DX11: Aliens vs Predator

Aliens vs. Predator is a science fiction first-person shooter video game, developed by Rebellion, and published by Sega for Microsoft Windows, Sony PlayStation 3, and Microsoft Xbox 360. Aliens vs. Predator utilizes Rebellion's proprietary Asura game engine, which had previously found its way into Call of Duty: World at War and Rogue Warrior. The self-contained benchmark tool is used for our DirectX-11 tests, which push the Asura game engine to its limit.

In our benchmark tests, Aliens vs. Predator was configured to use the highest quality settings with 4x AA and 16x AF. DirectX-11 features such as Screen Space Ambient Occlusion (SSAO) and tessellation have also been included, along with advanced shadows.

  • Aliens vs Predator
    • Extreme Settings: (Very High Quality, 4x AA, 16x AF, SSAO, Tessellation, Advanced Shadows)

Cost Analysis: Aliens vs Predator (1680x1050)

  • $142 Radeon HD 5770 1GB costs $7.36 per FPS
  • $167 GeForce GTX 460 768MB costs $6.71 per FPS
  • $180 Radeon HD 6850 1GB costs $6.41 per FPS
  • $188 Radeon HD 5830 1GB costs $8.14 per FPS
  • $220 GeForce GTX 460 1GB costs $7.67 per FPS
  • $240 Radeon HD 6870 1GB costs $7.27 per FPS
  • $260 EVGA GTX 460 FTW 1GB costs $7.54 per FPS
  • $262 Radeon HD 5850 1GB costs $7.92 per FPS
  • $292 GeForce GTX 470 1GB costs $8.13 per FPS

Test Summary: Aliens vs Predator may use the well-known Asura game engine, but DirectX-11 extensions push the graphical demand on this game to levels eclipsed only by Mafia-II or Metro 2033 (and possibly equivalent to DX10 Crysis). With an unbiased appetite for raw DirectX-11 graphics performance, Aliens vs Predator accepts AMD and NVIDIA products as equal contenders. When high-strain SSAO is called into action, the Radeon HD 6850 compares to the 1GB GeForce GTX 460 at stock speeds, and while the EVGA GeForce GTX 460 FTW video card is well out of reach, the Radeon HD 5830 and 5770 are easily surpassed. At 1680x1050 resolution with extreme quality settings, the Radeon HD 5770 produced 17 FPS in Crysis compared to 22 FPS with the Radeon HD 5830, while the Radeon HD 6850 produced 26 FPS.

# Why 7.25 on the value?sweatshopking 2010-10-22 03:50
this card produces frames at a lower cost than anything else you tested, based on your own scores. Why do you rate it a 7.25 on the value front?

# RE: Why 7.25 on the value?Olin Coles 2010-10-22 07:04
True, the cost per frame value was quite nice, but there were several factors I considered for the value rating and you've got to keep in mind that it's a subjective score. I didn't like that fan noise was slightly louder than the 6870, and the price seemed just a little higher than I think it should be. Again, it's only my rating, and you can ignore it if you feel differently about the cards' price.

At 16x10 resolution, Hd 6850 is actually producing 56.1 fps in the BF2:BC benchmark, better than gtx 460. A typo there, my guess.

# 5830David 2010-10-25 06:30
well I wish I'd read this before I bought a 5830. not really sure where the 5830 would have placed in this test, but I assume it would be just below the 6850. my options at the site I purchased it were 5770 $139, 5830 $179, or 6850 $199. my motherboard doesn't have pcie 2.1 on 2.0 but I'm not sure if that would influence my choices.

2.1 on 2.0 should read 2.1 only 2.0

# 5830 wasn't greatsweatshopking 2010-10-25 07:02
the 5830 would come in quite a bit below the 6850, and with much higher tdp, and noise. It was a lackluster part, and that was one of the reasons for the refresh. that being said, it's still better than my 4850, so enjoy it!

I've actually got several results tested on the 5830, but didn't include them because this model is being phased out. I'll update the article with what I've got.

# RE: 5830David 2010-10-25 08:05
so my next question is how will my system likely perform. I'm upgrading from a 8800GT OC to a 6850 reference card on a P43 ICH10 MB a E8400 cpu with 4GB of Dual Channel DDR2 1066 Ram and a 3gbs Sata HD, onto a 1680 x 1050 22" LCD via DVI

should be able to play pretty much anything on high, at that resolution.

# RE: RE: 5830Olin Coles 2010-10-25 10:23
At that resolution, it should nearly match the 1680x1050 results I produced in this review.

That's good news. I've updated the test summary sections with 5830 performance results.

thanks, looks like it's $20 well spent to go from the 5830 to the 6850. besides the FPS increase, I will also get a overall better quality controlled product with a couple of extras that I probably won't use LOL.

How can the EVGA GTX460 be so much better than a normal one?

# Massive OverclockBruceBruce 2010-11-12 23:34
It's overclocked by the factory from 675 MHz to 850 MHz, giving it a pretty substantial (25% +) kick compared to stock cards.

# RE: Massive Overclockpero 2010-11-13 14:39
Is it physically different too? If a consumer overclocked a non-overclocked GTX460, would the results be the same?
Report Comment
 
 
# RE: RE: Massive OverclockOlin Coles 2010-11-13 15:49
Nope, it's just been overclocked. The results would be the same for any GTX 460 overclocked to those speeds.

# RE: EVGAOlin Coles 2010-11-13 08:49
Please see the Test Methodology section for specifications, but the reason it's better is because of a strong factory overclock.

also, how much power does it need to run crossfire?

# RE: RE: AMD Radeon HD 6850 Barts Video CardOlin Coles 2011-11-24 21:06
It will work just fine with PCI-E 2.0, and since each card uses 140W expect to use 280W in CrossFire.

I have a 750 watt power supply. A 1 terrabite segate 7200 rpm hdd 8 gigs of ddr3 1333 Corsair Dominator ram, and an x fi titanium sound card. do you think that there would be enough power to run cf or should i check and see how much power each thing takes individually?

Thank you very much for the response

Your 750W PSU will be more than enough for CrossFire on that system.
