Hyper-threading is the concept given by Intel to promote simultaneous multithreading. It increases the throughput of the system drastically. Enables to process series of threads at the same time.Hyper-Threading technology creates two virtual processing cores for each physical core present in a CPU. It increases the efficiency of the system. It increases thread level parallelization.

3. What is a Processor?
O A processor is the logic circuitry that
responds to and processes the
basic instructions that drive a computer.

4. Manufacturers
O Intel
O AMD
O NVIDIA
O Qualcomm
O Cyrics
O Atmel

5. Overview of Intel
O Intel Corporation is an
American multinational
corporation and technology company.
O Headquartered in Santa Clara, California.
O Founded by Gordon Moore and Robert
Noyce.

6. Introduction to hyper-
threading
O Allows processor to work more efficiently.
O Enables the processor to execute series of
instructions or threads at the same time.
O Provides two logical processor in a single
logical processor
O Is a technique used to improve parallelization
of computations performed on PC
microprocessor.

7. (Conti.)
O technique which enables single CPU to act like
multiple CPU’s.
O Enables different parts of the CPU to work on
different tasks concurrently.
O Threaded software application to execute threads
in parallel in a single multi-core processor instead
of thread processing in linear fashion.
O First used in Intel Xeon microprocessor .

Multi-Core Processors
Hyper-Threading Concept (Virtual cores)

13. Difference Between
Multi-Core and Hyper-
threading
O Hyper-Threading Technology
Hyper-Threading technology creates
two virtual processing cores for each
physical core present in a CPU.
O Multi-Core Technology
Multi-core technology, which is most
commonly available in dual-core, quad-
core and hexa-core CPUs, is a
technology that adds extra physical
processing cores.

15. Business Benefits of H-T
Technology
O Higher transaction rates for e-Businesses.
O Improved reaction and response times for
end-users and customers.
O Increased number of users that a server
system can support.
O Handle increased server workloads.

16. Bar graph showing improved throughput of the
processor by hyper-threading

17. Current Processor
Technology
O Intel has recently released its COREi9 x-
series which can have upto 10 cores.
O It is working on COREi9 extremes which
can have upto 18 cores .

18. Conclusion
O Intel has basically derived this concept for
allowing Megatasking.
O Increases the efficiency of the system.
O Intel’s Hyper-Threading Technology brings the
concept of simultaneous multi-threading.
O No performance loss if only one thread is
active.
O Increased performance with multiple threads
O Increase thread-level parallelism
