Unigine Heaven Benchmark Results

The Unigine "Heaven 2.0" benchmark is a free publicly available tool that grants the power to unleash the graphics capabilities in DirectX-11 for Windows 7 or updated Vista Operating Systems. It reveals the enchanting magic of floating islands with a tiny village hidden in the cloudy skies. With the interactive mode, emerging experience of exploring the intricate world is within reach. Through its advanced renderer, Unigine is one of the first to set precedence in showcasing the art assets with tessellation, bringing compelling visual finesse, utilizing the technology to the full extend and exhibiting the possibilities of enriching 3D gaming.

The distinguishing feature in the Unigine Heaven 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. The "Heaven" benchmark excels at providing the following key features:

  • Native support of OpenGL, DirectX9, 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

Due to the repeatability of this benchmark, the comparisons that result are extremely reliable for the chosen test settings. Through most of the benchmarks the 9800GT and Go! Green HD 5670 have been relatively equal in performance sometimes with one leading and sometimes with the other leading. If the parts are truly equal then the minor differences in performance are due to variation rather than real performance differences. The Heaven benchmark has very low variation and better shows the true differences in performance for at least one method of benchmarking.

With this in mind the HD3850 as caboose and GTX 260 as the engine don't come as any surprise. However, the 9800GT clearly stands above the default AX5670 and the overclocked AX5670. This seems about right since in previous tests when the 9800GT led it typically beat out even the overclocked AX5670.

# Power consumption and heat testingMatt 2010-05-14 12:34
I am a little sad that in the review the Powercolor NON-Go! Green 5670 card wasn't compared to its Go! Green sibling. This would have been a much more valid test to compare actual temperatures and power consumptions. Not that it doesn't seem like the Go! Green 5670 power consumption savings numbers seem a bit inflated, but it still isn't a very validating test (at least of the Go! Green 5750 it seems like the power consumption numbers do seem to be about 25% lower than an actual side-by-side tested 5750 (non-Go! Green) based on a benchmark of that card).

Final comment is on the design (owning a Go! Green 5570), fanless? Sure quieter, but a 1w silent fan could probably save 2-3w on a low power card and 5-8w on a high draw card by reducing temperatures 10-15c. My 5570 benchmarks in my case at 56c using furmark and with a 1.4w 80mm held up against it drops to 35c stable (21c drop). That has gotta be worth a few watts through better electrical efficiency running 21c cooler.

My video card has the same type of residue as that card, and it quit working after two years.

What brand and model was it?
Can you tell us more about the failure mode?

My computer came with a nvidia 9800 Gt. Since about a week ago I have been unable to play a video game or use windows media center. If I ever start a video game or windows media center the program crashes and I get the error message, "nvlddmkm.sys has stopped responding and has recovered." Some times I get A blue screen message and the computer has to restart. I have reinstalled drivers and even restored my computer's software to the original factory condition. About a year ago I noticed my computer screen would get dark, as if i was wearing sunglasses. I would restart my computer and the screen would look normal again. I replaced my video card and found white layers of crusty residue.
