Sapphire HD6870 Dual Fan Overclock Edition Review (with Dirt 3)

Today we are using the latest version of Sapphires excellent TriXX overclocking tool.

Giving the card a little extra voltage, helped to achieve a 1000mhz final core figure, or an overclock of 80mhz. This is a very impressive increase of almost 9% on a core which is already overclocked. The memory overclocked to 1129mhz, any higher and we started to get random graphic corruption.

The overclock added almost 400 extra points in 3DMark 11, a considerable performance boost. Unigine Heaven frame rates increased by 2.5, placing the card above the reference HD5870 in both tests.

  1. Tres bien ! very nice design. More cards should use bigger (and more) fans.

  2. Great card, if they could get it out for £150 A lot of people would jump all over it.

  3. Dual fan cards rock. AMD always stick with those shitty little 60mm red fans. must be a stockpile in a warehouse somewhere of 10 billion.

  4. Been buying Sapphire for 10 years now, it aint gonna change anytime soon 😉

  5. Can it be bought anywhere yet?

  6. Looks much better than the reference design. 1000mhz core is great. I recently bought a new 24 inch screen and my 6770 runs out of steam with some games, might ebay it and go for one of these if the price is right.

  7. Two of these in crossfire for under 300? you should follow up. I bet it would kick the GTX580 ass.

  8. @Optix,
    by us in the Netherlands, we can get this card for a minimum of £146 (€170) and for a average of £154 (€180) (with the current exchange rates!!)

    €1 ≈ £0,85
