AMD Fiji XT Reference PCB as Short as GTX 970 Reference, R9 295X2 Performance

[btarunr]

AMD's upcoming Radeon R9 390X graphics cards will ship in two SKUs - an air-cooled one, with a moderately long reference design board (though not as long as the R9 290X), and a new Water-Cooled Edition (WCE) SKU, which will feature a very compact PCB - one that could be no bigger than that of the GeForce GTX 970 reference. This is possible because of AMD's HBM implementation. The 8 GB of memory on this card is present on the GPU package, as bare 3D-stacked DRAM dies, surrounding the GPU die, with an IHS covering everything; rather than the GPU package being surrounded by memory chips. Below is a mock-up of the card by ChipHell. It's not a picture. The radiator is off-proportions, the Radeon logo is misaligned, and the PCIe I/O is misaligned, etc. It should still give you a good idea of what the card looks like, particularly its length. Other specs on hand so far, include 4,096 GCN 1.2 stream processors, 256 TMUs, 128 ROPs, and a 4096-bit wide HBM interface, which at 1.25 GHz memory clock, will offer memory bandwidth of 640 GB/s.

While Fiji package will be bigger than that of, say, "Hawaii," overall the setup is more space-efficient, and conserves PCB real-estate. The PCB hence only has the GPU package and the VRM. AMD is doing away with the DVI connector on its reference PCB. It will only feature three DisplayPort 1.2a and one HDMI 2.0a. The WCE variant will feature a pump+block covering the GPU package, which will come factory-fitted to a 120 x 120 mm radiator. The air-cooled R9 390X will be longer, but only to house a heatsink and lateral blower. The single-GPU card could offer performance comparable to the dual-GPU R9 295X2, which is faster than the GeForce GTX TITAN-X. AMD CEO Lisa Su, speaking at the Investor Day event, in New York, on 6th May, hinted that the product could launch on the sidelines of either Computex 2015 (early-June) or E3 (mid-June).

Not long to wait. I'll not cling to any hope of the WCCFTech claims about performance but if it is, well, that's pretty awesome. Next new card for me.
It'll be weird though (with HBM) having memory on chip and smaller cards with more power.
No more behemoths. Almost a sad day for open cases!

Just shut up and give us R9-390!

I'm drowning in the huge amounts of salt i have to take with all the AMD fuzz lately.
Truckloads of salt.

I prefer it. I dislike using cases when possible, and prefer smaller motherboards when I can use them. This just means it takes up less space on my desk/shelf or other area I have placed the computer.

I don't know if the smaller PCB size means that much when you now have to have the space for a 120mm radiator in the case.

 

[Breit]

I wonder if there will be a single slot bracket in the retail boxes? Looks like single slot cards are possible again with a proper aftermarket water cooler.

Lets us all hold hands together (yea - also all GreenTeam fans too - cuz if this Red product will be true - then Green products will receive a hefty price cuts immediately).... and hope this will be 100% true

I just hope AMD is allowing their premium partners to launch cards with aftermarket aircooling from day 1 to avoid the disaster of R9 290X reference.

Oohhh the irony... You, sir, made me giggle and laugh. Take this thank-button.

Hope the PCB is short enough so that it fits my Lian-Li TU100 perfectly.

I think we just got hit by a fkn meteor of salt. An A-10 raining down a good BBBBRRRRRRRRRT of pure salt crystals.

But it whould be awsome if half of the claim was true, my current 3.5gb card needs replacement to handle higher resolutions, and it needs to fit in my itx case.

Hey buddy, save that for your Ku Klux Klan meeting please. This isn't an appropriate place for it.

edit: I removed the racist word he was using from his quote in my post.

 

[Octopuss]

So this will stil be 28nm?

 

[Mysteoa]

It will only feature three DisplayPort 1.2a and one HDMI 2.0a.

Shouldn't that be DisplayPort 1.4a

That's one helluva lot of salt you have there. Careful, so much salt is bad for your health.

You'll need a custom waterblock to begin with, because those HBM chips are likely to end up a good bit taller than the GPU die itself. I think the single slot bracket is going to be the least of your worries.

Since it's the most advanced manufacturing process currently available for GPUs of similar size, yes, it's still going to be built on 28nm.

 

[Breit]

No. DP 1.4a is for 8K displays, but DP 1.3 was expected at least. I mean 5K displays are already here.

The GPU die including the HBM modules are under a common IHS, so I expect a flat surface on that IHS. But anyways, there will be waterblocks nevertheless. Trust me.

When we are all disappointed by AMD bulldozer v2.0, hitler will be screaming at his lieutenants again

Why have you removed WCCftech's logo from the image?? This is not part of the common license agreement
Although you cite them that is illegal so I suggest you place the original image on you article immediately as I am ready to take this one step further

Or they sent him the original. He probably didn't remove the watermark by himself.

Is the image property of WCCFtech? Was it produced by WCCFtech or acquired through a leaked source. Is it from AMD's presentation? You can't own an image that isn't yours, even if you slap a logo on it.

Incredible

WCCftech clearly states what information is speculation with a *. You should read that if you want to know whats real or not

The fact this site took an image and doctored it is discusting.
Using an image is one thing, and legal. Doctoring other peoples property is no and is illegal.

WCCftech are the most honest site around who sound out rumours when they are.
They do not hold favouritism either which is why they got the image in the first place.

You need to understand that

The image was given to them. NOT THIS SITE.
using images is one thing if cited. Doctoring it is illegal without authorisation.

Yes it is the property of wccftech as it was given to them.
