Sapphire Special Edition HD6970 and HD6950 CFx Multi Screen Review

To overclock the Sapphire cards, we used the Sapphire TRIXX overclocking tool. We use this all the time and it is one of the best pieces of software available for AMD users.

We managed to get the Sapphire HD6970 to 960mhz on the core and 1475mhz on the memory (5900mhz effective) and the Sapphire HD6950 to 850mhz on the core and 1450mhz on the memory (5800mhz effective). Very similar results to the other cards we have tested recently.

The HD6970 overclocked delivers fantastic performance increases with the Unigine Benchmark, actually surpassing the performance of the HD5870's in CFx. This is a good indication of the hardware tessellation improvements we noted earlier in the architectural section of the review.

Temperatures of both cards rose by around 3 C under load when overclocked.
