If you’re wondering how to enable Turbo Boost, don’t worry - it’s enabled by default. This can increase performance in both single-threaded and multithreaded applications (programs that utilize several processor cores). Intel® Turbo Boost Technology can potentially increase CPU speeds up to the Max Turbo Frequency while staying within safe temperature and power limits. This is sometimes called “algorithmic overclocking”.
But when more speed is needed, Intel® Turbo Boost Technology dynamically increases the clock rate to compensate. Running at a lower clock rate (the number of cycles executed by the processor every second) allows the processor to use less power, which can reduce heat and positively impact battery life in laptops. Intel® Turbo Boost Technology is an energy-efficient solution to this imbalance: it lets the CPU run at its base clock speed when handling light workloads, then jump to a higher clock speed for heavy workloads. Some programs are more dependent on memory to run smoothly, while others are CPU-intensive. Note: Intel Turbo Boost Technology 2.0 allows the processor to operate at a power level that is higher than its rated upper power limit (TDP) for short durations to maximize performance.How Does Intel® Turbo Boost Technology Work?ĬPUs don’t always need to run at their maximum frequency. Intel Turbo Boost Technology 2.0 has multiple algorithms operating in parallel to manage current, power, and temperature to maximize performance and energy efficiency. When the processor is operating below these limits and the user's workload demands additional performance, the processor frequency will dynamically increase until the upper limit of frequency is reached. The amount of time the processor spends in the Intel Turbo Boost Technology 2.0 state depends on the workload and operating environment.Īny of the following can set the upper limit of Intel Turbo Boost Technology 2.0 on a given workload: The maximum frequency of Intel Turbo Boost Technology 2.0 is dependent on the number of active cores. Apple 12-inch MacBook - Gold/1.4GHz Intel Dual-Core Core i7, Turbo Boost up to 3. Intel Turbo Boost Technology 2.0 is activated when the Operating System (OS) requests the highest processor performance state (P0). By default the processor runs at 2.3Ghz, and when under heavy load, it will automatically speed up the cores up to 3.3Ghz. This increases performance (the cores that are being used get faster) and can reduce power usage.

The Mac I'm on now (a 2.0 GHz Core i7 MacBook Pro), for example, has Turbo Ratios set to 6689 for a maximum clock of 2.9 GHz when using only one core. What does turbo boost up to 3.6 Ghz mean Turbo Boost is a feature that, when fewer than the total number of cores are being used, the processor can turn off the unused cores and increase the clock speed on the rest of the cores. To see what your system is set to, go to Console and open the kernel.log (or system.log in Mountain Lion*), then search for AppleIntelCPUPowerManagement and look for "Turbo Ratios". The number specifies the boost in 100 MHz increments above the listed clock speed, so if two cores are running, they can be boosted to 1.6 GHz + 400 MHz = 2.0 GHz and if one core is running, it can be boosted to 1.6 GHz + 700 MHz = 2.3 GHz. The number sets the amount of boost by digit (4 cores = 0, 3 cores = 0, 2 cores = 4, 1 core = 7 this is a dual-core CPU, so 3- and 4-core mode is irrelevant). This increases performance (the cores that are being used get faster) and can reduce power usage.įor instance, if you have the 2011 MacBook Air with the 1.6 GHz Core i5 (as detailed in this AnandTech article), the "Turbo Ratio" is set to 0047. Turbo Boost is a feature that, when fewer than the total number of cores are being used, the processor can turn off the unused cores and increase the clock speed on the rest of the cores.
