HIS HD6990 Dual CrossfireX Review

Unigine provides an interesting way to test hardware. It can be easily adapted to various projects due to its elaborated software design and flexible toolset. A lot of their customers claim that they have never seen such extremely-effective code, which is so easy to understand.

Heaven Benchmark is a DirectX 11 GPU benchmark based on advanced Unigine engine from Unigine Corp. It reveals the enchanting magic of floating islands with a tiny village hidden in the cloudy skies. Interactive mode provides emerging experience of exploring the intricate world of steampunk.

Efficient and well-architected framework makes Unigine highly scalable:

  • Multiple API (DirectX 9 / DirectX 10 / DirectX 11 / OpenGL) render
  • Cross-platform: MS Windows (XP, Vista, Windows 7) / Linux
  • Full support of 32bit and 64bit systems
  • Multicore CPU support
  • Little / big endian support (ready for game consoles)
  • Powerful C++ API
  • Comprehensive performance profiling system
  • Flexible XML-based data structures

We test at 1080p so that all video cards can be compared throughout our reviews. Obviously driver updates might enhance performance slightly over time, but as a rule, its a useful way for us to present the findings.

The Unigine Heaven performance with two HD6990's is staggering, averaging over 144 frames per second. We did get a re-occuring glitch from time to time which would force the frame rates into single digits, just for a split second but enough to register with the benchmarking tool. Driver updates should sort this out.

  1. lol, bet you wish they could run in a 3x 6x setup !

  2. 14,000 in 3dmark 11. I thought i was doing well, breaking 5k last week 🙁 I suck.

  3. Wow. just wow. AMD are owning everyone this week……..

  4. YAY! 48k in vantage. insane, this card just friggin rocks.

  5. I wouldnt be getting all too excited just yet, Nvidia have yet to unleash the GTX590 which I would think might kick the 6990’s arse.

  6. The nvidia architecture is slightly more powerful overall, but its all about temperatures, otherwise they would both slap three cores on a PCB and duke it out. its not quite that simple.

    its actually a feat of engineering in itself that AMD got this crappy single fan to cool such a powerful card. I almost choked on my cornflakes when I saw that tiny red fan, used YET again.

  7. Man I’d love four screens and two of these. Best start saving.

    Oh yeah and a new psu

    And a new CPU

    Damn…..

  8. Crazy frame rates, do we really need kind of power? Best game in months was dead space 2 and it could run well with a 6850.

    Portal 2 should be the same….

  9. Hey quick question. Whats this sticker over the bios switch, do you void warranty by running the card at full speed? Is it dangerous? I really really don’t get this…

  10. hell when you limit an overclocked 12 core intel processor at 2560 then you know you have something special !

  11. One thing is certain, you wont be running this setup on a 650W psu. I think a 1200w is a minimum for this setup. might get away with 1000w, but it would be rather highly loaded with the rest of the components in the mix.

  12. That performance is just stupid. as in stupid good, not stupid sucky.
