Improving the Performance of Your PC’s Processor

Improving the Performance of Your PC’s Processor

Your HP Vectra XU PC uses the most powerful processor currently

available in any HP Vectra PC: the Intel Pentium Pro. The advanced

capabilities of this processor are sufficient to handle any desktop

application you may use. However, it is also possible to further increase

the performance of your PC’s processor by replacing it with an upgrade

processor. This section explains how and why.

The Processor’s Clocks Everything your PC’s processor does is synchronized to a regular pulse

known as the processor clock. The speed of this clock defines the speed

at which your processor performs its work.

Your PC’s Pentium Pro processor uses a system board clock source of

either 60 or 66 MHz. All operations on the local bus (such as data

transfers with memory) are synchronized to this clock. Other devices

in the PC also use this clock to generate their own clock signals; for

example, the Peripheral Component Interconnect (PCI) bus controller

divides this clock in half to produce the 30 or 33 MHz PCI clock.

For its own internal operation, the Pentium Pro processor multiplies

the clock source to obtain a faster, internal clock. It is the frequency of

this internal clock that defines your processor’s speed. For example,

the 150 MHz processor uses the 60 MHz clock source and multiplies

this by 5/2 to produce its own 150 MHz internal clock.

PCI bus - 30 MHz Processor’s local bus - 60 MHz

Pentium Pro processor - 150 MHz
