Unigine - Heaven Benchmark Results

Unigine Corp. released the first DirectX 11 benchmark "Heaven" that is based on its proprietary UnigineTM engine. The company has already made a name among the overclockers and gaming enthusiasts for uncovering the realm of true GPU capabilities with previously released "Sanctuary" and "Tropics" demos. Their benchmarking capabilities are coupled with striking visual integrity of the refined graphic art.

"Heaven" benchmark excels at providing the following key features:

  • Native support of OpenGL, DirectX 9, DirectX 10 and DirectX 11
  • Comprehensive use of tessellation technology
  • Advanced SSAO (screen-space ambient occlusion)
  • Volumetric cumulonimbus clouds generated by a physically accurate algorithm
  • Dynamic simulation of changing environment with high physical fidelity
  • Interactive experience with fly/walk-through modes
  • ATI EyeFinity support

The distinguishing feature of the benchmark is a hardware tessellation that is a scalable technology aimed for automatic subdivision of polygons into smaller and finer pieces, so that developers can gain a more detailed look of their games almost free of charge in terms of performance. Thanks to this procedure, the elaboration of the rendered image finally approaches the boundary of veridical visual perception: the virtual reality transcends conjured by your hand.

Unigine Corp. is an international company focused on top-notch real-time 3D solutions. The development studio is located in Tomsk, Russia. Main activity of Unigine Corp. is development of UnigineTM, a cross-platform engine for virtual 3D worlds. Since the project start in 2004, it attracts attention of different companies and groups of independent developers, because Unigine is always on the cutting edge of real-time 3D visualization and physics simulation technologies.


As we look at newer and newer benchmarks, from studios that have had an ongoing relationship with ATI, we are seeing better and better scaling factors. Once again, we turned on all the eye candy for this benchmark, because we didn't want to miss a trick. I have to say, the graphics were extremely impressive; the scenarios they scripted really showcase the new technologies available, particularly tessellation.

The CrossFireXTM scaling numbers are the best we've seen yet, and are really pushing the theoretical limit in this benchmark. At 1680x1050, the three card setup gives a 189% improvement over a single card. 200% is the limit, and we're within spitting distance of that, here. What's beyond belief is that this kind of performance is being realized with the first official driver release from ATI.

In our next section, we investigate the thermal performance of the Radeon HD5770, and see if that half-size 40nm GPU die still runs cool, when two and three cards are stacked one directly on top of one another. The GPU cooler for this card showed that it had lots of headroom in our earlier tests, so I don't anticipate the usual overheating problems one would typically see in a multi-GPU arrangement. But, that's why we test...just to make sure.



# Low Scores on ati 5770 xfireronald jan 2010-11-27 20:43
i cant seem to know the problem with my set up why im getting a low scores on benchmark test with re5 using ati 5770 GPU.

scores with the same set-up: 1920 x 1200 with all settings were max out 8xAA was only 24.1fps with the single card and 42.1 fps with crossfire setup.


GPU: Sapphire ATI 5770 Vapor X crossfire config with 1 crossfire cable connected
Proci: thuban 1090t h50 water cooled
mobo: msi 790gx-65g
hdd: samsung 500gb 7200rpm 3.5
mem: ocz obsidian dd3 1600mhz 4GB ( 2by2Gb)
PSU: thermaltake litepower 600w
Monitor: Sony 32in bravia lcd TV
software: dx 11 cat 10.11 win 7

can somebody please help..could it be some components maybe bottleneck?

# TV is max 1080pBruceBruce 2010-11-27 20:57
I don't know of any Sony Bravia TVs that will display 1920 x 1200. The newest ones will max out at 1920 x 1080. If you have the video card trying to drive this TV with 1920 x 1200, either the TV or the video card is probably freaking out. Try setting the video resolution to 1920 x 1080 if you have one of the newer 1080p TVs. If it's am older unit it's 720P and 1366 x 768 pixels.

Ronald ren i have the xfx video cards running in xfire and the same msi motherboard and a 600watt ocz PSU, and i too have the same issue. No matter what game i am running (is playable in crossfire) it seems i get slower performance in crossfire and my single radeon 5770 runs faster. i know with t that mobo it is a 16x lane but when ran in crossfirex it will make the cards 8x X 8x in their respective lanes. Have you ever resolved the issue? I can't figure it out.
