This difference has a huge impact on battery life and heat, resulting in a lot more battery life without losing performance.Īs technology evolves, the factory sweet point for the majority of CPUs is more personalized. But it actually runs well at 2 GHz with just 1.0750 V. To give you an idea: my CPU with a nominal frequency of 2 GHz normally runs at 1.2625 V. Close Unnecessary Apps on Mac We often leave the ‘n’ number of apps open on our Mac. Best Tips and Tricks To Speed Up Your Mac 1. However, a few workarounds may help you save your day.

So the ideal voltage will be a little higher than that point. With passing years and new upgrades, Macs tend to slow down irrespective of the model you own or the amount you have spent over them. When you try to run with lower voltage at 2 GHz for example, you will get to a point where your computer will shut down. It's not the same with overclocking or overvolting. It easily undervolts your CPU if you want the frequency. One application that was nice for Mac OS X is CoolBook.

You have to check your particular processor. Some of them are sold as ULV (Ultra Low Voltage CPUs) that are expensive to buy because they have better performance for less wattage and less impact on battery life.

A percentage of them will work well with lower voltage. Normally higher frequencies need higher voltages - more heat is released, the fans have to work and so on.ĬPUs are not the same when they come out of the factory - they all receive voltage that 99% of them work with. It's not the frequency that 'wastes' battery life, but the voltage.

Mac cpu speed is slow
