What is throttling in laptops?
Throttling in laptops refers to the intentional reduction of a device’s performance, particularly its CPU or GPU speed, to prevent overheating and improve power efficiency. This process is triggered when the hardware components reach a certain temperature threshold that may lead to damage if not controlled. Therefore, throttling acts as a protective measure to ensure the longevity of laptop components while balancing performance and thermal management.
When a laptop experiences throttling, users may notice a decrease in performance during demanding tasks, such as gaming or video editing. This reduction in speed can lead to slower processing times and lag, reminding users that the system is prioritizing health over performance. Throttling can be a normal part of a device’s operation, especially under heavy workloads.
What causes throttling in laptops?
Throttling is primarily caused by high temperatures in the laptop’s CPU or GPU. When hardware components operate under a heavy load, they generate significant heat.
