HIS Radeon HD 6990 4GB ReviewIt has been a few months since the AMD Radeon HD 6990 initially launched. Since that time, a number of AMD’s board partners have launched their own Radeon HD 6990 cards, but as is typically the case with the first wave of products based on a new GPU, they all conform to AMD’s reference design, save for a water-cooled card from PowerColor.

While most of the Radeon HD 6990 cards on the market today are fundamentally very similar, we thought it would be a good idea to check out a retail-ready 6990 using AMD’s latest drivers to see how well the card performs (and behaves) with updated software. To that end, we got our hands on an HIS Radeon HD 6990 card and have put it up against NVIDIA’s best to see how things sake out in a handful of games and applications using the latest drivers available at press time for both...

"I just wanna know if AMD has fix their driver problems with Crysis 2 running on the 6990. especially quad crossfire, or dual 6990. Oh yeah , good luck finding one of these, newegg cant keep up with the demand."

OMG 4GB of Memory? I just looked up the price and even though it's expensive hit me with those benchmarks so I can dream Marco :)

That is one beast of a card thanks for the review. I could imagine that this thing puts off a lot of heat and the fact that it is blowing some of it back into the system properly placed fans are a must as mentioned in the article.

Actually it's 2GBs per GPU but with the way Crossfire works (rendering an alternating frame rather then the same frame for each card.) You actually get 4GBs instead of 2GBs.

Clever eh?

I was surprised it did not pull away more at the higher resolutions as 4GB is nothing to slouch at.

None the less it's still a beast of a card and remains on top.

yep this card is big powerful and generates quite a bit of heat . anyone considering one of these would likely have the high-end chassis fans PSU $$ etc to consider a GPU as this..Always great to see the best & appreciate the great review,benchmarks evaluation and insights..

You see the brilliance of the new naming scheme. 6990 implies that this is the pinnacle of the ATI 6xxx series. Hmmm...or maybe not, there's always 6995...

What a beauty, too bad the noise on this thing is outrageous, but I guess thats what happens when you cram 2 graphics card GPU's in a case that usually fits only 1, im sure that fean bears a huge workload keeping those puppies cool.

Anybody know what a single GPU in the 6990 is equivalent too, or what crossfire rig is on par with a single 6990?

I'm guessing a single GPU in the 6990 is equivilant to the 6970 and the 6970 (or 6950) crossfire is equivilant to a single 6990.

And also, I'm hoping that Artic Cooling releases a cooler for the 6990 as they did for the 5970. The cooler they released kept the two GPU's cool and it also sounded nearly quiet as well.

I know the stock clocks are spec to 6950 to keep heat in check.

My guess would be 6950 Crossfire = 6990.

According to this article http://hothardware.com/Reviews/AMD-Radeon-HD-6990-Review-Antilles-Has-Arrived/

" However, it turns out AMD was actually able to cram what is essentially a pair of Radeon HD 6970s onto a single PCB."

Also for those that are into water cooling this beast; i know that quite a few vendors (such as EKWB, Koolance, and XSPC), carry a wide range of waterblocks for this and other reference 6990 cards.

Intel i5 3570***, ASUS Sabertooth Z77, Corsair AX850, 16GB Corsair Vengeance DDR3, Corsair Force 3 Series GT  SSD (120GB), WD VelociRaptor (300GB), water-cooled HIS Radeon HD7950, AZZA Genesis 9000, EKWB Supremacy CQ CPU block, XSPC RX360, EKWB-DCP 4.0 pump, Windows 7 H.P. - 64 bit

Though the specs on this beast are impressive im afraid AMD over did it this time. the 4gb of memory with the gpu they have is really dispropotionate i am afraid this card will to much ram to feasibly se and thus be overpriced.

wow what a beast of a card. Kind of reminds me of the first 8800gtx's big heat producing monsters. None the less I would love to have one.

I am excited to see what a dual core proccesor can do in a graphics card, but i am a little speculative as to the possibility of one large proccesor that powers both graphics and fundamental proccessing for a computer.

The amount of RAM is relevant to the number of GPU's on the card. See, the card is two Radeon HD 6970 GPU's on one card (hence the 4GBs.) Fortunately Crossfire works in a different way to SLI (which duplicates the same scene across both cards, therefore limiting you to 1.5GBs for the 3GBs 590.) so you have extra access to that RAM.

And it's not a dual core card per say. It's two GPU's on one card acting like crossfire; there are no such things as dual core cards mainly because GPU chips already have hundred of shader units on one chip dedicated to graphics processing and it's not possible to add a second GPU to the mix while retaining that single GPU style, therefore the need for cards like this one.

No doubt this is an impressive card, but the sheer ~cost~ of it is likely to quickly rip your manhood out through your wallet.

I just checked newegg.com; they only have one Radeon HD6990 available, and it's going for....$739.99 (not including tax and shipping). Not too shabby of a deal really, considering you're (basically) getting 2 video cards in one.

http://www.newegg.com/Product/Product.aspx?Item=N82E16814125370

 

Here in Canada; I saw at Memory Express, they're carrying 3 different brands of the HD 6990 (HIS, Sapphire, and XFX...HIS being the most expensive @ $779.99)
