PowerColor HD6970 Devil 13 2GB Review

For overclocking today we used the excellent Sapphire TriXX software tool, which we use for all our AMD based discrete reviews.

Using TriXX we managed to increase the voltage to a stable level, while increasing the core clock to 1000mhz – any higher than this and the system would become unstable. The card has certainly been released in a highly overclocked state, so we weren't expecting a dramatic increase on either core or memory speeds. The GDDR5 memory doesn't have a lot of headroom (2.5%), only 35mhz extra was possible before artifacting would occur.

The increase is small, but noticeable. around 200 points extra in the Direct X 11 based 3DMark 11.
