RX 490 Rumors: What do you think it will be?

[therealnickdanger]

Speculate you say?

R9 RX490 will be a $299, water-cooled, mini PCB model like the Nano. Super binned, under-volted 1600MHz unit.

 

[crazzy.heartz]

People need a $400 Freesync GTX 1070 alternative..

One 4GB 480 costs $199
2 480's with 8GB on a single PCB(cost savings) is easily feasible for $400

Launch this GPU for $400 and when NVidia starts selling its 1070 for $389, discount the price to $375; or even leave it b as there is demand for a $350-$400 1070 exivalent GCN 4 AMD Freesync GPU.. which 2 480's are...

Crossfire on a stick

 

[crisium]

Oh, I forgot I need to speculate to my heart's content.

Rebadged Fiji, since with undervolting (Sapphire Fury) and binning (Nano) it can match Polaris performance-per-watt anyway. Some kind of magic will let them sell it below 1070 MSRP and still make a profit.

Too bad there's no 8GB HBM1 magic. Or is there...

 

[zinfamous]

490 = either small Vega or the dual Polaris 10.

I think 485 = 480 w/ DDR5x

 

[Midwayman]

I think its a little early for a dual polaris. Maybe once dx12 is more estabished.

Best bet is probably small vega. 490 will probably be the cut down part while they build inventory of full chips for the fury replacement.

 

[gamervivek]

Would dual GPU have derived model?

Not sure but the second digit identifies the chip used and the third is the config. it's used(fury x, nano or fury x2), that has been true for Hawaii and Fiji based cards.

It could be that C99x is dual Polaris 10 but I find that very unlikely. The Dxxx PCBs of current 480 are less than half of C99x prices and the other C954xx board is closer to RX480's price.

Fiji w/ HBM2 and they discontinue the Fury name priced at $350.

 

[ZGR]

512 bit bus, 8gb gddr5x, faster than gtx 1080 @ $500. I wish.

 

[NostaSeronx]

RX 490 8 GB GDDR5? Nope, it is just Vega 10.

4352 ALUs : 272 TMUs : 64 ROPs : 1.4 GHz GPU
2048-bit Phy : 8 GB HBM2 : <2 GHz Memory
~275W TDP : ~412 mm²
P-Launch -> September 22nd, 2016 : $549 (Base)

There will be Vega 10. 64 CU, 8 GB or 16 GB HBM2. It will almost certainly be faster than GTX 1080. But won't be released till early 2017.

 

[garagisti]

since when has a x90 card been a dual gpu card?

I'd be slightly more inclined to believe vega 10 over dual polaris.

6990, 7990?

 

[garagisti]

It's either:

1. Simple dual 480x2 with 2*8pin connectors, 8GB

(Not sure AMD would want to spend RnD time/$$ to include GDDR5X or HBM or higher 384/512 bit bus on a limited run/requirement card to hold on till Vega arrives..

2. Small Vega with all its GCN 5 goodies.. Most likely with GDDR5/X

Or (Highly unlikely)

2 480 chips connected together like a dual-core processor which presents itself as one big GPU to the OS.. (read somewhere on Videocardz/wccftecj.com)

Now, THIS would b AWesome !!

As crazy as it may sound, AMD may want to experiment with dual chip on interposer before the next gen. I think you may be right in that it could be 2 binned Polaris 480 on an interposer. I was going to say highly/ specially binned, but AMD's been letting voltage slip too high on for multiple generation of chips now, so binning AMD's chips for such a card can't be that labour/ time intensive.

That's highly specific for speculation

Ooh, if made on 14nm that would shame a few new gen cards possibly in both DX11 & DX12

I had read that it takes a different bump layout (sorry I'm not technically inclined enough to know what the difference is) to work on an interposer. They can't simply slap a Polaris 10 on an interposer.

 

[geoxile]

I don't think a dual GPU card at this price point would sell very well, at least not enough to fill the role of a $300 to $400 card.

I had forgotten about that.

Well, it may give AMD pause to drop voltages and make Polaris totally respectable, even by their detractors that said, i doubt AMD would do themselves the huge favour. However, it seems quite possible an alternative, as they'd possibly want to try it out before they move to Navi.

Absolutely. They've flat out raised voltage across the board so that all chips meet the required launch clock targets; whether they required it or not. It appears most didn't; as per reviews.

Also, AMD would have to design chips with dual-chip config in mind from the very beginning. Is there a way to verify if 480 has those bumps, as 3DVagabond mentioned !?

If so, july-dec months present them the perfect opportunity to test this feature with 480's as they routinely slap together CPU & GPU's to make APU's for XB1/PS4..

I dont have much knowledge abt this process so don't know ;-]

Again, AMD never shy away from experimenting so who knows.. they co-developed HBM & successfully implemented the same.. Before anyone else..

 

[railven]

I recall there being rumors of AMD working with both GloFlo and TSMC.

So, perhaps, 490 is Polaris 10 on TSMC

Unlikely. P10 is for mass market, mainstream which targets lowest cost possible. Designing/porting it to 16 nm, would cost a lot more money.

Which is completely stupid if you consider what market it is aimed at.

At the roadmap the "dot" that symbols when particular architecture should launch is still in 2016, however with very small percent.

Look at Siggraph conference. Maybe there we will see a little more, considering that HBM2 will have ECC memory mode, and it will be viable to use it in HPC market.
