AMD Radeon HD 7990: Eight Games And A Beastly Card For $1,000
By , Igor Wallossek

It’s a good thing that we have so much information at our disposal. Otherwise, the average frame rates in Crysis 3 would confound us. On one hand, we see two Radeon HD 7970s in CrossFire rendering more than 46 FPS, but giving us a more modest 23.4 FPS once we remove dropped and runt frames. On the other, AMD’s Radeon HD 7990 yields a similarly poor 22.3 FPS in both the hardware and practical frame rate measurements. Then, we install the prototype Catalyst driver and get chart-topping results.

It isn’t clear why the Radeon HD 7990’s hardware and practical frame rates are so low from this chart. But when we drill down into the raw frame times, we see the dual-GPU flagship bouncing between very precise ~35 and ~50 ms frames, occasionally jumping to ~65 ms. This is being done deliberately, perhaps to circumvent the severe number of runts encountered by the CrossFire config. Radeon HD 7990 surprisingly encounters few drops or runts at all, instead simply suffering low all-around frame rates.

Perhaps the prototype driver suggests what AMD would like to see in the long-term. It does drop some frames and cut others off prematurely (indicated by the divergent dotted line). However, we clearly see it’s much more competitive against Nvidia’s hardware.

We expect a single GPU to serve up the lowest variance between successive frames, and GeForce GTX Titan delivers. Two GTX 680s in SLI leverage Nvidia’s metering technology to achieve solid numbers as well.

Meanwhile, a range from about 5 to 45 ms really hurts the Radeon HD 7970s in CrossFire. The strangely specific peaks and valleys between 35 and 50 ms help keep the 7990’s frame time variance and check. But it’s the prototype driver we should probably be looking forward to most.

    donquad2001this test was 99% useless to the average gamer,Test the card at 1900x1080 like most of us use to get a real ideal of what its like,only your unigine benchmarks helped the average gamer,who cares what any card can do at a resolution we cant use anyway?

    If you're looking to game at 1920x1080, I can save you a ton of money by recommending something less than half as expensive. This card is for folks playing at 2560 *at least.* Next time, I'm looking to get FCAT running on a 7680x1440 array ;)

    Here's an idea. Take away the 8 games at 40 bucks a piece and deduct that from the insane 1000 price tag.

    Sort of seems like a mess to me. The game bundle is nice.

    Power usage?

    Thats some nice gains from the prototype driver.

    Power is the one thing I didn't have time for. We already know the 7990 is a 375 W card, while GTX 690 is a 300 W card, though. We also know AMD has Zero Core, which is going to shave off power at idle with one GPU shut off. I'm not expecting any surprises on power that those specs and technologies don't already insinuate.

    Nice article. I was hopping that they would have addressed the whining but they haven't and that's a shame. Performance wise it can be matched by GTX 680 SLI and GTX 690 without the huge time variance and runt frames. Let's hope they fix their whining issue and FPS without forcing users to turn on V-sync. For now I know where my money is going consider that I have dealt with AMD before:XFX and Sapphire and didn't like the results (whining, artifacts, XF stops working etc). Sorry but I gave the red team a try and I will stick with Nvidia until AMD can prove that they have fixed their issues.

    Why are all you people, that this card is not made for, complain about the price tag? AMD / Nvidia for sure don`t really make a profit if any out of these monsters. They are just for show like in the CPU business.
    People mostly buy Intel (I3/i5 a lot more than i7) just because Intel can provide top of the line CPUs in the i7 Extreme range. Same goes here, if some hears that AMD has a better 1000$ card than Nvidia, they will probably spend 100-200$ for an AMD card and not Nvidia.
    Power ... unless you`re not a guy who saves 2 years in a row for this card to have a 6 months nerd gaming glory you won`t care that much how power hungry this card is.

    Is just like asking Ferrari or Lamborghini how many mpg their cars do.

    1.I wonder if inserting all those pauses in the rendering pipeline for smoothness harms the compute performance.

    2. Regarding the fan noise and the hum : It would be interesting to know how much noticable is the fan noise and the hum with increaseing listner distance. IOW, which noise is more noticable at near/medium/far distances ?


    Drivers still are AMD's biggest weakness. I would have expected AMD to havetop-notch , A-one drivers to go with the HD7990. After all, this is AMD's halo product. The first impression is what matters. The conclusion is basically "Card is good. Drivers are poor, with better coming in future". So ultimately its selling a promise, which may/may not succeed. It appears to me that AMD doesnt value its own products.

    Ohh, and a video conversion test would have been nice too. (Is there any software available that supports CFX ?)
    Also, has the Video Conversion Engine in AMD taken off ?

    It's very interesting that AMD couldn't find a capacitor that wouldn't cause this noise. I feel once third party vendors get the reference they'll find ways of removing that. Hope they fix it soon or else nVidia will have a new line of cards while AMD is having problems with neatly two year old chips!!!

    Unfortunately I'm really not sure the whining issue is something that can be fixed with a driver update. I think it has more to do with the hardware on the board than anything else. But it's good to see that AMD has finally recognized the frame time variance and micro-stutter problem, and are actively pursuing a solution. Although the test in the review was limited, I think it's telling that every gamer tested was able to recognize the difference between AMD and Nvidia cards, and even the difference brought by AMD's own prototype drivers.

    I know and that's what I meant by hopping that they would have addressed the whining with this card. It happens to all their cards, well the ones that I have owned especially the XFX and if they knew what causes then they should have fixed it.

    Let's hope that the prototype driver will also translate to better drivers for all their GPUs and address the frame rate issues. Other than that, it is a good card but I think, for my personal use since I was waiting to see what this can offer, I will just get the GTX 680 or the GTX 780 next month and will definitely go back to AMD if they address those issues.

    For everyone seeking power and heat results:
    http://www.anandtech.com/show/6915/amd-radeon-hd-7990-review-7990-gets-official/16

    It consumes a lot of power under load, substantially more than the GTX690, but like Chris said that's to be expected. The big difference with the 7990 seems to be acoustics in relation to temps at load. It's a massive improvement over the 6990, and pretty much on par with the GTX690. Unfortunately the coil whine seems to undo a lot of the improvements made to the stock cooler, but all things considered it's pretty impressive what AMD was able to do in this area, especially in comparison to unofficial solutions from other vendors (dual slot, only requires 2 8-pin).

    Sorry, that's a reading fail on my part. Thought you said, 'hope they'll address the whining' or something to that effect.

    A Price tag of $849.99 would had been quite aggressive & increased its value significantly.
