XFX HD6850 Dual Fan CFx review – ultimate gaming for £300 ?

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.

Compared with the last generation, the AMD graphics hardware has improved significantly. The HD6850's in Crossfire score an average frame rate of over 50 fps, falling around half a frame behind the GTX570.

  1. Christ thats a lot of work. those cards are brilliant for 145. great for a future upgrade if you bought one now.

  2. fucking A1 man. great work

  3. Very very very very nice. I like the cooler design from XFX. these guys are delivering

  4. Lovely. liked the videos too. I must get that battlefield game, keep meaning to.

  5. great design from XFX< especially the power drain and noise. excellent

    Also, have to hand it to you, quality of reviews this week has been top drawer.

  6. A good point was made on the crossfire driver profiles. are they any faster out of the drawer with them now ? they seemed to be slow in the past.

  7. nice performance, but im saving for a 6990. if its good, It better be.

  8. Keep em coming, but I too am waiting on 6990 review next year. im all set for reading. you got one already Zardon?

  9. Read this over a cup of tea. what a great article and i liked the rating system, its hard to work out later what did what and what is performing better in which engnie.

    HAWX2 seems like a total farce to me.

  10. Wicked. The prices of all these cards now are great. still got my GTX460 and love it, no need to move, but ive my eyes on the GTX580, if I ever get the money.

  11. Hunting for my mojo

    Am I the only one who finds the new AMD range a little underwhelming? id expected the HD6900 series to do more. these are good cards though for the money.

  12. I am ordering these for my son for his birthday in January. if I order now I might get them in time, due to the crap weather here 🙁

  13. Hard to beat this at the price, I’m sold

  14. Excellent idea. Unfortuantely AMD can be slow with profiles for CFX sometimes so performance would be much worse

  15. Good detail, 6850s are good value cards, I like this design from xfx

  16. Shame scan won’t deliver before Christmas because of our shitty weather. 🙁

  17. I’ve no idea why AMD and XFX are selling 6850s with such low core clocks, they have huge headroom.

  18. Ordering anything in the UK now is a waste of time, but this card is worth 144 quid ! will wait till new year before deciding anything, but its one of the top 3 choices for me. (not ordering two though, ive only one screen).

  19. nothing to say, but well done. liked the article.

  20. Excellent editorial piece from KG. cards are very good, I already have a powercolour HD5850, but I might upgrade next year to a 6950. Crossfire is great in principle, but I had issues with a older cfx setup. never again.
