Intel turbo boost的中文翻译为”睿频加速”，一般情况下turbo(睿频)指的就是Intel turbo boost。本文将记录turbo相关notes。

CPUs don’t always need to run at their maximum frequency. Some programs are more dependent on memory to run smoothly, while others are CPU-intensive. 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.

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. But when more speed is needed, Intel Turbo Boost Technology dynamically increases the clock rate to compensate.

Intel Turbo Boost Technology can potentially increase CPU speeds up to the Max Turbo Frequency while staying within safe temperature and power limits. This can increase performance in both single-threaded and multithreaded applications (programs that utilize several processor cores).
