Hyper Threading Technology
Introduction
• Hyper-threading is a technology developed by
Intel Corporation for it’s Xeon processors with
a 533 MHz system. It was released in March 2002.
• Hyper-threading technology, commonly referred to
as "HT Technology," enables the processor to
execute two threads, or sets of instructions, at the
same time.
• HT Technology converts a single physical
processor into two virtual processors.
• HT Technology is also present in all Pentium
4 processors with 800MHz CPU bus speed
(2.4 GHz up through 3.8 GHz) as well as
the Pentium 4 Extreme Edition and the
Dual-core Pentium Extreme Edition.

Dual Core Technology
Introduction
• In a Dual core processor each core handles
incoming data strings simultaneously to
improve efficiency.
• When one is executing the other can be
accessing the system bus or executing its own
code.
• To utilize a dual core processor, the operating
system must have simultaneous multi-
threading technology.
• Intel introduced the first dual core processors
(the Pentium D and Pentium Extreme
Edition).
