AMD Dual-GPU Radeon HD 7990 to Launch in Q1 2012, Packs 6 GB Memory

Even 12 months ago, an Intel Nehalem-powered gaming PC with 6 GB of system memory was considered high-end. Now there's already talk of a graphics card taking shape, that has that much memory. On Thursday this week, AMD launched its Radeon HD 7970 graphics card, which features its newest 28 nm "Tahiti" GPU, and 3 GB of GDDR5 memory across a 384-bit wide memory interface. All along, it had plans of making a dual-GPU graphics card that made use of two of these GPUs to give you a Crossfire-on-a-stick solution. AMD codenamed this product "New Zealand". We are now getting to learn that codename "New Zealand" will carry the intuitive-sounding market name Radeon HD 7990, and that it is headed for a Q1 2012 launch.

This means that Radeon HD 7990 should arrive before April 2012. Tests show that Tahiti has superior energy-efficiency compared to previous-generation "Cayman" GPU, even as it has increased performance. From a technical standpoint, a graphics card featuring two of these Tahiti GPUs, running with specifications matching those of the single-GPU HD 7970, looks workable. Hence, there is talk of 6 GB of total graphics memory (3 GB per GPU system).

One can also expect the fruition of AMD's new ZeroCore technology. This technology powers down the GPU to zero draw when the monitor is blanked (idling), but in CrossFire setups, this technology completely powers down other GPUs than the primary one to zero state, when the system is not running graphics-heavy applications. This means that the idle, desktop, and Blu-ray playback power-draw of the HD 7990 will be nearly equal to that of the HD 7970, which is already impressive.

And a Bulldozer is not an 8-core CPU, because it's like saying that mine is a 12-core CPU... doesn't work that way.
It's closer to being real cores than it is hyper-threading though ( I call them half cores :) )


As I have 8 physical threads ( 8 integer cores)

How ever 2 integer cores share the resources ( albeit bumped up ones) of what would normally be 1 core.

So bulldozer does 8 threads in parallel where as a 4core 8 thread intel cpu does 4 threads at a time but in a really efficient way . ( Think of it as a really well organised tightly packed queue)


Sorry for off original topic in regards to original post. Will take conversation to PM if if anyone wants to discuss it.

This card makes me want to go take a vacation to New Zealand and chill at Mt Taranaki.

Anyone with me? Anybody? Yes? Maybe? Fine~

Just like the 6xxx and 5xxx series, the 7990 will most probably be 2x 7950's slapped together vs. 2x 7970's (for power and heat reasons). However, I would be very surprised if they just said screw it and made it 2x 7970's, just for the sake of being top dog. But IMO, they don't need to as they don't have any competition yet. We'll have to see what Kepler brings to the table, and I for one can't wait for that to happen. Hurry up Nvidia!!!

Isn't the 5970 an underclocked 5870? The HD 6990 is an underclocked 6970, not 6950, because all the shaders are enabled.

Ha ha not whilst the shadows are run by the cpu! :laugh:
that wasnt my problem...CPU load was fine, but Skyrim did consume 99% of the Video Memory due to that setting;)

Oh dam. Thanks for clarifying that for me. I'm not as smart as I thought I was haha. I dont know why I always thought that it was 2x 50's and not 70's. :toast:

wogh.... can't wait to crossfire this to play bf3 in max resolution @ 1080p... time to ditch my [going to be] obsolete 6990.... :toast:

Bulldozer's 8-Core is hardware where as Intel's Hyper Threading is software. People will agree to disagree in regards to this because not everybody agrees with AMD's concept of an 8-Core CPU. Personally I think it’s as much an 8-Core as a Phenom II x6 being a 6-Core, it’s just configured differently. Now if AMD would like to prove that this new Modular design is the way to go, then by all means, we are all waiting for updated performance figures and applications that should take advantage of this new design.

While I agree that Intel's Hyperthreading is a fancy way to address 2 threads to a core and AMD's Bulldozer is a module that has 2 Integer and 1 FPU units I still don't recognize it as 2 cores per module, even though it is very close to it.
Let's say, 1,5 cores per module is more appropriate...
Still I'd love to see improvements with the upcoming patch and surely I'd want to see AMD to address the enormous latency on the cache but this is another cup of tea and I'm going off-topic :)

Remaining on thread I seriously hope that AMD will stick to single slot solution for the HD 7990 like the HD 6990

trust me i been testing this for some time under different cpu's and such.

7990 is going to be slower then my 6990 hahahahahah ....

Dumb fucks that's going to pay 989.99 are in for a dumb surprise..... SLOWER!!!! but cooler. Keep your 6 series gpu's

the power can be used even in single monitor set ups.

1080p + 8xSSAA & Edge detect + EQAA + Morplological filtering + Ambient lighting + Physics + Tesselation + 16x Quality/Trilinear filtering + massive negative LOD .

Ya the power can still be used on single monitor setups.

Besides, this card will stay quite relevant for single monitor setups for years. The very low idle power will save the fan from dust/wear.

Just wondering something, why 6GB? I mean, it's nice but what right now would utilize it?

Really? HD 6990 is single slot, I thought I see Dual Slot air cooler. It would be nice to have single slot cooler so you can use your PCIe slots instead of having them taken up by the Dual slot coolers.

Everytime I enable this my games look like crap. Any idea why :confused:

You guys are exaggerating to much. I have a Core 2 Quad and a 5870 and I play ALL games on the market today with absolutely NO problems and glitches with MAX DETAILS settings (4xAA, 16xAF on a 1080p resolution). Stop being so geeky and OVER-pretentious!

Erm.

That's just false.

Why are people typing such bullshit?

So you are playing at less fps than the GTX480 and this isn't even a graph for maxed out details. (and the below TPU graphs from W1zzard are 1050 res.


Again


It'd be nice if folk stopped lying about their system's capabilities. There is no way your C2Quad and a 5870 are maxing out all gfx details and playing the above games for example on decent fps. Unless you have a magical PC.

... Wait, wut!?

You realise a single 7970 is already right up a 6990s arse right?

And you realise in games where crossfire works the 7970 has +90% scaling?

I complete wrecks two 580s in sli let alone 6990.

( wrecks Asus mars two as well)

Go read the crossfire reviews man :toast:

until Nvidia release their cards the 7000 series will be best on market.

I didn't explain it, the HD 6990 is single slot capable thanks to the location of the DVI and mini dp, once you put a waterblock on it becomes single slot :)

Morphological AA is a post processing, it is applied after the frame has been rendered.
It doesn't recognize text and so it smooths the text too making it blurry

You obviously fail to understand that any game that outputs more than 30fps is more than playable. I played both Metro and Crysis and didn't have any problem with that fps. What is your point? Btw, I am not a geek gamer, so use your "bullshit" on someone else. :shadedshu

Overclocked quantum bit
I'm waiting for the graphics tech that can gang two GPU's together on one card so that they can both use the whole memory buffer together and work as a single logical GPU. This will make the whole thing much more efficient:

- The whole memory buffer can be used, so wasting half of it on mirroring won't be necessary
- The two GPU's will work as one logical double-wide GPU
- Microstuttering should be eliminated
- The card will work exactly like a single GPU card, but with double the performance and its full performance will always be available without requiring any special profiles for specific games like we have now

Obviously, this kind of functionality won't be available with two physical cards, because the GPU's will be too far apart physically and on different boards.

This will be a true innovation and whichever company implements it first will wipe the floor with the other one. Well, here's hoping it comes to pass.

Didn't the older graphics cards do this no problem?

When they didn't really even market them as x 2 etc.
