the same cooler as 300series ? come on ...

?????

The 300 series only had custom designs, no reference ones. Not sure what your smoking, or maybe just trolling I guess.

There was some reference designs on stage at that fury event with a blower style cooler (same as the one in the pics) but they never seemed to make it to market, just third party ones.

All that money spent on GPUs nothing left for a proper bed

To sum up what we know about Polaris for those who might have missed it among the dx12 discussions....

It will be called a 490 or 490X, so we assume it will be the 390/X replacement.
It will compete with the Nano
Clocks are not stated or overclocking potential.
Memory isn't stated but I expect 8GB of 512 bit as standard.
Price is expected to be low, so expect $350 ish

Vega potentially coming pre Chrimbo but could be as early as October and will be the big card that is expected to give a 1080 a beating and should be competing with the 1080Ti.

Considering the Doom leak, and the new leaked slide, isn't polaris going to be called RX 480?

nVidia went beyond just the GPU level with their DX11 performance - they are actually modifying certain DX functions before they even hit the drivers proper.

+ Better Delta compression and Tessellation culling.

AMD have brought in thier own DX11 and Driver Hacks, which is why Hawaii has gained so much overall performance compared with the 780TI.

But those things on their own are not enough.

Delta colour compression is an improvement AMD have already brought in with GCN 1.2, in a couple of games where this really matters a 380X is a match for a 290X, i did have some slides somewhere to illustrate this when the 285 was released.

What remains is that improved scheduler and Tessellation culling, both of which should be in GCN 4.0, if we do know a couple of things it is that which we know.

But the Polaris parts are using an improved architecture which more than likely gets far closer to its theoretical max. You can't expect the ingame performance to theoretical flops to be the same, it should in theory be higher for the polaris parts.

'More than likely'? Sorry man, I dont work off of optimistic thinking.

And it's not that I'm cynical. Not at all. I'm just cautious/skeptical. AMD's last couple actual new product launches(Fury, 385) have not met with the positivity surrounding them beforehand.

Also, spell check on this is telling me I'm spelling 'positivity' wrong. Am I? WTF? lol Got me checking the dictionary here in case I'm just having a brainfart.

Also, 'brainfart' is not in the dictionary.

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

Did you read the article? It specifically said for a single gpu

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

There were two coolers shown there, one was for a single gpu

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.

Exactly my thoughts. It was too funny when the guy posted +1 haha. The saying the blind leading the blind came to mind

For me its increasingly starting to look like AMD have brought all the necessary improvements to the architecture BUT P10 will be a small 380X like GPU no faster than a 'DX11' 390X.

Davanius · 31 May 2016 at 17:45

As a 390 owner, what will AMD bring for me this summer?

Considering that slide only shows it using a single 6-pin for power I hope it's at least very cool and quiet as well if it only matches that performance.

The 1080 shows what can be done on a single 8-pin power connector, I hope the 480X, and 490/X bring the necessary jump in performance AMD needs to not only capture the mainstream but also gain ground in the Enthusiast area.

If as people keep saying "cheaper more power efficient 390X" is true the answer to your question and mine is:

#### all.

SiDeards73 · 31 May 2016 at 17:47

That 480 leak states the price will be $199 - $250 USD, so dirt cheap really

After VAT and all thats £190 to £240, if its a "more power efficient 390X" its not cheap.

Its a generational up step from the 380 which starts at £160.

If the card is around r9 390x level and AMD has made improvements to DX11 performance it might be able to pip the GTX980 IMHO. If you look at the TPU review the R9 390X is around GTX980 level:

http://tpucdn.com/reviews/NVIDIA/GeForce_GTX_1080/images/perfrel_2560_1440.png

That would make the GTX1070 25% faster.

If we assume the GTX1070 to be Titan X level,and the cheapest aftermarket ones are £320 to £350,AMD would have to price it at £250 to £260 to have similar price/ performance to a GTX1070 and I think the latter is not the greatest price/performance increase we seen.

AMD would have to get closer to £200 to £225 to be better price/performance and also it would have a £100 gap for safety too.

at this point i dont expect any surprises from polaris reveal, i think it will be what everyone thought for months, best case nano/fury pro, worst case 390X, so it should be right in the middle of this and the gap is very small anyway it's like 15%.
all comes down to the price, it's super critical for polaris, AMD have to make it compelling enough for ppl to skip the 1070 and settle for the 480

SiDeards73 · 31 May 2016 at 17:52

Hmm yeah it needs to be sub £200 really I think to warrant it selling in droves.

Cut down P10 at $200-250 makes sense.

And I think we really need to step back and see that this isn't 'dirt cheap' by most people's standards. We're on a hardware enthusiast forum where 1440p monitor owners rival 1080p monitor owners! Not representative whatsoever of the 'average' PC gamer.

That said, depending on what the performance is, it could totally bring 1080/60fps/High-Ultra to a pretty huge number of PC gamers. Most people do not have 970/390-level equipment.
