DX11: Unigine Heaven 2.5The Unigine "Heaven 2.5" 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, the 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 fullest extent, 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 to 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 veritical visual perception: the virtual reality transcends conjured by your hand. The "Heaven" benchmark excels at providing the following key features:
Although Heaven-2.5 was recently released and used for our DirectX-11 tests, the benchmark results were extremely close to those obtained with Heaven-1.0 testing. Since only DX11-compliant video cards will properly test on the Heaven benchmark, only those products that meet the requirements have been included.

Based on newegg reviews owners got 900-920 mhz at default volt. I'm hoping to get the same. Extra 20 to 40mhz for a 0.2 volts extra is too much. Did toy try to oc without volt tweaking?
Can't wait to bench mine.
More seriously, I doubt you could get to 1000 watts without those liquid-He/Ni cooling ideas. Still, if you could get it to 600 or 700 watts using air or water, that would be amazing. It's already drawing more power than most people's entire systems - it'd be both humorous and educational to see if it could outdraw most enthusiast systems.
Anyway, another enjoyable article. You guys run an excellent operation here at BMR.
I can not test for anything over the power draw I had on during this test due to thermal constraints. Even so during our test I was drawing almost 500w just for this card.
Thank you for the compliment it means a lot to know that our readers appreciate our work.
Nice to see an unashamedly "enthusiast" review.
Seems a little late to the party ( evga ). I can't see getting the classified when Kepler is around the corner now ( the first round of consumer cards and then the enthusiast cards soon after )
FYI Even if you wants to buy this gpu you can't it has bin sold out since launch and available in limited quantaties. Meaning when kepler hit I should have no problem selling the thing due to the limited quantities and demand @ a good price. Besides how would I play skyrim with all the hd mods out there already as well as bf3 @ max!

I hope not another fermi
OC is like over speed limit.....if ya going 10% over the 60 mph peed limit, that's 1.10 x 60 or 66 mph ....66/60 = 1.10 or 10% over speed limit
% Overclock = 100 x (OC Speed / Stock Speed - 1)
100 x (940/772 - 1) = 21.76%
Or another way ....
% OC = (OC speed - Ref Speed) / Ref Speed
(940 - 772) / 772 = 21/76 $ same answer
