Factors That Affect Processor Performance

The performance of a computer is highly dependent upon the way its processor works. It is very important for the processor to work efficiently, so that the computer is able to deliver its true potential for a long period of time.

There are a number of factors which have an impact on the performance of the processor. The knowledge about these factors would certainly help in building a perfect system according to your needs. In this article, we are going to discuss about the most significant factors affecting processor performance.

Factors Affecting Processor Performance

Instruction Set

Instruction set refers to built in code of the processor, which instructs the system about the method of performing its duties. It is true that you cannot do anything about the instruction set of a particular processor, as it is a built-in feature of the CPU (central processing Unit).

However, it is essential to have knowledge about this as it plays a great role in determining the efficacy of a computer along with the architecture of the processor.


Bandwidth of a processor helps in determining the amount of information that can be processed by a processor when an instruction is given. The bandwidth is measured in the form of bits. It is seen that most of the computers work on 32 bit processors; however, to improve the performance of the system, it is advised to go for 64 bit CPU, thus helping to execute multiple instructions at the same time.

Clock Speed

Clock speed refers to an evaluation with respect to number of instructions that can be executed by the processor in a second. It is either stated in gigahertz (GHz) or megahertz (MHz). The faster the clock’s speed, the faster would be the processing of the data by the computer.

So, the fact cannot be denied that the speed of the clock plays a massive role in affecting processor performance. However, it should not be the only factor that should be taken into consideration while selecting a system for your home.

FSB Speed

FSB refers to front side bus, which is an interface between memory and processor. It helps in limiting the rate of transfer of data to CPU, hence putting a control on the processing of data by the CPU.

Cache Size

It is the RAM (random access memory) which provides the data to the processor. As soon as the data is delivered by the RAM, it is copied by the processor, which sends it to cache. Hence, the larger the size of the cache, the easier and faster would be the storage and processing of the data.

Heat Dissipation

At times, the processors may become too hot, which disrupts the performance of the system. The system may show errors and burn up at times. It may also lock or freeze on its own. Hence, it is very important for you to create an appropriate cooling environment for your homebuilt system, to allow the system to perform efficiently for a long period of time.
