Sapphire Radeon HD 7970 OC 3GB Video Card Review

Unigine Heaven 3.0

The ‘Heaven’ benchmark that uses the Unigine easily shows off the
full potential of DirectX 11 graphics cards. 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 extent and exhibiting the possibilities of
enriching 3D gaming. 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.

For this benchmark we used Heaven DX11 Benchmark Version 3.0, which just came out on March 7th, 2012. We haven’t run this benchmark in over a year, so it will be interesting to see how this new generation of video cards handles this benchmark. We wanted to see how the cards would do with mild settings, so we disabled AA and AF and set the Tessellation to moderate. We ran the benchmark at 2560×1600, 1920×1200 and 1280×1024 to see how the cards would perform with a wide variety of settings.

With moderate tessellation enabled and AA and AF disabled the benchmark results were very close.

Many feel that tessellation is one of the most important features of game titles today and in the future, so we set tessellation to extreme and maxed out the anti-aliasing at 8x and the anisotropic filtering at 16x. These are as high as you can set the tessellation and image quality settings in Heaven DX11 Benchmark v3.0, so it will really punish these cards.

With the tessellation set to extreme and AA cranked up we really stress the cards memory bandwidth! We see a 1-2 FPS difference between the two BIOS modes on the SAPPHIRE HD 7970 OC.
