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 applications to
be run simultaneously on one processor by duplicating the architectural state on each processor while the same processor execution
