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