Some of these are thermal and power limits, and if any of these are exceeded, the operating frequency will immediately begin to subside Mac models with Turbo Boost 2020 MacBook Air Retina One thing to keep in mind is that, naturally, these clock speed increases are limited by a number of factors. Look up AppleIntelCPUPowerManagement and then find Turbo Ratios to determine yours. And to do this, you will need to head over to Console, after which you will need to open kernel.log (or in case you are using Mountain Lion, that will be system.log). 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.
