Intel Hyper-Threading Technology can be defined as “Hyper-Threading Technology (HT Technology) is a ground breaking technology that boosts computing performance to keep pace with today's applications and operating systems. HT Technology enables a single processor to function as two "virtual" processors by executing two threads in parallel, allowing you and your software to multi-task more effectively than ever before”.
Intel has introduced Hyper Threading technology for pentium 4 processors.
Hyper-Threading (HT) Technology is available on notebook, desktop, server, and workstation systems. Hyper-Threading Technology requires a computer system with an Intel® Pentium® 4 processor supporting Hyper-Threading Technology and an HT Technology enabled chipset, BIOS and operating system. Performance will vary depending on the specific hardware and software you use.
Here is a list of Intel Pentium 4 processors that support hyper threading technology.
For Hyper-Threading technology to work, you should have the Intel processor, Intel chipset (motherboard) BIOS configuration enabled, and an OS that is optimized for the HT technology.
