It actually does very little. For those apps that can take advantage of it, it makes the CPU work as though there were two in the system.

hyper threading is developed by intel...

Hyper-Threading Technology enables multi-threaded software applications to execute threads in parallel. This level of threading technology has never been seen before in a general-purpose microprocessor. Internet, e-Business, and enterprise software applications continue to put higher demands on processors. To improve performance in the past, threading was enabled in the software by splitting instructions into multiple streams so that multiple processors could act upon them. Today with Hyper-Threading Technology, processor-level threading can be utilized which offers more efficient use of processor resources for greater parallelism and improved performance on today's multi-threaded software.

To cut the story short if you have 1 processor, enabling the hyperthreading mode can generate 1 logical processor and will cut the software processes in half in information are distributed to the original processor and the logical processor.

Examine your device manager under processor.

hyperthreading off  -- you only have 1 processor

hyperthreading on -- you have 2 processors

but now the most advance technology that intel has is the "dual core processor"
