Module 2/ Unit 4
Processors
Objectives
On completion of this unit, you will be able to:
-Differentiate Intel and AMD CPU models.
-Understand technologies for improving performance, such as architecture,
multitasking, multiprocessing, multi-core, and cache.
-Describe other CPU features such as clock speed, overclocking, power
management, and VT.
-Describe characteristics and CPU compatibility of processor sockets.
-Identify the components used for cooling(heat sinks and fans and liquid
cooling systems).
Central Processing Unit (CPU)
The Central Processing Unit (CPU or simply "the processor") executes program instruction code,
performs mathematical and logical calculations, and controls Input / Output (I/O) functions.
The CPU is commonly described as the "brains" of a computer; in fact, it is better thought of as
a very efficient sorting office. The CPU cannot think, but it can process simple instruction very,
very quickly and efficiently. A computer is only as "clever" as its software.
PC processors are produced by Intel or other manufacturers who uses the Intel instruction set and
whose processors are therefore IBM PC (or X86 ) compatible. Currently only AMD (Advanced Micro Devices)
fall into this category.
Overview of CPUs
There have been numerous CPU architectures and within each architecture a number of different model
and for each set of models a brand to position them within a particular market segment. The following list is
designed to give to you a brief overview of the main ranges produced by Intel and AMD.
