Your PC’s Performance Features
Advantages of Dual Processor Configurations
The Advantages of Dual
Processing in your PC
Your HP Vectra PC is able to bring the advantages of multiprocessing to
your desktop. With two processor’s installed, the power of your PC is
significantly increased. However, this does not mean that your PC can
process individual commands and instructions more quickly. Instead,
your processing capacity is increased, meaning that your PC can
process more commands and instructions at one time.
The use you make of the second processor will be determined by the
applications you use. To illustrate this, assume you are running a
multithreaded operating system with the following applications:
One single-threaded application.
Both processors are able to share the operating system’s work, but
all the work for the application must still be carried out by a single
processor. The performance of your PC may be faster than if you had
only one processor installed, but not by a significant factor.
Two or more single-threaded applications simultaneously.
Each processor will perform the work for different applications. The
performance of your PC will be significantly improved by the second
processor.
A multithreaded application.
Both processors are able to share the work of the application. All
work is shared and so the performance will be significantly increased
with respect to a single processor configuration. Multithreaded
applications will gain the maximum benefit from installation of a
second Pentium Pro processor in your PC.
NOTE
The advanced Pentium Pro processor provides the best performance
when used with 32-bit operating systems and applications.
