AMD publishes Polaris Architecture microsite

[kalniel]

Interesting to see the Ebuyer email this morning containing some AMD graphics cards. Could this be the start of the stock clearout before the new cards come in?
£120 off a Sapphire Nano: http://www.ebuyer.com/722460-sapphir...d-21249-00-40g

That's a bit sneaky of ebuyer - AMD droped the nano price back at the start of the year so it's nothing like a £120 off.

Personally, I think Vulkan on Windows will be near non-existent. Most "low level API" titles on PC will be XBone ports on DX12.....quick and dirty

If you are going to be that lazy as a developer, then isn't that the point of using an off the shelf game engine like Unreal or Unity? That sort of sets your supported APIs for you.

Last I looked the price had gone up again. OK it was never going to happen, but as I was forced to buy a card and was looking at the 380 I was going to check out 390 and nano prices as well

Ellesmere XT still belongs to A0 chip testing phase frequency? Stream processing units ? Sorry, now measured in simple terms is that these are now filled with now is a transistor chip, as it is to edit the number of stream processors with much frequency much power run ah, now just do this thing, global workforce in RTG under the collaboration, we expect the third week of may to provide A1 official version of the chip for testing at that time, performance, power, basic specifications can be determined, and the rest is driven adjustment and optimization of the product before the A1 chip out, any run points are guessing right, RTG has now issued a PCB design reference suggests, the various AIB has entered card pre-production stage, relatively speaking, Baffin PCB's proposal is very short and simple, 4-layer PCB + single fan on can, but also shorter than the Nano
Ellesmere's PCB recommendations are slightly longer than the Nano, but as long as the 6-layer PCB + single landlord asked AIB fan who can not engage in gas stove, AIB say can consider engage cooker ...
AIB landlord asked who can not engage in a three-fan, AIB say we going to put two fans when the display it ...
Finally Ellesmere Pro now with Baffin A0 are not out, do not rush it, RTG efforts in the
PS. Which help me to take a message to the USG Ishimura, to see if he says the 1070 have been suspended or beaten 980Ti, Polaris represents less people first

So,Polaris 11 reference cards are shorter than an R9 Nano and the Polaris 10 reference cards are slightly longer than an R9 Nano.

Also says cards have entered pre-production at AIB partners.

That actually requires the devs who PORT the code from XBone to make the necessary changes......what evidence is there to show they will actually do it? There is plenty of evidence around at the moment to the contrary....look at the dev comments from the QB team "Too hard to implement". I am sure it isn't "too hard", I just read it as "PC versions sells too little to bother spending the time trying to implement it".....now unless PC titles start selling 5-10x more, that isn't going to change.

Mantle work? What has that got to do with current and future DX12 and Vulkan titles supporting mGPUs? Personally, I think Vulkan on Windows will be near non-existent. Most "low level API" titles on PC will be XBone ports on DX12.....quick and dirty

Mantle, Vulkan and DX12 all come with the promise of greatly improved multi GPU scaling. That was part of the big sell. Mantle's development lead to Vulkan and DX12. AMD handed over the code and most of the dev's from Mantle are now also part of the Khronos group.

Annoyingly that means I'll now be able to buy a card as a decent price that would allow me to re-install my optical drive.....now that I have stopped using physical media :S

I'm more than happy - last card I installed (960) caused much grief with its length.

I mini-ITX case has no optical drive,so have to use an external now!!

I have this GTX960:

It is tiny!!

[Xlucine]

Huh, it's smaller than my 750ti

So Polaris 10 should offer a (R9 480?) Nano sized card and offer performance better than a 390X for around £200, if we believe the details floating about.

So Polaris 10 should offer a (R9 480?) Nano sized card and offer performance better than a 390X for around £200, if we believe the details floating about.

Or more realistically slightly longer than Nano, performance between a 390 and 390X and £250 if we believe the details floating about.

I was having a think about it - a 232mm2 14NM chip should have more transistors than Hawaii and that had significant DP performance,which I doubt P10 will have. So only matching an R9 390 or R9 390X seems a bit lack-luster in some ways. I would expect it to be faster and consume less power.

After all the HD7870 was 10% faster than an HD6970 and consumed 80% less power.

How much larger would the card have to be than the Nano to be realistic in your opinion. Slightly is a little vague.

Possibly (certainly way less power), though I have in my mind the Fury/390X comparison - do you think we'll have more stream processors in Polaris 10 than Fury? I suspect we'll have fewer, and given Fury is perhaps 20% faster than hawaii even with HBM it's going to depend on quite a clockspeed boost to pull back the deficit IMHO - which again I hope we'll see, but being pragmatic I'm not sure we will.

Vagueness in a forward prediction with virtually nothing to go on? Surely not! I think we'll see a range of card sizes, but I don't think the reference card will be as small as Nano because of the GDDR5 packaging constraints. I think it'll be more in line with the small 960/970s we started to see recently.

[jigger]

Looking at the clockspeeds 16nm is hitting frequency could be a huge factor for AMD's 14nm chips.

Looks like AMD is doing something at the end of the month:

Hmmm, possibly trying to preempt the 1070 release, if we read their comment about targetting mainstream as meaning the 1070 area. Hard to say since they werent specific, but would be good timing to get in just before the 1070.

Interesting they're still saying up to 2x performance per watt improvement though, since Nvidia are saying 3x and they were already more power efficient, and AMD is on 14nm vs Nvidia 16nm. Unless they mean it additively ofcourse.

Edit: Hmmm further into the article theres this

According to AMD, the Radeon R9 Fury series cards are enthusiast grade products. Everything below them that includes the Radeon R9 390 and Radeon R9 380 series are mainstream cards.

That could well mean a 490 release to compete with the 1070, releasing around the same time hopefully.
