hyper threading (HT) technology

Hyper-Threading Technology
Enterprise, e-Business, and gaming 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. Hyper-Threading Technology (HT Technology)† provides thread-level parallelism on each processor, resulting in more efficient use of processor resources, higher processing throughput, and improved performance on today's multithreaded software. The combination of an Intel® processor and chipset that support HT Technology, an operating system that includes optimizations for HT Technology, and a BIOS that supports HT Technology and has it enabled, delivers increased system performance and responsiveness.

Hyper-Threading Technology for Business Desktop PCs
HT Technology helps desktop users get more performance out of existing software in multitasking environments. Many applications are already multithreaded and will automatically benefit from this technology. Business users can run demanding desktop applications simultaneously while maintaining system responsiveness. IT departments can deploy desktop background services that make their environments more secure, efficient and manageable, while minimizing the impact on end-user productivity and providing headroom for future business growth and new solution capabilities.

Hyper-Threading Technology for Gaming and Video
The Intel® Pentium® processor Extreme Edition combines HT Technology with dual-core processing to give people PCs capable of handling four software threads. HT Technology enables gaming enthusiasts to play the latest titles and experience ultra realistic effects and game play. And multimedia enthusiasts can create, edit, and encode graphically intensive files while running a virus scan in the background.

Hyper-Threading Technology for Servers
With HT Technology, multithreaded server software applications can execute threads in parallel within each processor in a server platform. Select products from the Intel® Xeon® processor family use HT Technology to increase compute power and throughput for today's Web-based and enterprise server applications.

Hyper-Threading Technology Benefits for Enterpriseand e-Business
Enables more user support, improving business productivity.
Provides faster response times for Internet and e-Business applications, enhancing customer experiences.
Increases the number of transactions that can be processed.
Allows compatibility with existing IA-32 applications and operating systems.
Handles larger workloads.
† Hyper-Threading Technology (HT Technology) requires a computer system with an Intel® Processor supporting HT Technology and an HT Technology enabled chipset, BIOS, and operating system.

intinya, 1 prosesor fisik intel HT akan dikenali sbg 2 prosesor oleh operating system (baik windows maupun linux). jadi 1 prosesor fisik dikenali sebagai 2 prosesor logical. dengan demikian kinerja cpu dengan prosesor HT akan lebih menakjubkan dibanding dgn cpu berprosesor konvensional.

sebagai contoh: jika anda suka main games atau hobi video editing, maka kinerja software video editing anda tdk akan terpengaruh meskipun anda juga (saat yg bersamaan) menjalankan scan virus misalnya, atau menjalankan SETI@home :D atau lain-lain proses background.

untuk linux anda bisa mengetikkan command grepdmesg processor utk mengetahui apakan cpu anda mempunyai duaprosesor atau lebih. di windows anda bisa cek di device manager - computer - processor.jangan lupa utk mengaktifkan (enable) HT support pada setup BIOS mainboard anda.
