For multiprocessor-capable software 
applications, the Hyper-Threading 
based processor is considered two 
separate logical processors on which 
the software applications can run 
without modification. Also, each logical 
processor responds to interrupts 
independently. The first logical 
processor can track one software 
thread, while the second logical 
processor tracks another software 
thread simultaneously. Because the 
two threads share the same execution 
resources, the second thread can use 
resources that would be otherwise idle 
if only one thread was executing. This 
results in an increased utilization of the 
execution resources within each 
physical processor.

The figure below represents how Hyper-Threading saves time when it works. With two logical processors available on every single physical 
processor, multi-threaded applications can now take advantage of thread-level parallelism on each physical processor for additional 
performance. As software applications continue to be optimized to take greater advantage of processor parallelism, Hyper-Threading 
technology provides an additional boost for newer capabilities and the growing needs of today’s users.
