Windows Subscore for the Asus HD 6670 1 GB video card is. Graphics-7.1 / Gaming Graphics-7.1

Windows Subscore for A8 3870K APU and Asus HD 6670 1 GB video card as Crossfire is. Graphics-7.0/ Gaming Graphics-7.0

I just would like to know why is this? I O.C the APU'S Graphics close to the Asus HD 6670 1 GB video card and i still get the same subscore.

They are both working. I am useing TechPowerUP GPU-Z 0.6.4 to monitor them. I can see the Subscore going up 0.1 or 0.2 but it going down 0.1 is odd.

Its because an APU has to share bandwith with the CPU, witch in turn bottlenecks the GPU on the APU, the only way to reduce that effect is the fastest memory you can find/afford.

please note with APUs RAM speed is much more important than latency, wheres the CPUs like the Core2 And Athlon XP had external memory controllers worked fastest with the lowest latency possible.
