Aliens vs. Predator Test Results

Rebellion, SEGA and Twentieth Century FOX have released the Aliens vs. Predator DirectX 11 Benchmark to the public. As with many of the already released DirectX 11 benchmarks, the Aliens vs. Predator DirectX 11 benchmark leverages your DirectX 11 hardware to provide an immersive game play experience through the use of DirectX 11 Tessellation and DirectX 11 Advanced Shadow features.

In Aliens vs. Predator, DirectX 11 Geometry Tessellation is applied in an effective manner to enhance and more accurately depict HR Giger's famous Alien design. Through the use of a variety of adaptive schemes, applying tessellation when and where it is necessary, the perfect blend of performance and visual fidelity is achieved with at most a 4% change in performance.

DirectX 11 hardware also allows for higher quality, smoother and more natural looking shadows as well. DirectX 11 Advanced Shadows allow for the rendering of high-quality shadows, with smoother, artifact-free penumbra regions, which otherwise could not be realized, again providing for a higher quality, more immersive gaming experience.

Benchmark Reviews is committed to pushing the PC graphics envelope, and whenever possible we configure benchmark software to its maximum settings for our tests. In the case of Aliens vs. Predator, all cards were tested with the following settings: Texture Quality-Very High, Shadow Quality-High, HW Tessellation & Advanced Shadow Sampling-ON, Multi Sample Anti-Aliasing-4x, Anisotropic Filtering-16x, Screen Space Ambient Occlusion (SSAO)-ON. You will see that this is a challenging benchmark, with all the settings turned up and a screen resolution of 1920 x 1200; it takes an HD5870 card to achieve an average frame rate higher than 30FPS.

Now we get into the full DirectX 11 only benchmarks, so we're looking at the full potential for graphics rendering that's available on only the latest generation of video cards. AvP is a tough benchmark, but it has been a fair one so far, and it's very useful for testing the newest graphics hardware. The relatively high frame rates you see above are a testament to the very high performance of the latest and greatest cards, especially when paired up in SLI or CrossFireX.

The performance of the PowerColor Radeon HD 6990 really jumps up in this Aliens vs. Predator benchmark. The purpose-built multi-GPU solution beats the CrossFireX pair of HD 5870 cards by 36% and it beats the highly overclocked Gigabyte GTX 480 SOC by an astounding 87%. This is definitely one of those games that need the right blend of hardware elements to come together for peak performance, and the Radeon HD 6900 series seems to have the right mix. AvP needs shaders more than tessellation, and the new VLIW4 units from AMD really sing on this benchmark.

In our next section, Benchmark Reviews looks at one of the newest and most popular games, Battlefield: Bad Company 2. The game lacks a dedicated benchmarking tool, so we'll be using FRAPS to measure frame rates within portions of the game itself.

Well done Bruce. After all the effort, sacrifice, and no telling how many years of enthusiasm/experience you bring to the fray, I feel compelled to offer a sacrifice of my own. Since the card is out of warranty, I volunteer to take it off your hands for long term testing, say a couple of years, and deal with any and all warranty issues in your stead. I know, I know, my altruism knows no bounds.

(wink, wink, nudge, nudge)

Good job.

Thanks for the props, Robert. As for your boundless altruism, I'll go you one better. You put gas in my wife's car for the time that you have the card, and it's a deal. [%^)

I know this was written for the PowerColor card but I just received my HIS yesterday and installed it last night. I guess my bottle neck is my resolution and my monitor. I have a 28" 60Hz, 1920x1200 Hanns-G monitor with 3ms response. I just don't see the gain from this series and going back to my 2x 465 GTX Nvidias or my 2x 580 GTX's in SLI. For the ATI fans I also have 2x 5850's in X-Fire and they also run like beasts. Its kinda like having a Race Car that does 205+ MPH but because you live in a heavy school zone there are always police which limits your choice to either follow the law or get arrested (Kind of a bad analogy but I'm sure you get my drift).

So now I have spent $720 on this card, damn I need a new hobby, I've now spent over $2,500 on video cards in the last 6 months.

I'm curious what kind of games you're playing, because that could be an indication of your bottleneck. Anything will play Battlefield or Starcraft at high frame rates, but the same cannot be said for titles such as Metro 2033.

I'm playing Battlefield Bad Company 2 and a few other FPS games. I figured that was my problem. And BFBC2 is more CPU intensive, I playing Battlefield on my AM3 1090T 6 Core which is more than enough for that game. I need to start HA (Hardware Anonymous) for geeks, but I'm afraid it would be a blood bath of which brand name was better, lol.

# A thoughtCom-Tek Chris 2011-03-22 06:59
How come we are pitting this against the Nvidia 400 series and not a set of 560ti's in SLI or a a single 580 GTX? I notice that the scores are up against a set of 460 GTX's in SLI and a couple of 6xxx series in cross-fire mode but none of the big cards from Nvidia in SLI. Was this because of a price to power thresh hold? Or because of availability in cards? I know my 2 580 GTX's his the $1,100 mark when I purchased both so maybe it is unfair to compare it to a single card that is $400 less, but still it would be nice to have the scores posted for comparison for both sides of the fan base. Hands down though, I love this 6990, its fast, sweet, and feels like there is a lot of technology in it. Even Nvidia Fan Boys would be impressed with the sheer speed of this card.

If we had two of everything, we'd put them in SLI or CrossFire. Since one card arrives as another is ready to launch, we're restricted by deadlines and must move to the next project.

Do you have to send back the cards your given? If not what do you do with them? Or do I dare ask, lol.

Only a few products get returned, but it's a matter of finding time to review more than one product of the same series before the next arrives. These reviews take more time than you could imagine (I invite you to try sometime), and after one article in published a manufacturer usually has something new in our hands.
All of my video cards sit in a giant cardboard box, and get sold about 16 months after they've launched and gone EOL.

I have done Bench Marking in the past with all new hardware, always trying to squeeze that extra 100 points out, lol, I don't do much anymore just because of the time it takes. I am a business owner and there are days where I start at 6am and get home at 10pm only to find that I have a 1/2 dozen build outs that are to be done by the next am, so I pull a 24hr shift that turns into a good 36hr shift, lol, did I mention I have a wife and 5 kids?...................so the drama continues in the life of "Im a computer engineer/network security consultant/Father/Guy who likes to game/Guy who races cars in the SCCA in the season which is here now/Guy who builds computers and provides support for local residents and business's and also donates computers to new local schools that burnt down 2 years, lol, yes I love life and all it offers..........did I mention I love Chinese food and hot pockets?

Replace kids with friends, keep computer engineer/network security consultant/SCCA racer, and add target shooting enthusiast. Also replace Chinese food with Thai, and hot pockets for Wheat Thins, and we're on the same page.

Olin's spot on about product availability v. time to do the review. As Einstein said, "The reason time exists is so that everything doesn't all happen at once." My corollary to that is, "Space exists so that everything doesn't all happen at the same place."

So, check out Olin's HD 6990 reviews for comparisons to the GTX 570 and 580 cards. I was surprised that the 580 SLI didn't wipe the mat with the competitors. It was faster, but not in another league, you know....

I'm very curious to see how well NVIDIA manages the balance between electrical power, heat and processing power with their rumored dual-GPU card. At this stage of the game (40nm GPUs), there's only so much juice that you can pump through a single card and the winner is the one that's more efficient per watt. We'll have to wait another week or so, to see.

FWIW, I prefer Triscuits....LOL

My wife pushes the wheat thins/Crackling Oat Bran Cereal.....a lot! And I just tried Thai recently, the curry wasn't to bad. My goal is to lose 30 pounds this year. I just got over the Flu and I have kept 12 pounds of that off, lol, its going to be a good year. Now if I can just get my hands a new AM3+ 8 Core, another 6990 for X-Crossfire Mode, now that would finish the year off with a POW!

What PC Case do you have in that picture, I hope its not really expensive. If it is do you think you could link a cheaper Pc case?

It's a CM Storm Sniper, which I reviewed here: benchmarkreviews.com/index.php?option=com_content&task=view&id=398&Itemid=61

It's not cheap, unfortunately, unless you find a deal. The good news is that there have been a ton of inexpensive gaming chassis reviewd on this this site recently, and I'd bet at least half of them would be able to handle this card, at 305 mm long.
