Reference-Design Radeon HD 7990 No Longer a Unicorn

In its GDC press-briefing on Tuesday, AMD previewed the reference-design Radeon HD 7990 dual-GPU graphics card. The company dragged its feet over such a product throughout 2012, and allowed its AIB partners to launch graphics cards with their own designs. Among the two that made it to the market were a PCS+ board by TUL, sold under the PowerColor, VTX3D, and Club3D brands, and the ASUS ROG ARES II. While those cards had different company codename, "New Zealand," the new HD 7990 is being referred to internally, as "Malta."

AMD's belated move to launch the Radeon HD 7990 reference design could reiterate the company's long-haul strategy with the Radeon HD 7000 series, which could sail the company through the crucial Summer sales season, over to Q4 2013, when the company is expected to launch its next GPU generation. AMD's reference design HD 7990 enjoys an edge over current market offerings: dual-slot thickness. It uses three 90 mm fans to cool a complex heatsink cooling the two GPUs, the bridge chip, and the VRM to feed them all. AMD didn't speak much about the card, but mentioned that its triple-fan approach is paying dividends. "It's whisper quiet," commented Matt Skynner, general manager of AMD's graphics business unit.

from the looks of it I will need a full tower to house that baby and then maybe hacksaw too.
I guess 30-33 cm. Looks like 30cm to me, given the distance between PCIe plug and output vs the other side of the card.

Could be a "new" chip, but even if it was, it wouldn't matter. Binning can easily give 1100MHz GPUs @ <175W.

Looks to me like they might have managed to give it the powertune features of the just released 7790.

It would explain the higher clocks combined with the apparent lower poweruse.

If these were a bit cheaper like $699 I think they would be much more interesting.

Shush. I have 2x7970 and a 7950. 400W is minor, really. I bloody well want this card.

But, I want many things.
That shush got a good chuckle out of me.

Yeah i really want 400w of heat expelled inside my case
That's kind of fortunate given the TDP of your main rig.

They sure wanted to make EVERYTHING look as shiny as humanly possible. Even things that shouldnt be shiny.

A drop of water or Extreme high voltage at lowest possible for both GPU will do amazing job. :D

to me, the only positive aspect that this card might bring is forcing nvidia to lower the prices of titan and gtx 690 altough that seems unlikely. otherwise who would want that stuttering and that awful frame latency? good thing that AMD are adressing this major fault, one game at a time LOL

I would hedge a guess and say this will be released when latency issues are fixed/half fixed, so they can advertise how wonderful their crossfire dual chip card works without high frame latency.

Malta chip == cross between Tahiti XT and Tahiti LE. 256-bit memory bus width and package size of Tahiti LE, but the stream processor count of Tahiti XT (2048). Source: my magic arse.

That would actually make a lot of sense, except such a chip wouldn't draw 200W each unless @ 1200 MHz or higher. I guess that would account for AMD's claim to "higher performance" than current dual TahitiXT2 cards.


Oh, and I need to retract my comment about size of the card. Looks to be near 40cm, or 16 inches. I say 15 inches, there's a lot of card past where the power plugs are.

Same reference design as the FirePro S10000

The FirePro S10000 PDF spec sheet just says
]Full height / full length form factor

Take out your measuring stick



I'm with btarunr magic arse. It has to be a new chip or else its just extremely late. I'm thinking more of the lines of a Pitcairn XT or Tahiti Pro succesor with Bonaire improvements. Bonaire with 6 watt TDP increase along with die-size and they were able to pack a good chunk of performance in there compared to Cape Verde XT.

Since we know the exact length of the PCIE connection. We have the pic of the card. Find the ratio of card length to that PCIE connection and multiply. You should be within .5 in with this method.

Since Most FirePro/GL/Streams are from the same silicon as their Radeon parts with a bios change and major software tweaks for the Fire series.

well both my 4870x2's together are really starting to show just how long in the tooth they really are and this is appealing for sure :toast: I am sure I will only be able to afford one but still a foot in the right direction.:o

Looks like AMD is being really smart here by using 3 big fans as opposed to a blower design, bigger fans = more air flow at lower RPMs, this should keep thermals and acoustics in check, this should be a monster of a card.

The only issue is blowing this heat into the case as mentioned by others, but if your case has a good airflow (and it should) this shouldn't even be a problem :toast:

for it to be a dual slot cooler unit which looks like something from arctic cooling
