Central Processing Unit

1
Central Processing Unit

• The CPU essentially functions as the brain of the
  computer.

2
Manufacturers

• Intel and Advanced Micro Devices (AMD) are the
  two largest manufacturers of CPUs.
• Intel is substantially larger than AMD but they
  both make CPUs found commonly in computer
  systems.

3
Intel

• Intel currently manufactures the fastest CPUs on
  the market and their CPUs are often more
  expensive than those made by AMD.
• Intels CPUs use names such as Pentium, Celeron,
  Core2 Duo, Core 2 Quad, Core i3, Core i5, and
  Core i7.

4
AMD

• AMDs CPUs are found in the same spectrum of
  computers which use Intel CPUs, but they are
  often less expensive.
• AMD CPUs use names such as Sempron, Athlon 64
  X2, Athlon II, Phenom X2, Phenom X4, and Phenom
  II.
• Intel and AMD both develop innovative
  technologies that lead to advancements in the
  field.

5
PGA

• Pin Grid Array CPUs have pins on the CPU that
  plug into a motherboard socket.

6
LGA

• Land Grid Array CPUs have Pins on the
  motherboard and contact points on the CPU.

7
Installation

• Always follow the manufacturers instructions
  when installing CPUs.
• As with other electronic components, always take
  steps to prevent electrostatic discharge (ESD)
  from damaging the CPU and motherboard.
• Antistatic wrist straps and antistatic mats help
  to prevent ESD.

8
Installation Continued

• When applying thermal paste to the CPU, apply it
  evenly across the surface of the CPU.
• Some heatsinks come with thermal paste
  pre-applied. In this situation, do not apply
  additional thermal paste to the CPU.
• Only use heatsinks that are designed to work with
  specific CPUs and socket types.

9
Factors that affect CPU price

• Processor Speed
• CPU Interface (Motherboard Dependent)
• Number of Cores
• Cache
• Bus Speed
• Manufacturer

Which to Purchase?

• Both AMD and Intel make excellent CPUs. Always
  perform research, read reviews, and make your
  decision based on the intended use of the
  computer and the allotted budget.
