Known under the codename "New Zealand", Radeon HD 7990 represents AMD's highest-end part from the Southern Islands architecture. Consisting out of two Tahiti XT GPUs and 6GB GDDR5 memory (special edition 7990s could reach 12GB), Radeon HD 7990 goes head to head against the GeForce GTX 690.

By default, AMD has the advantage in terms of 50% more video memory (GTX 690 has 4GB), significantly higher memory bandwidth and the new Turbo mode, technology similar to the Turbo mode used on NVIDIA Kepler-based cards with a few major differences.

Our sources are telling us that the boards are starting to be sampled, all in preparation for the product launch in the second half of July. We will release more details as the launch day approaches, as well as the final retail price, which still isn't decided as we write this story. While we know AMD's press deck, the company has a long tradition of changing the price at the last moment.

At the same time, a lot of AMD partners are running the card in their labs but aren't aware of the actual product launch. We will see in just a few weeks time.

I highly doubt it.

Nope.
Probably only 3GB usable, both Nvidia and AMD make their dual gpu cards sound like it has twice the usable memory.

Right...essentially its a 6GB card.

I waited and waited for this card. Not interested anymore. Will wait for next round.

First tell AMD to crank its GPU power. 12gb? LMAO! AMD can't even run current gen Arkham city
Neither can Nvidia. Game suffers from awful frame drops on every card I've played it on. Have no idea what it's issue is especially considering how well optimized Asylum was.

Yes I can read thanks. I don't see anywhere where it states for certain that its all usable.

MOAR COARZ, MOAR GHZ, and now MOAR VRAMZ?

I guess their gpu department is taking after their cpu department.

OT: 6gb of vram (or 12gb per card) is complete hype and useless. By the time there is any advantage of having more than 3-4gb of vram, dual 12gb 7990's are going to be obsolete.

Reminds me of the 4gb nvidia gt430......

Could Reach 6GB USABLE VRAM , but very unlikely , maybe Asus will release a beast Ares with *12GB* VRAM who knows, but reference design will have 3GB usable VRAM for sure.

Gimmick alert!

Dont need this for another 2 years..

Not until games are build around higher resolutions.

Which we know will not happen because games are built around Console resolutions

6GB per GPU. Just like two separate cards with 6GB each. Unless you toss a 3GB card in the mix you will be able to use all of that 6GB.

yes. Unless they did something different than they have been for quite a few generations.

I've used close to 2.5GB on various games with my 7970 at 1920x1200. I could imagine quadfire at 5760x1200 with AA taking up more than 3 fairly easily.

Its not completely useless unless you don't understand what they're using it for. AMD has 5x1 surround which nvidia currently cannot do, and 6gb is a prerequisite for 6 screen surround.

Just ask callsignvega, he's a big fan of it - and you can't get it with nvidia cards. Personally, I would never buy this card but if they price it right (800-949$) for the 6gb version, it could be a viable alternative
to the 690. Especially since it is using GE chips.

Eyefinity supports up to 6 screens. Stop saying there is no use for a lot of vram.
This card isn`t for everyone, if you don`t need the 6gb of effective vram, don`t get it.

You can only use 3 screens display with NV hence the lower vram models offered for their high-end market. AMD supports up to 6 screens which is their higher-end market. If there is a market for 6 screens set-up, this is what AMD has to offer for this market segment. Period.

actually, if retina type displays come onto the market from other companies (which they will) or even 4k monitors then using 3 x 4k monitors would be Ahem... 25894080 Pixels rendered per frame

at least 30FPS.. means = 776822400 Pixels per second

so yea.. given textures, larger tessellation models, multi monitor, larger resolutions etc... i can see this. Also what about cloud game streaming perhaps companies are clamouring to sell huge VRAM cards so that millions of players don't need scuppered textures?

and finally remember, these boutique cards can come with bells and whistles they still get sold to the rich / e-peen crowd. Further more even scientific / military institutions might use huge VRAM for modelling 360 degree simulators and insane resolution too, that's a few sales right there.

its not all about crysis 2 and skyrim @ 1080p

*Quotes entire thread*

6GB VRAM IS USELES1!!!1!!

Y'all do realise this card will be aimed at those running 7680x1440 or 7680x3200 Right? You think 3GB Vram is going to cover that kind of frame buffer? Bahahahahaha thats what 12 times the size of 5760x1080 and i was getting on average 2000 to 2400 Vram used..

Niche card for niche market.

I will sell off my two 7970s with their water blocks, and have Two of these with EVEN BIGGER WATER BLAWKS and i will place thine holy Crossfire bridge onto them and press the all mighty power button and watch the lights dim as my monstrosity comes to life..

can you imagine (3)4k screens in eyefinity?!

DROOL WORTHY!

Until then, they will need to clock the pants off of this. Hopefully it also comes with the release of 6gb 7970/50's at the same time.

To think I'm playing @ a measly 1080p.

You are all assuming that a 7970 or a few of them have enough power to even push that many pixels for a 4k resolution.

How do you know 4 7970's aren't limited by gpu power? You don't.

You say vram will hold back the 7970 at a crazy resolution, and I say the gpu power will hold it back. No one has any clue which is right.

I'm surprised there are not any reviews of quad fire 7970's with 5 monitors that could lend any insight to whether or not 4 7970's even have enough power for that type of resolution with any sort of maxed out settings.

I am fairly sure we can push that kind of resolution, But the question is what happens when you turn AA on? or start upping the detail settings, Are you still going to have the grunt? are you going to have the Vram? I would suggest looking into reviews of 7680x1440/1600
