F1 2010, Temperatures and Power Usage
Ultra settings and 4x AA, we can see that the 6850 is 1 FPS slower than the 6870.
The 6870 is advertised to run at 150W TDP and the 6850 at 127W TDP. So logically the 6870 should run hotter than the 6850 which it does, we recorded a 2 degree celsius difference on the cards under full load.
The 6870 uses a tad more watts with our system compared to the 6850.
