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

[littleg]

Missing sli 480 faster than 1080:thumbsup:

I have some insider info that's 100%. RX480 won't have SLI :thumbsup:

Thats guaranteed.

 

[Armsdealer]

OK. So give me a single new feature that Polaris brings

For how long HMPs are on the shelves ?

multires shading is supported by Unreal engine since version 4.11 and Unity engine:

Some VRWorks accelerated titles:
Solfar Studios Everest VR
Valve Software The Lab
ILMxLAB Star Wars Trials on Tatooine
InnerVision Games Thunderbird: The Legend Begins
EVE: Valkyrie

and more here:
http://www.geforce.com/hardware/technology/vr/games

Those are just a list of VR games & Steam VR benchmark. Where's Maxwell's Multi-Res Shading being used in games to give it a huge performance advantage? That's the marketing, remember.

Though perhaps if you want to talk about VR tech and stuff in Pascal, make another thread. We are going off-topic.

Too bad ZEN wasn't ready. Instead, AMD uses an Intel 5960x@3 Ghz as a testbed.

The demos at shows were done on Zen machines, or so i read. However, giving people a baseline which they already are familiar with, is possibly a reason why they used Intel hardware.

 

[guskline]

Let's keep things in perspective here. The RX480 4G Vram is $199 and the 8G Vram is @$239. It likely has the performance of the 290/390 if not better and that is incredible considering it's size and cost PLUS it has support for VR and all of the new features.

Comparing it to a GTX 1080, or even a GTX 1070 is unfair.

I think AMD will focus on it's RX 480/470/460 and refine performance from that perspective plus pick up market share.

 

[xpea]

nvm

 

[nkdesistyle]

This WCCFTech 'source' certainly sounds very familiar:

Exact same CPU as the recent asian guy (who faked results), and similar results as well. Core i7-4960X is not a very popular, easy to find CPU.

BTW, about Lisa Su's $100-300's range:

You are assuming way too much there. So same cpu means its fake? Is the the only one in this world with the same cpu? I shake my head when people try too hard to discredit something. Yea it could be fake but common now your reasoning seems as desperate as websites trying to get hits.

That's apart from hardware decoding/ acceleration of x265, with hdmi 2.0b(is it?), DP 1.3/1.4. They're all new to AMD products and at the price point which they're being introduced is also quite nice.

Does anyone have information as to whether AMD's new hardware will be playready 3.0 compliant or not?

Lol Well it was getting late(3am) when i wrote that i will edit it :thumbsup:

About VR, it will all boil down to, who has the best preemption granularity needed to have the best viewing experience.
If brand N doesn't have it, then you will see judder, and if brand A has the best fine grained control, then it would be more fluid to the eye because of async reprojection.

Personally, I still think this generation of VR is just not good enough, and it will simply be for the 1%, with little adoption rate, pretty much like 3D TV was.

 

[Elixer]

I didn't see this posted in this thread...

The graphic card wars are on and AMD hosted an event to show off their latest crimson pixel pushers in form of the RX 470 and 460 models to match their previously announced RX 480. Luckily, the AMD graphics team hooked me up and I was able to get some private time with the new GPUs. No fancy coolers, just the raw goods. At the top of the page is the raw RX 470. Below, the RX 460 with its adorable fan and Crossfire RX 480s.

Now, assuming wccf isn't full of it (a big assumption I know), and 6+8 pin cards are actually justified because certain bins overclock "to the moon" what odds we see a g5x aib? Are they really going to try to con us out of $300 vs $230 just for better fans and a better binned gpu?

You can literally buy your own water block for that price difference...

No, highly unlikely for AMD to do that, though the AIBs still might do it. The 300$ top bin could be the fully unlocked part or just the regular 36CU one with GDDR5x but till the time, the top P10, it's released either of the possibilities make sense from a consumer PoV.

It's beginning to look like AMD could have clocked Polaris way up to like near 1400mhz base and 1600mhz boost to edge near the 1070 but in doing that they would have quickly lost efficiency.

If WCCF is to be believed then 480 reference board uses 100 watts, 50 below the 6 pin max. If there are indeed AIBs thinking about going dual 6 pin or 8 pin + 6 pin with supporting power delivery systems then there's good reason to believe this card may be capable of much more. That would be doubling power draw, and even if the card only gets a 30% boost from that, it will be close to a 1070.

Such a small chip cannot hope to dissipate that kind of thermal output, the size constraints it and I expect 150W is about the max before it falls off a cliff in a thermal rout.

 

[StrangerGuy]

Putting additional power connectors on a card is trivial and IMHO doesn't say anything about the real power draw.

You telling me if its 100w during gaming at 1266, it can't cool around 160-175 with beast of a cooler and little overclock? I have heard these oh it can't happen scenarios. It won't blow up at that much wattage if they can put good enough cooling on it.

 

[BlitzWulf]

Is that really the case though ? Isn't the 270x a 212mm2 die with 180watt TDP?

So you're saying a 30% oc is out of the question? If they slapped on g5x and managed a 30% oc (relatively standard on 980ti) it would almost certainly be faster than 1070...

 

[positivedoppler]

If they can get 290-290X performance for $200 and 100 watts with plenty of OC headroom, this is would be a lethal card and explains why Nvidia rushed out the 1080 and 1070.

But nvm the 480, I wonder what the 470 will be capable of. At $150 some people will buy one just for sng

All rumors so far though, 2 more weeks

I am not afraid to CLC mod. I did a zip-tie CLC on my 7950 Boost for 35%+ OC - it's child's play these days with actual aftermarket mounting brackets.

 

[KompuKare]

Also, if the embargo is lifted on these AMD slides (the fine print says June 13, 11am PST) then why hasn't the deck been posted by any reputable site? I checked Anandtech, nothing. TPU, nothing. Tom's Hardware, nothing. TechReport, nothing.

Well, ComputerBase did publish them:
http://www.computerbase.de/2016-06/amd-radeon-rx-480-vr-benchmark/
But the benchmark slides seem to be missing.
Also, WccfTech leaked some performance numbers:
http://wccftech.com/amd-rx-480-faster-than-nano-980/
3DMark Firestrike Ultra again, but they say actual gaming performance is better than the 3DMark.
More interesting are the snippets about AIB cards and so on. Typical gaming draw of reference is meant to be 100W so it seems AMD are keen get good perf/w and will leave overclocking to AIB models.
Anyway, leaks are all over the place, so best to wait for actual reviews.
And again, if the RX480 does well in Ethereum mining there may be crazy mining demand again. Maybe AMD well deliberately limit is mining performance in the drivers?

Nice picture. Let's have some fun measuring P10 with Photoshop's vanishing point:


If we use the PCIe connector as the reference measurement (85mm)





Board length: 180mm
Package: 40.3mm side, we can probably round this to 40mm*40mm
GPU: 14.3mm*18.38mm = 262.83mm²

Using the package's 40mm side measurement as reference, we get around 257mm² as die size.



Bigger than the rumored 232mm²? Seems so. I still adhere to the theory that RX480 is using a cut down P10 and this is probably a 40-44CU chip. Apple is probably the customer for the full dies, as happened for most of Tonga's life. AMD is probably putting every die they get out of GF to good use, making the most out of that WSA around their neck.


AMD did give us this the first time they unveiled Tonga:

1792sp and 256 bit memory bus, yeah right. Tonga has 2048sp and a 384 bit memory bus in there.

Therefore, no reason to take this as final P10 hardware specs, but P10 specs at this point in time. AMD wants to take the mainstream market and they need volume. You get volume on a foundry known to screw things up, on a new node, by cutting your chip down until they get the hang of fabbing it.

There's something above the $230 8GB RX 480 in the future that's probably P10 based and I don't think it'll only be 6+6/6+8pin overclocked cards taking advantage of the 28->14nm clockspeed increase, more like the R9 380x we got in the end after Apple was done with the full Tonga dies. Vega chips are well into 2017, AMD probably isn't going to rely only on RX480 to get there, but spice things up by aiming a little higher than the mainstream if not only through clockspeeds.

I don't expect anything more out of stock, confirmed 36CU RX 480 than 390-390x performance at $200-230 which is an excellent deal already and outside of the US alone it'll probably be a great success (here in Argentina it'll sell like hotcakes, computer hardware is expensive and this is a very needed breath of fresh air), but come on, there's reason to think there's something more going on than the RX460/470/480 we know so far, apart from the leaked slides.

Just two more weeks until June 29...

So it looks like the graphs are from AMD.

What I said earlier was right. The 14nm and new architecture benefits are moved entirely to lower prices. And the price alone makes up for what's a middling product, in VR, in gaming, in general.

But as a technological advancement its mediocre. It's a 390X shrink to 14nm. It doesn't looks like it has VR specific enhancements like Nvidia had for Pascal.

What hoopla both companies make for die-shrinked chips!

Post-Vega for AMD and Volta for Nvidia is what true next generation architecture GPUs are. Of course, looking at what these "ground breaking" FinFET/TriGate transistors brought for Intel, it's going to look like Haswell. Ok, but not breathtaking as promised.

The new slide says 36 CU, but this time it's under Polaris 10 and not just RX 480. So this is it. It is possible GCN 4 CUs use significantly more transistors, and also, they made the design less dense for better efficiency.
