Sapphire HD 7970 6GB Toxic Edition Review

For our overclocking tests today we are using the latest version of Sapphire's TriXX software. We have always had good experiences with this program.

We weren't expecting to achieve a huge increase on the HD7970 6GB Toxic clock speeds – not with such high pre-configured, overclocked settings. We managed to push the core by another 61mhz to 1,261mhz, translating to a 5% increase. The memory maxed out at 1,708mhz (6832mhz effective).

Increasing board power didn't make a difference … this card is sold close to the limit, with just a little headroom to ensure stability.

The additional increase helps boost the 3dMark 11 score past the 10,000 threshold, scoring 10,226 points. This is the second single GPU card we have tested to score over 10,000 points.
