Technology
Intel Hyper-Threading (HT) technology enables the processor to work on two sets of
tasks simultaneously, by using resources that would otherwise be idle. This allows the
user to get more work done in less time. HT offers improved performance and better
responsiveness for today's multitasking workloads. HT enables certain specific
operating systems to see two logical processors where there is only one physical
processor. Since the operating system sees two logical processors, it can schedule
tasks to be processed simultaneously.
Today's applications and operating systems are more feature-rich and power hungry.
IT background services (such as virus scans, email compression and file encryption)
make the computing infrastructure more robust, but add load to the PC processor.
There are two typical approaches to keep systems responsive and users operating at
top efficiency:
increasing clock speeds (MHz) . This increases the number of instructions/second.
HT fully utilizes the processor's current resources and enables the processor to get
more work done on each clock cycle.
The image below highlights the time necessary to complete two tasks with and without
HT and illustrates the benefit of HT:
Customer Benefits of HT Technology:
For IT managers: Keep background services in the background. HT minimizes
productivity impact of virus scanning, encryption, compression, and management
applications
For PC users: Work without waiting. HT increases multitasking efficiency and
enables greater productivity
For the future: HT combined with gigabit ethernet speeds data throughput and
enables faster networking
HT Technology improves performance in today's demanding multitasking
environment—allowing users to get more done in less time.
