What is Hyper-Threading?
utilization of processor execution resources. As a result, an average improvement of ~40% in CPU resource utilization yields higher
processing throughput.
How Hyper-Threading Works
A form of simultaneous multi-threading technology (SMT), Hyper-Threading technology allows multiple threads of software applications to

Hyper-Threading technology is an innovative design from Intel that enables multi-threaded
software applications to process threads in parallel within each processor resulting in increased

Intel Hyper-Threading technology based processor.
You can see that the architectural state for each
processor is duplicated, while the execution
resources is shared.
