You can check the Turbo Ratio that your system is set to on your computer. So If you have a Mac has a clock speed of 1.6 GHz, it may be boosted to a total of up to 1.6 GHz + 900 MHz = 2.5 GHz. Hence, in the above example of a Turbo Ratio of 6589, the clock speed can be increased by a maximum of up to 900 MHz. So, for example, if the Turbo Ratio number is set to 6589, 6 represents the increase when there are 4 cores in operation, 5 – when 3 cores are working, 8 – for 2 cores, and 9 is for when there’s only 1 core in use.Īnd the numbers themselves represent increments of 100 MHz by which the power is boosted. And the way to determine how much extra power you will get for the amount of used cores is by looking at the Turbo Ratio.Įach digit in the Turbo Ratio represents a number of cores, descending from left to right. Turbo boost can be found in all Apple lineup products.ĭepending on the configurations of the specific computer model, the Turbo Boost will be set to increase the clock speed to different amounts, in respect to the number of cores in operation. In turn, this increases the so-called clock speed of the cores that are still in operation, i.e. This happens as a result of the processor’s ability to shut off those of its cores that are currently not in use. This is a trademark Intel technology that serves the purpose of increasing a computer’s performance and it may also reduce its power usage. (four Thunderbolt 3 ports)įor several years now, since 2008 to be precise, Apple has been producing Mac computers with a remarkable feature called Turbo Boost. Lastly, it's worth mentioning here that Turbo Boost Switcher will indeed give your battery life a great boost, which means that the app is a handy little thing to have under your belt if you have a Mac which has gone way above its charge cycles. If it's clearly mentioned in text that it is, then simply download Turbo Boost Switcher and you're golden. Once you've noted that down, simply head over to and see the technical specifications of your Mac to see whether or not Turbo Boost technology is supported. You can do so by clicking on the 'Apple' logo in the OS X Menu bar, then click on 'About this Mac.' The resulting window will show you a bunch of information, with the first line in the 'Overview' tab specifying the model of your Mac. ![]() In order to find out if your Mac supports Turbo Boost or not, first of all find the model of your Mac. Before you install it, make sure that your Mac supports Turbo Boost technology, otherwise the app will be of no use to you. ![]() The little app is called Turbo Boost Switcher, and is absolutely free, and you can grab it from here. Enable / Disable Turbo Boost On Your Mac And Save Battery Life, Keep Things Less Noisy Thankfully, this little app changes all that. This is something which is controlled automatically by OS X, and the user has no control over it at all. If you don't want that sort of thing to happen to you, then there's a small little app which you can download right away to manually disable or enable Turbo Boost technology. When Turbo Boost kicks in, it overclocks the CPU, which in turn heats up your Mac, which, as you might've guessed by now, kicks into action the CPU fan, subsequently making a lot of noise. And down the road, the company has been making great strides when it comes to the processors it has chosen to use with its entire computer lineup, with Turbo Boost being a swift little addition, giving the user a slight boost in speed over the advertised limit so that things are done in a much more efficient manner when the need arises.īut while Turbo Boost is a great little piece of technology to have under the hood of our Macs, it can, at times, become absolutely annoying. Without a doubt, jumping onboard the Intel bandwagon was the best thing Apple pulled off in recent years. ![]() ![]() Here's a complete tutorial how you can disable or enable Turbo Boost on an Intel powered Mac computer.
