HIS 6870 IceQX TurboX - Silent and the most powerful 6870 out there

IceQ X Turbo X may sound like someone thought HD6870 sounded too short, but actually the naming makes sense. The IceQ X means the card is fitted with the custom designed heatsink, and HIS uses "Turbo" to mark the factory overclocked cards and "Turbo X" for the cards with even higher clock speeds. Being in the Turbo X-series of cards, the HD6870 comes clocked at rather impressive 975 MHz on the core and 1150 MHz for the memories. The stock speeds for a HD6870 are 900 and 1050 and the factory overclocks are in fact higher than we managed to clock the stock HD6870.

Despite the high factory clock speeds, we still tried to push the clocks even higher up. Anyway while some tests ran smoothly even at 1040/1200 MHz speeds, these proved unstable in other tests. Finally the stable clockspeeds were so low there would not have been a measurable difference in the performance. The clock speeds are so high out of the box there just isn't any further headroom.



  • Processor: Intel i7 870 (@4022 MHz)
  • Motherboard: MSI P55-GD80
  • Memory: G.Skill Ripjaws 2*2 GB DDR3 2000 CL9
  • Hard drive: Seagate 7200.10 250 GB
  • Power supply: Xigmatek NRP-HC1201
  • Case: Open air test bench

For performance testing we used the same setup as always. In the last two Barts-reviews we haven't had the results by any current Nvidia cards, but now this has changed as we're also working on a GTX 560 Ti review. Not only that, but there's finally also results available for the HD6950, which is the next step up from the HD6870.


3DMark Vantage

Starting off with the Vantage Performance preset. Straight from the first test it's obvious that the high clock speeds of the Turbo X are going to make a difference, the gap between it and the stock speed HD6870 is 5% and the Turbo X actually scores very close to the GTX560.

In the more demanding High-run the difference between the HD6870's remains at about 6%. The last generation flagship HD5870 does really well in the synthetic 3Dmark tests.
