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
