• Multi-core processors represent a major evolution in
• They are several mostly independent cores which
work together in parallel
•performance and productivity benefits beyond the
capabilities of today’s single-core processors.
•A multi-core microprocessor is one which combines two
or more independent processors into a single package,
often a single integrated circuit.

What do you mean by Multi core?
If multi means two or more, what types are there?
•The first commercial dual core processor was IBM's
Power 4 processor for it's RISC servers in 2001.
•The first dual core processor for home use was
Intel's Pentium Processor Extreme Edition 840,
released in early April 2005.
•Less than two weeks later AMD brought their
Opteron 800 Series and Athlon 64 X2 processors to
• it will work faster for certain programs
•Cool and quiet
•The signals between different CPUs travel shorter
•They do not work at twice the speed as a normal
processor. They get only 60-80% more speed.
•The speed that the computer works at depends on
what the user is doing with it.
•They cost more than single core processors.
•They are more difficult to manage thermally than
lower-density single-core processors.
• Video editing
• Encoding .
• 3D gaming.
• Powerful graphics solution
• Optimized productivity titles, such as AVG's
Next-generation software applications will
require the performance capacity provided by
multi-core processors. Software destined to
break barriers in the user experience, like as
• Voice recognition
• Artificial intelligence (AI)
That will be only possible by multi-core processors
