Overclocked AMD Radeon HD 6850 Duel - HIS vs. MSI

Overclocked AMD Radeon HD 6850 Duel - HIS vs. MSI



Test Setup & Results

Test Setup

The cards will be tested using our usual X58 system which has the following specifications:

  • Intel Core i7-975 (3.33GHz)
  • Gigabyte GA-EX58-UD4P motherboard
  • 3 x 1GB DDR3-1333 G.Skill memory in triple channel mode
  • Seagate 7200.10 200GB SATA hard drive
  • Windows 7 Ultimate

Clock speeds are a good indication of a card’s performance and based on pure clock speeds alone, we are expecting the MSI R6850 Cyclone II Power Edition OC to be the faster card. Raw graphics performance aside, we are also interested to find out how effective their custom coolers are and also how much overclocking potential they have. To keep things interesting, we have also presented results of the Sapphire Radeon HD 6850 Toxic Edition, which was the winner of Best Mainstream AMD Graphics Card in our Tech Awards 2011.

If you have already forgotten, here's a summary of the cards' clock speeds.
