1 Your PC's Performance Features 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 4 English Pentium Pro processor - 150 MHz
