[Thala]

If you have numbers to offer for fun speculation based on history and rumours please put forward your guestimates, otherwise there's no room for discourse with you.

That is most likely the problem. You like to discuss based on history and rumours trying to extrapolate facts about future architectures while ignoring facts about how chip design, architecture and technology work.
That's all fine as long as you do not claim that architecture A is behind architecture B based on totally unreasonable metrics or what "real architectural improvements" are. Just stop this FUD.

Keep believing that an AMD engineer finds out after the architecture (e.g. Vega) is done, that it does not fit into a certain die space in order to be competetive on the performance side - all while increasing perf/area is no rocket science as long as you have power to burn.
You should have told them that they have a die size limit before the architecture was done.

No custom stuff, ref. only which in my view is fine as AMD nailed the cooler this time, it looks great, is quiet and performs.

Gibbo is hoping to sell 500+ on day one... seems pretty confident it's a good value.

Whether it's going to entice me to purchase or not depends on the all-important gaming benchmarks (I don't care about synthetics).

I'll believe it when I see it (in actual reviews). I don't think it'll do well even when running w/ stock clocks.

but it might be my irrational hate for blowers, who knows

Blowers are good for low power GPUs. Take for example the GTX 980 and it's blower.

RX 480 is supposed only ~100W gaming load.

 

[maddie]

Stop posting all this wrong info. /s

Here's the absolute truth from HE WHO KNOWS ALL.

Quoted from linked page:

Keeping in mind that HardOCP have not been briefed or sampled on the new RX 480 by AMD as I type this, we have gotten solid information as to supplies on launch day...whenever that is. Expect around 8,000 cards to be available in North America.

Needs page hits so badly? Comments are hilarious. Remind me of a cult following.

I do recall the Fury X launch being hyped to the moon, and we all know how that turned out...

Let's hope this isn't a repeat.
