In particularly extreme cases, it may even cause a crash.įor gaming, it depends on how much of your GPU is being utilized. When you begin thermal throttling, what happens will depend on what your GPU is being used for.įor professional rendering, thermal throttling may introduce stutters to your editing process, increase your render times, or both. The specific range of tolerance before thermal throttling will change on a card-to-card basis. Laptop GPUs can’t be made with these same high tolerances though, so you’re most likely already throttling in the mid-70s to mid-80s range. Your graphics card, or GPU, will thermal throttle once it reaches a high enough temperature.įor desktop GPUs, this tends to start no lower than 90☌, and some GPUs are even rated to run at up to 95☌ before needing to throttle. How Your GPU Is Impacted By Thermal Throttling Now, let’s dive deeper into how it works. So, thermal throttling reduces performance once a CPU or GPU decides that it’s getting too hot (risking permanent damage) and needs to slow down. The exact threshold depends on your device, but the point is that it will be a high threshold that you want to avoid. This usually starts happening around 90 degrees Celsius for a given device, but some may not throttle until slightly later or slightly earlier. Thermal throttling refers to a CPU or GPU “ throttling”, or reducing its frequency and therefore performance, once a particular thermal threshold, or temperature, has been reached. Thermal Throttling – What It Is & How It Worksįirst, let’s just define thermal throttling. Today, I’m going to walk you through everything you need to know about thermal throttling, including how to prevent and alleviate the problem. Thermal throttling can plague almost any PC or smart device, but what is it, and how does it actually work?
