All CPUs Apple uses from Intel have TurboBoost support. The speed depends on the actual CPU model in the computer, but an estimate of around 10% will be close. It will not come into play until the CPU is sufficiently stressed to require it or if you find software that can enable it. As far as I know that doesn't really exist as a separate utility. If you were hoping you could turn it on or off at will to increase the average speed of the CPU, then that isn't going to happen. If you want a faster processor then you have to overclock it, and Apple does not permit you access to the BIOS in order to do that; assuming the CPU model permits overclocking.
If you want "faster" then you need to get a computer with a faster CPU.
