AMD’s Trinity APUs have only been in the press a little while, but some are already pushing the new desktop silicon to its limits.  By giving the A10-5800K model 1.956 volts, disabling two of its cores and cooling it with liquid nitrogen, overclockers were able to push the chip to 7.3GHz.  Air-cooling and 1.616 volts squeezed out 5.1GHz without sacrificing any cores.   Normal users can improve CPU performance by roughly 10 percent and GPU speeds by 15 to 17 percent.
