Hyperthreading is a technology that allows a single physical CPU core to behave like two logical cores. This can improve performance for applications that can take advantage of multi-threading, such as video editing and 3D rendering. There are a few different ways to check if your computer supports hyperthreading.
One way to check for hyperthreading is to use the Task Manager. Open the Task Manager and click on the “Performance” tab. Under the “CPU” section, you will see a list of your computer’s CPU cores. If hyperthreading is enabled, you will see twice as many cores as you have physical cores. For example, if you have a quad-core CPU, you will see eight cores in the Task Manager.
Another way to check for hyperthreading is to use the System Information tool. Open the System Information tool and click on the “System Summary” section. Under the “Processor” section, you will see a list of your computer’s CPU cores. If hyperthreading is enabled, you will see twice as many cores as you have physical cores. For example, if you have a quad-core CPU, you will see eight cores in the System Information tool.
