I might figure out this problem
@xcyper33 has the same speed as @rpglord , that mean @xcyper33's CPU is not at 4.5GHz when Dolphin is running (might be at 3.1GHz or sth)

You can go to bios and disable "Intel Speed Step" or force maximum CPU speed / multiplier via ThrotleStop to make sure your CPU is at 4.5GHz all the time
