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:
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.
