The cards will be tested using our usual X58 system which has the following specifications:
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.
|Cards||Core Clock Speed||Memory Clock Speed|
|HIS 6850 IceQ X Turbo||820MHz||4400MHz DDR|
|MSI R6850 Cyclone II Power Edition OC||860MHz||4400MHz DDR|
|Sapphire Radeon HD 6850 Toxic Edition||820MHz||4400MHz DDR|
|Reference / Gigabyte Radeon HD 6850 1GB||775MHz||4000MHz DDR|
