A:Answer Greetings from the Intel team. Thank you for your question.
2.4 GHz is the processor base frequency; the Lenovo - Ideapad 3i model 82H80358US comes with the Intel® Core™ i5-1135G7 processor, which is a high-end processor that has a Base Frequency of 2.4 GHz and a Max Turbo Frequency of 4.2 GHz.
CPUs do not always need to run at their maximum frequency. Some programs depend more 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.
