These represent boosts of 13 and 14 percent respectively, so both cards appear to overclock to similar levels. These efforts were rewarded by healthy gains in both Battlefield 3 and Crysis 3 that put the card almost (but not quite) on par with the Radeon HD 7850 2GB.Īs for the R9 270X 2GB, we settled on clock speeds of 1.19GHz for the core and 1.6GHz (6.4GHz effective) for the memory. This is pretty impressive when you consider that the card's memory chips are not actively cooled either. Meanwhile, we got the memory all the way up to a mighty 1.8GHz (7.2GHz effective), which is not only an 11 percent boost but the maximum clock that the software would allow us to use by default. Nevertheless, we maxed out the power limit to 120% in both cases and got cracking.įor the R7 260X 2GB, we were able to increase the core clock speed from 1.1GHz to 1.24GHz, an improvement of around 13 percent. The first thing we noticed was that neither card could have its voltage adjusted, even when telling the software to unlock it. However, for the R9 270X 2GB and R7 260X 2GB, we fired up MSI's Afterburner software to see how far we could push them.
