Overclocking
Sapphire provides Trixx Tweak Utility which is really helpfull in setting higher clocks or changing fan speed profiles.
We can see that after overclocking, idle temperature isn’t passing 40 degrees. Under load we can expect to be no more than 70 degrees what is pretty good result considering that fan isn’t loud and most users will be satisfied with its culture of work.
The only thing that is missing in TriXX is core voltage adjustment what is limiting overclocking. Even though we can’t change voltage, card is still overclocking good what we can find out in below tests.
3DMark Vantage
Maximum stable clocks after overclocking were 1220MHz for core and 1750MHz for memory. Probably core clock can run at higher frequency if we set higher voltage but this option wan’t available in Sapphire software.
3DMark 2013 : Fire Strike
Similar to 3DMark Vantage also in Fire Strike maximum clocks that were passing test everytime were 1220MHz for core and 1750MHz for memory. Overall it’s good result.
Overclocking let us achieve about 20% better results and all that without raising voltage.
