AMD Polaris architecture – GCN 4.0

360x120mm cooler for single GPU. They must be overclockers dreams for it to be that big

no it's for dual gpu card, although this must be something for Q4 at best not right now

I hope it is true as well but im not getting my hopes up

I suspect the videocardz leaked benches are probably closer to the truth as they were bang on with the 1080 and 1070.

The videocard benchmarks fit all the rumours and spwculation. The numbers are exactly where you would expect them to be given AMD stated efficiency improvements, the node change, previous architectures, stated power consumption, leaked shader counts and Clocks speeds, CEO.statements.

For big polaris to seriously contend with the 1070 then many of the rumours and leaks would have to be wrong, and AMD would have had to have lied about powr, size, market segment etc.

It's of course possible but then the rumoured price points will be wrong as well.

Polaris looks like a great GPU but I think it's very damaging to ok AMD to hype it up to something that by all accounts it is not intended to be.

I would assume it's foe a radeon pro duo, nothing to do with Polaris.

I think we'll see a baby Vega take the 490 series moniker and big Vega get its own flagship naming ala Fury.

As for Vega and 4k, well I'd say that to get the same performance that P10 would get at 1440p, but in 4k, Vega would likely need to be about 100% more powerful(in actual demonstration, not just on-paper flops or whatever). Most benches show that framerates are halved going from 1440p->4k.

I'd say we're still a generation away from 4k/60fps being a truly reasonable target to attain from a single card solution.

Tbh they could conceivably make endgame Vega 2.5+x the rumored size of p10.
Also it providing AMD slides are not straight up lies. Vega is a generation ahead in efficiency than polaris.

Ofc that's not to say endgame Vega will be anywhere near 3x as fast as p10, but it should not be impossible to have a 4k capable card. Just a matter of how far off endgame Vega is (I'm guessing a year).

Also assuming AMDs slides aren't lies or misleading (which I'm still confused about/skeptical of) even any good size Vega should be beastly.

I dunno, the GTX1080 is getting mighty close to 4k. I was kind of thinking that the 1080Ti might do it. And big Vega too.

Sure I could happily game at 1440p for a few years but I am desperate to go full blown 4K. I want the monitor to watch 4K youtube and amazon anyway but it would be a crime not to game on it at 4k. Don't want any blurriness when downscaling to 1440p. Argh I dunno. Its a headache.

I'm probably going to wait on 4k myself instead of jumping to 1440p(cuz 4k plays nicer with 1080p content which I still have with movies/consoles/etc).

GTX1080 is getting close in some games, but for me, 'some games' wont be good enough. I want a card that can do *anything* at 4k/60fps with at least High settings. Maybe big Pascal/Vega will do it, but I'm not counting on it. Not after seeing 4k performance overall for the 1080.

Vega is a generation ahead in efficiency than polaris.

From my understanding, it's going to see some improvements over Polaris, but it wont represent a full generational architectural shift.

Cheers Greg, genuinely appreciated from someone who doesn't spend the time trawling through the thread looking for the occasional glittering nugget.

Roll on more info/samples/reviews when they turn up.

I was holding off buying a new 1440p 144hz monitor but I have a feeling I may have to go for a 4k monitor instead soon, how far are we from 120hz 4k panels?

If we're close now to 4k single gpu, I can imagine come Vega it should be a reality, therefore xfire and a 120hz panel might be a possibility

Reported? Holy hell, we're in Kindergarten here.

Unfortunately it's like that here. A few here like to cause trouble. I'm to old to play these games. Just ignore them mate.

Apparent leaked slide, The figures put this at 980TI - Titan X if it is real.

Not to be mean, but isnt most of what he posted wrong or completely unfounded?

ie the price, bus width , name etc . I havent seen any leaks or rumours stating the price, 512bit bus or that it wi be the 490/490x.

 

[humbug]

Apparent leaked slide, The figures put this at 980TI - Titan X if it is real.

How so?

The slide is comparing it to a GTX 970/80.

+1 i am tired of 1080p too, and dont want 1440p(usualy i just vsr for it), and waiting for 4k starting to look like an eternity, a year ago i had a delusion that late 2016/early 2017 would be 4k@120 HDR monitors with cards driving a 60-80fps.
but reality is not as pretty... 4k@120 are like 3k$, no HDR, and GPUs are nowhere near that performance.

How so?

The slide is comparing it to a GTX 970/80.

I think in the sense that if the 480 is matching or beating the 980, the 480X should match the 980Ti. That's me being hopeful though.

We just need to be a bit more patient, not long now until Computex.

 

[Mauller]

How so?

The slide is comparing it to a GTX 970/80.

The performance metric, the 970 and 980 have theroetical performance lower than 5Tflops.

 

[AlamoX]

comparing it to the segment it competes with, makes sense

 

[humbug]

The performance metric, the 970 and 980 have theroetical performance lower than 5Tflops.

The 390x is 5.9 TFlops.

Its bottlenecked by its instruction scheduler so maybe if AMD managed to sort that out.

Well GCN4 does bring a lot of improvements to the shaders and command processor, improving single threading in the command processor and shader utilisation through instruction pre-fetching etc.

So i expect Polaris parts to perform far closer if not at their Theoretical performance compared to GCN1-3 parts.

 

[CAT-THE-FIFTH]

How so?

The slide is comparing it to a GTX 970/80.

The TFLOPS figure is more like an R9 290X. However the slide could mean one of two things:
1.)GTX970 performance at a much lower price point
2.)It is priced at around GTX970 level and hence it is the main competitor to the RX 480

i think thats the 480X, the new name RX 480 could be for the XT version, maybe the cutdown will be RX 470, and polaris 11 RX450/460, AMD had way too many card anyway.
but what's with that 6pin! not even an 8pin ?

 

[Jono8]

Apparent leaked slide, The figures put this at 980TI - Titan X if it is real.

How so? That is less flops than the 390x. That says to me that it is going to be around 390x performance especially as it is being compared to the 970 and 980.
