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"

Follow these steps, to verify Hyper-Threading Technology is enabled in Windows XP Task Manager:
  1. Right click Task Bar
  2. Click Task Manager
  3. Click the Performance tab
Verifying Hyper-Threading Technology in Windows* XP Task Manager
The Graph that is circled should be separated in the middle like this one. There is an increase in system performance with Hyper-Threading enabled. I ran a test. I disabled Hyper-Threading in the BIOS. Then I went to the Task Manager under performance and launched different programs. I noticed  that when I launch Windows Media Player 10 for example, the CPU usage shot up to almost 100%. Then I enabled Hyper-Threading, and noticed a decrease in CPU usage when launching programs. Media Player 10 only used 40% CPU usage when launched, other programs as well used less CPU usage.
