THE CENTRAL PROCESSING UNIT
The central processing unit (CPU) is the heart of
the computer. When
selecting the computer CPU you must consider its speed, the socket
style, and
the bus (FSB) speed, the number of processors on board, the power
requirements, cache size, and owner reviews. Of course all of this must
be weighed against the price. The throughput of the microprocessor is a
function
of CPU speed, the FSB speed, cache size, and the number of processors
on board. Each of these items reflects on how much information is
handled in a fixed period of time (throughput). The greater the
throughput, the more you will have to pay. Also prices fall as newer
CPU's replace older models.
The CPU speed is the internal
speed of the CPU, measured in gigahertz (GHz).
The FSB speed is the maximum
speed that the CPU can
communicate with the front side bus on the motherboard. If the FSB
speed on the motherboard is slower than the CPU, the data will be
transferred at the
slower speed. This becomes an important consideration.
The cache size controls how
much information is queued before entering the processor. If it is not
large enough, it slows the throughput.
The number of processors on
board increases the amount of throughput. The greater the number of
ditch diggers, the quicker the ditch gets dug.
Owner reviews is important
because it lets you know what
other people think of the computer processor. It also tells you how
they use it and if
they had any problems with it.
Power requirements tell you if
you have need for a larger power supply for your system. It does not
affect the throughput of the CPU.
Socket style is important when installing CPU
correctly, but it does not affect
the throughput. It does mean however that you must get a motherboard
that
is
compatible.
After evaluating which CPU fits your budget and
has the features you want, make your selection at your favorite online computer parts store.
