AMD "Hawaii" Based Dual-GPU Graphics Card Around the Corner?

[HumanSmoke]

i can see 8gb per core for 16gb total casecutter.

Well, if I were AMD I'd go for broke too. May as well max out performance to offset the inevitable downsides- because if history has taught us anything about AMD product launches, and duallies I particular, a couple of things are certain
1. The card will launch with half baked beta drivers
2. It will launch in the same timeframe as a AAA gaming title that has no CrossfireX profile.

...and sure as sh*t, a dual GK 110 (GTX 790?) arrives in the same time frame to make the "worlds fastest card" argument another debatable topic.

2x AMD R290x is desirable because it would reduce the occupancy of slots . Hopefully that will stand up to current building 2 GPU units, and will cover only one slot to upgrade the copper block for liquid cooling . Consumption is high but so far this has never forced cutting the full power of both GPU and I do not believe that it will descend so low as INVIDIA in this area ! Because of me, you can have the use of a 600W in a stronger bios setup or more . AMD 7990 may doo no problem to 1200Hz clock if only the well- cooled and power supply is sufficient . Here is the best option to give a slap INVIDIA and sell cheap strongest card as it has already done before.Not to mention the potential if the card took only one slot and a multi GPU can reach max 20 units on one board ! 20! not 4 max! We must not forget that AMD has changed its CrosFire , thus limiting the number of GPU units on the number of slots that can be associated with the CPU or PLX . 2 x Xsenon (80)and 10 slot board 20 GPU on x8 max but we know that it works well on x4 too . Realistically could each have at least 8 GPUs attached to one PC ! LOWE to get it.

For what is the prerequisite PCB size, two big die’s eat some real estate. It doesn’t leave a lot available for memory, unless they can go with dual stacked GDDR as AMD has been working on HBM 3D Memory standard.

I was under the impression there was no reference board for the 7990 which is why there was no official amd drivers at first. Once amd came out with drivers the cards were much better the powercooler cards were nice but they never got their in house drivers working right. This would be the first dual gpu reference board since the 6990 if im not mistaken I could be wrong. with the right water block psu I like dual gpu cards for small form factor setups it will be interesting to see the final specs maybe 16gb ram

This is the 7990 reference design.

AMD - AMD Radeon™ HD 7990 Graphics Card

AMD has used the cooler in there FirePro series.

They already have an improved Heatsink with the one they used in the Sky 900

4x6 +4x8 design

Most of the pitch-fork cooler use that combo now. They could do 6+10 as Asus does but with a better Heatsink design.
4x8mm for each core would be ideal.

The 7990 also had 90mm fans running up to 4k rpm. Improving the fans to 92-95mm and a 2.0mm H2O its can stay under the designed 95c and still be quiet without needing to spin pass 2500rpm.

Is it possible yes. Will they do it probably not.

AMD Radeon R9 295X2 to feature hybrid cooling solution

ueweenPC has some exclusive, confidential information about the upcoming Radeon R9 295X2.

According to their story, AMD has showcased the reference model of R9 295X2 behind the closed doors at CeBIT. Only few people had the opportunity to see it.

Dual-Hawaii is called AMD Radeon R9 295X2
The site claims that the official name is Radeon R9 295X2, not R9 290X2 as we previously believed. AMD already has few entry-level cards with a similar 2×5 naming nomenclature, so it is not very surprising. Speaking of 295, the codename does remind us about GeForce GTX 295, which was also a dual-GPU card.

AMD Radeon R9 295X2 is clocked at 1GHz
Official slides, which were shown to the editor of Bouweenpc supposedly confirm the clock speed of R9 295X2. Of course this also brings a lot of speculation whether R9 295X2 is even a full fledged Hawaii-based card or, for instance, it features 2560 SP versions.

AMD Radeon R9 295X2 has a hybrid cooler
AMD Radeon R9 295X2 would arrive with a hybrid cooling solution. The cooler would be equipped with an external 120mm fan, something similar to ASUS ARES II cooler (as shown below). Apparently two AMD partners confirmed that the sample shown at CeBIT was indeed a reference model.

This is a very interesting move from AMD, and probably one of the best ideas for dual-card so far. We all know that Hawaii-based cards do need a proper cooler, unless the owner is deaf.

What surprised me, is that reference cooler (which could’ve been just a prototype) wasn’t even red, instead it was covered in black and gray, but I’m quite sure AMD will paint it into more bloody colors.



AMD Radeon R9 295X2 will compete with GeForce GTX 790
Well, I know, who would’ve expected! The rumor has it that NVIDIA will push forward GTX 790 launch, so we should see both cards in a very short timeframe. AIB partners were officially briefed about the new card this week, so it’s probably a matter of few weeks (if not sooner) till we see first cards on the market.

A single 120mm radiator for two Hawaii GPUs? That should be fun!
Maybe the rad is a Monsta and the supplied fan(s) are 120x38 Delta's.

TechPowerUp - ASUS ROG ARES II 6144 MB

It has 41c to play with if it was using the same ARES II model cooler.

Asetek pump has been updated twice since this model. This is 2nd gen pump.
All current Asetek AIO CPU cooler pumps that have been out for a year use the 4th gen.

If it is a watercooled Asetek. It will probably be using 4th gen pump and improved fans since this ARES II model.

Well, the Ares was/is two Tahiti's, so you'll be adding at least 60 watts extra for two Hawaii's running at a reference 1000MHz. Crossfire doesn't scale double for power, but you can get some ballpark estimates from the single card reviews and the peak (431W) pulled by the Ares II.

Just a comparison or two...G3D's Ares II and 290X CFX reviews (60 watts difference)

and HardOCP's ( 80 watts difference)

If it is a watercooled Asetek. It will probably be using 4th gen pump and improved fans since this ARES II model.

The GPU block isn't that much of a consideration in comparison with the heat dissipation ability of the radiator - no different from any other cooling loop.
The Ares II was hitting 70C in overclocked state, so fair to say unless the heat dissipation of the new cooler is radically better than the Ares II, this prospective card is going to run warm once the clocks get ramped up....and I certainly don't think that anyone buying a watercooled high end card wont be overclocking it.

Wow, Your try'n to find any excuse to hate this thing ?

NVious ?

ASUS - ARES2-6GD5

ROG ARES II: dual HD 7970 GPUs and hybrid air/ liquid cooling

• Hybrid thermal design: dissipating heat equal to 600W with 2-slot air/liquid cooling
• First card with 13% faster and 31°C cooler performance than reference GTX 690
• Acclaimed DIGI+ VRM joins superior quality 20-phase Super Alloy Power for precise digital control, enhanced performance, reliability, and card longevity
• GPU Tweak: modify clock speeds, voltages, fan performance and more, all via an intuitive interface

Even if they are that lazy to just use this old Hybrid cooler it should be fine. Cost a lot and hard to find but should be fine. Chances are they updated it.
Have fun hating or trolling I can never tell with you.

I don't like any dual GPU card on principle - not just this one.
Duallies are usually more problematic, suffer in ability (OC) to two single cards, have more issues with drivers, lower resale, and generally aren't a saving over two separate cards

NVious ?

Pathetic much?
Let's see how much praise you heap on the GTX 790 by comparison if you're squarking about even-handedness

Have fun hating or trolling I can never tell with you.

Given the amount of both that you do, that is surprising.

That's the smoke I remember right there.
Because you don't like dualies this one deserves your berating it even before anyone has seen and officially tested it?
Right so are we all banned from xfire and sli too then o lord ?

 

[the54thvoid]

Give it a rest people. It's completely normal to presume guilt before innocence is proven in the dual card wars.
The 790 will likely be more refined going on Kepler efficiency. Good chance too that AMD will for broke with a hotter, louder, more power hungry card, with Nvidia losing (game depending) on the performance front.

 

[HumanSmoke]

Well, since I promoted the use of two single GPU cards over a dual GPU card in the post YOU actually quoted, that would seem to be a case of terminal hyperbole on your part.

Do and buy whatever you like. I'm expressing a personal opinion allied with a knowledge of previous experience. You know what Santayana said about the not learning from the past?

Care to name a dual GPU card that didn't suffer in comparison to two single GPU cards using the parameters I listed (OC potential, resale, price, drivers...)?

Because you don't like dualies this one deserves your berating it even before anyone has seen and officially tested it?

So, you have a problem with people offering a negative opinion on an unreleased product...unless the people in question...are you?
On the GTX 750...

This is panic status releasing by nvidia

Still on the GTX 750...

Is this looking like the other side of the tegra k1 binning tree to anyone else, ???.Like poor core bin but max gpu array bin

...and still on the GTX 750...

Er the 750 and its ti cousin are also rumoured to have one six pin power plug and imho are unlikely to compare favourably to either of these in performance or price terms.

dude samsung and hynix both do new ic which has double the density, 8 1gb chips take up no more room than 8 521mb chips.

 

[Vario]

Core zero should make it fairly efficient I'd think.

I wouldn't call it "improved" just "different." That solution is not intended for anything other than a server case with a tornado of front to back ventilation. The fins are designed so that they will not work with top down ventilation like the 7990 had.

Overall, I think that the 7990's cooling wasn't all that bad, and above that, it was the first dual GPU card that was actually priced reasonably. I seriously considered buying one when the price dropped, but AMD lost my purchase due to the coil whine on the card.
