DX11: Unigine Heaven 2.1

The Unigine Heaven 2.1 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.

Although Heaven-2.1 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.

Long ago I came to the realization that as I continued to build, re-build, and enjoy computers as a hobby, as well as for work, that one constant would be in play: continuous performance improvements. This is just another of those "wow" products. There've been many, but this kinda stands out in it's own way. 6990. Can't wait for the 18125's. Hope I'm around that long.

At the rate we're seeing overlapping improvements we'll see something twice as fast in less than two years.

I just ordered mine on the Egg about 3 minutes ago. I'll make my own personal comments after giving it a whirl in my personal world. I might be eating my words from previous posted comments, lol, oh well, as life goes.

# 256bit?zac 2011-03-17 21:25
Is this 256bit? Or 256x2bit?
And if it is only 256-bit video frame buffer, why? Or how? previously all dual gpu setups had 2x the memory controller.

Like the I explain in the article, this product has two GPUs on one PCB. Each GPU offers a 256-bit memory bus to the video frame buffer. Having two GPUs won't make single 512-bit lane, but will double bandwidth to 2x 256-bit.

# AMD 6990 reviewsJ.King 2011-06-27 22:03
Correct me if I'm wrong but as far as I can tell ALL the 6990's are made in exactly the same place. IE the card's are all identical except for the stickers on the front. So why the price difference? This was true for the 6950's and 6970's until recently when a bait and switch was pulled by various manufacturers XFX comes to mind. The card's were changed (BIOS switch was removed and other less obvious changes) but the model number's remained the same and they were still being sold as reference.

You are mostly correct. There are some differences depending on what the partner pays for (cooling/BIOS/overclock), but the engineering is generally all done by the manufacturer. There are a few who receive the engineering and make their own PCB, but it's rare. As for pricing, you'll have to take that up with the brands and retailers.
