Today marks one of those funky occasions when you’ve probably been aware of the “new” product we’re going to show you for quite some time. And we’re not talking about a few days or weeks here either. In fact, it was all the way back in December of 2011, when AMD introduced the original Radeon HD 7970, that we first dropped hints that the dual-GPU powered Radeon HD 7990 was in the works. We dropped those hints back then because AMD dropped them on us in the lead-up to the Radeon HD 7970’s release. That little tidbit alone should give you a good idea as to how long the Radeon HD 7990 has been simmering in AMD’s kitchen.

Though the product has obviously been in development for quite some time, the Radeon HD 7990 is still an exciting proposition. Despite the relative age of its GPUs, the 7990 still has the potential to be the fastest graphics card to hit the market...

Actually I wouldn't be surprised if the fix for the stuttering actually increases performance. It is an area that AMD was not looking at before and they have been finding performance that was "left on the table".

Just read through a few reviews. Looks like CF issues are stopping this card just short at times. I thought it would go for 800-900, not 1000. At that price, the 690 performs more consistently, but if you play at above 1200p the 7990 is a better choice because it pulls ahead there by 5-10% at times (i.e. when there arent cf issues). Hoping new drivers will fix that.

Well everything I read AMD says the issue is just software that is needing to be optimized which I would think might give it more performance like InfinityzeN1 said. I really think AMD is getting on its game with GPUs lately and when they catch up with the software side they just might be really giving Nvidia a run for their money. 

The price wasn't a shock considering the earlier reports that the 7990 can beat both the 690 and Titan. Time will well what happens in the next couple months with what AMD does with the drivers.

Also top notch review Yes Now I just need to know where I can get a couple of these to "fall off" a truck somewhere :P

Nice review Marco! Sure are some beastly cards out there nowadays. Thanks for the hard work getting the latency info included!

Working on an update now using the prototype drivers that address some of the frame pacing issues...

Very nice article... but I'm just not impressed with the card. Seems like the only time AMD/ATI video cards become the best performing is when they just double up the number of GPUs on the card. Additionally, the drivers for these cards have a very long history of falling just short of the mark.

Nvidia could cheese out and just slap two GPUs in one of their cards like AMD just did... instead they innovate and develop faster/better/more advanced GPUs.

Maybe I've just been soured about AMD over the years, but this doesn't strike me as innovative and I'd rather have an Nvidia based Titan or 690 or even a pair of 680's over this card.

In what way is a 690 not just slapping 2 GPUs on one card?

Yeah man that is all the 690 is. Just two 680s combined. If AMD fixes the driver issue which hopefully they will then Nvidia might be taking a backseat until the 700 series are released. In the end it will always go back and forth though.

Ahh my mistake. I guess Nvidia did cheese out then. I wasn't aware that the 690 was just 2 GPU's on the same card.

Heh well I know both Nvidia and AMD have done dual GPU cards for the last few series. It's not like one does it only then they decide to copy them. Nvidia brought out the 690 a year ago and AMD just now because of the demand since ASUS had the only real viable dual 7000 series GPU in the Ares II.

I always go by MINIMUM fps average and maximum frame rates are irrelevant in my opinion and if you look between the very expensive cards on most games tested the difference is minimum to say the least and that's why id never buy something like that even in a dual card setup its pointless. Besides when are these manufacturers going to fit as STANDARD custom coolers like the Arctic versions?

Thats cool that they're making this, but I remember a different re-seller making their own version of the 7990 because AMD was taking to long to release it.

Good info Marco and the video was a nice touch. So now the real test will be with those prototype drivers once AMD gets to optimizing them then see what the 7990 does on the bench! Yes

I have to admit... that is some silky smooth looking framerate.

I have been wondering the same thing also. I know the 7950 does about 525ish and the 7970 is about 650ish. I have seen some people say the 7990's will be around 1200 but haven't seen any definitive benchmarks on them yet.

Can't wait for this thing to come out, it's going to crush nvidia's cards, the shuttering can be fixed using RadeonPro and enabling dynamic vsync and turning on triple buffering.

With two of these in a system, I think that we could easily mine some bitcoins and gain our money back! XD

Probably not, but you sure could mine a VERY respectable amount with this beauty :D

Someone who buys one of these beasts should start a HH folding team, and leave it on while they sleep!

At the rate Bitcoins are going with difficulty It would still be awhile.

Supports 4 concurrent monitors ehh? From what I see it outperforms the GTX 760 and beyond because although they may also support concurrent 4 monitor display, they're drivers are super buggy! Whereas AMD has been great with their multi monitor support! I'd suggest going for this baby if you really want your wide triple screen display when you go WAR MACHINE mode in Battlefield 3!

I like the new 7990 but i would still stick with Nvidia. much improvement since the last Amd Graphics card though

I'm shocked to see these cards having the similar scores.
