5. Is a processor 32-bit or 64-bit
?
The varients of processors are 32-
bit and 64- bit processors.
The 32-bit processors are initially
used upto 1990’s.
The 64-bit computer has been
around since 1961 when IBM
created the IBM 7030 Stretch
supercomputer.
However, it was not put into use in
home computers until the early
9. Clock Speed
The clock speed of a processor, which
is specified in megahertz (MHz) or
gigahertz (GHz), determines its
performance.
But, only clock speeds are meaningless,
when you specify the
speed of the processor.
10. Examples
A 3.2 GHz Prescott-core Pentium 4 is
about 6.7% faster than a 3.0 GHz
Prescott-core Pentium 4, as the relative
clock speeds would suggest.
However, a 3.0 GHz Celeron processor
is slower than a 2.8 GHz Pentium 4.
11. Host-bus Speed
The host-bus speed, also called
the front-side bus speed, FSB speed, or
simply FSB..
It specifies the data transfer rate
between the processor and the RAM.
A faster host-bus speed is a numerical
value,that contributes to higher
processor performance, even for
processors running at the same clock
12. Cache Size
Processors use different levels of
cache memory to improve
performance by buffering transfers
between the processor and
L1 Cache ( Layer 1) : 2KB-64KB
L2 Cache ( Layer 2) : 256KB-512KB
L3 Cache ( Layer 3) : 1MB-8MB
13. Socket Type
Socket type defines the structure that
the processor resides on it.
For example, if you are replacing the
processor in a Socket 478
motherboard,you must choose a
replacement processor that is designed
to fit that socket.
intel Celeron D, Pentium4
are fit to Socket 478.

15. How many cores a Processor
have?
Single Core
Dual Core
Quad Core
Hexa Core
Octa Core
16. Examples
Single Core :
- AMD Athlon 64 FX-55, intel core Solo,intel Core duo
Dual Core :
- AMD A4-3300,intel i series lower gen Processors
Quad Core :
- AMD ,intel i series advanced Gen.
Hexa Core :
- AMD Phenom,intel Adavanced Gen.
Octa Core :
- Advanced intel Core Processors
18. What is Hyper threading ?
Hyper-threading allows a single physical
core to act as two virtual cores.
Thus it enables performing multiple
tasks simultaneously without activating
the second physical core (which would
require more power from the system).
Example : i7 > i3 > i5
19. What is Turbo Boosting ?
Turbo Boost is Intel’s proprietary
technology to intelligently increase a
processor’s clock speed if the
application demands it.
For example, if you are playing a game
and your system requires some extra
horsepower, Turbo Boost will kick in to
compensate.
Example : i7 > i5
20. What is Cache Size ?
Cache is the processor’s own memory
and acts like its private RAM
Example : i7 > i5 > i3
Processor Model
Cache Size
(Minimum)
Cache Size
(Maximum)
i3 3 MB
i5
3 MB
6 MB
i7 4 MB 8 MB
21. What is GPU ?
GPU stands for Graphics Processing
Unit
Nvidia introduced the first GPU, the
GeForce 256, in 1999 and remains one
of the major players in the market.
The other popular GPU manufacturing
Company is the AMD
23. What is APU ?
APU stands for Accelerating
Processing Unit.
APU Architecture integrates both
CPU and GPU units.
APU is a technology is introduced by
the AMD
Example : AMD Shared
Graphics,Intel Shared Graphics units.
25. Notations
U : Ultra Low Power. The U rating is only for laptop processors.
Y : Low Power. Typically found on older generation laptop and
mobile processors.
T : Power Optimized for desktop processors.
Q : Quad-Core. The Q rating is only for processors with four
physical cores.
H : High-Performance Graphics. The chipset has one of Intel’s
better graphics units in it.
K : Unlocked. This means you can overclock the processor above its
rating.
