Is hyperthreading enabled by default?
It’s enabled by default, but it can be switched on and off from the BIOS environment by setting “Hyper-Threading Technology” to “Enable” or “Disable”. Note that Intel® Hyper-Threading Technology is only available on some enthusiast CPUs: see the full list here.
How do I know if hyperthreading is enabled?
Run it with -t processor , and compare “Core Count” and “Thread Count” in the output. If these two counts are the same, it means Hyper-Threading is not enabled. If “Thread Count” is twice of “Core Count”, it means Hyper-Threading is enabled.
Should I enable hyperthreading?
If your computer is dual-core, hyperthreading will trick programs to think the CPU is quad-core. That means your CPU-intensive programs and applications will run faster because it reduces execution time. This improved performance means you can run multiple demanding programs at the same time without burdening your CPU.
Can hyperthreading be disabled?
When you get to the Processor menu, select Properties. In most cases, a dialogue box will appear, allowing you to choose to turn hyperthreading off (or on). After you disable the feature, go to the Exit menu and select Exit Saving Changes. The name or layout may differ on your computer.

If the number of logical processors is greater than physical processors (cores), then hyperthreading is enabled.

Do AMD processors have hyperthreading?
Hyper-threading is an Intel technology and AMD processors don’t support it. Neither of them. Although Ryzen chips support “Simultaneous Multi-Threading”, which is similar to Intel’s Hyper-Threading tech. This allows for better distribution and handling of multiple tasks.
Is hyper threading a security risk?
Intel processors are vulnerable to exploitation if they are running hyper-threading, and if you want full security for your CPU, you should disable that feature (which will obviously come at a considerable performance hit in some cases).
