Your System’s Processor

Your System’s Processor

The key to the power of your HP Vectra XW is the high-performance

processor its uses: the Intel Pentium Pro. The capabilities of this

processor are sufficient to handle any 3D-graphic or multi-media

application you may use.

The Processor’s Clocks Everything your system’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.

The 200 MHz Pentium Pro processor uses a system board clock source

of 66 MHz. All operations on the local bus (such as data transfers with

memory) are synchronized to this clock. Other devices in the system

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 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. The 200 MHz

processor in your Vectra XW uses the 66 MHz clock source and

multiplies this by 3 to produce its own 200 MHz internal clock.

PCI bus - 33 MHz Processor’s local bus - 66 MHz

Pentium Pro processor - 200 MHz
