In this article, we are going to give all detailed information about Factors affecting the performance of the processor. People are not aware of detailed information that’s why they can’t select the proper processor for their needs when they are actually buying. You can look Best laptop under 30000 and Best laptop under 50000 to make a perfect decision of buying the best laptop of your dream
This article will help you to choose the best processor to match your need. Increasing technology and internet speed increase the importance of speed in doing tasks in daily life. To reduce the processing time of the computer, the CPU is developing at the next level.
What is the Processor?
The processor is a silicon chip attached to the motherboard of a laptop or computer. It has a number of transistors to understand binary language. The processor or CPU (Central Processing Unit) is the brain of your computer.
It interprets the process between hardware and software and gives us the output. It works on four primary functions, Fetching, decoding, execute, and write back. All the input and output operations will be performed because of this CPU.
Now the Input means the commands or instructions given by the user to computer or laptop. For example, by the double-clicking to open applications. In this case when we double click on the icon of the application we wish to open it.
We give the command or instruction to a computer, this instruction is received by a processor is called fetching. Now the given instruction is decoded in the code language which is understandable to the CPU unit.
Once the instruction decoded it will be analyzed and execute by a processor after this we are able to see the application has been opened. Now the last function writeback, in this processor again ready to perform the next task. The processor Architecture design is important for the minimum consumption of electricity and minimum error that can give an accurate result.
What is the Clock speed of the Processor?
In a simple language, we can say that Clock speed or frequency is a rate that can be taken by the processor to perform a given instruction. It measures in GHz. But if we look into technical, the clock speed is a number of clock cycles that executes in a 1 second to process many instructions.
A “cycle” is technically a pulse synchronized by an internal oscillator of a processor. If it completes 1 clock cycle in 1 sec then its clock speed is 1 Hz. 1000000 clock cycles in 1 sec then clock speed is 1MHz and if 1000000000 clock cycles in a 1 sec then its clock speed is 1GHz. You can easily understand by following the table.
|1 MHz (Megahertz)||1 Milion cycles per second||10^6 cycles in 1 sec|
|1 GHz (Gigahertz)||1 Billion cycles per second||10^9 cycles in 1 Sec|
How to Compare to Processor on the basis of clock speed?
In general, many people think a higher clock speed means a faster Processor but other factors are also come into to picture. You can not compare its performance based on only clock speed.
Depend upon the architecture design of the Processor, In some CPU a single instruction may be performed in a single clock cycle, or in some CPU many instructions might be performed in a single clock cycle.
For Example, An Intel Core i5 1st generation has a clock speed of 3.2 GHz and the latest Intel Core i5 10th generation has a clock speed of 1.6 GHz.
New Processor is working faster than the old one because newer architecture design deals with instructions more efficiently. And it splits tasks between more cores with more CPU cache. But among the same generation of Processors like i5 10 th gen and i7 10th gen. A processor with a higher clock speed will generally outperform a processor with lower clock speed.
Note: it is important to compare processors from the same brand and generation.
What is the Core of the processor?
Generally, the performance of the processor is judge by the Core. If the number of core is increasing, the performance also goes on increases. Core indicates how much the task processor can perform at one time. The core is a computational unit of CPU that reads the instructions though ALU (Arthematic logic unit).
How Processor performance depends on cores?
If the processor has only one core its means the processor has a single processing unit therefore more trouble in executing the instruction to open multiple applications at a time. So Cores are increased in a processor to improve the performance.
Multicore processors are doing many tasks faster at the same time by splitting the given task into different cores Independently, hence the speed of the processor is also improved.
Modern processors are made up of multi-cores which allowed the multiple instructions to perform tasks e.g. Watching a movie in a laptop at the same time downloading a file from the internet in the background.
Single-core, Dual-core, Quad-core, Octa-core
In olden days the Processor or CPU is made in single-core which means it had only a single circuit to process instructions. It is quite difficult to perform a multi-task, But nowadays development in CPU with multicores. In dual-core processor two independent cores or circuit is there to work on instruction independently at the same time similarly quad-core has four cores and octa-core has eight cores.
The people are ready to spend more money on a powerful CPU, the concept is behind that is splitting a workload into multiple processing cores so CPU can work on the same load but on the different parts at the same time. Because of these cores, the performance of the is improved. It is much faster, it also consumes less power and efficiency is higher.
If you see the two partitions on a processor it is a dual-core. If four partitions it is a quad-core if eight partitions the is octa-core, so like that you can easily identify.
What is Overclocking?
Every processor is designed with some clock speed to execute an instruction in a cycle. All processors consume a specific power as per his architecture design. But to increase the performance of a processor, supplying more power so it can perform faster, its called an overclocking.
Supplying more power than decided one so the processor can perform even faster. Usually, the extra power of 10 to 20 % is giving to perform some better and faster.
Disadvantages of overclocking
Because of extra power supply than decided, the more heating of processor tales place. We have to take care of more heat by providing a better cooling system. Otherwise, it will get damaged due to overheating.
Turbo Boost Technology
To overcome the overheating due to overclocking, Intel came with new turbo boost technology. The main function of turbo boost technology is, it will automatically manage the clock speed according to load as well as heating.
For example, if you are doing light work CPU work on 2.3 GHz clock speed. But if u doing video editing or playing high graphics games the load on CPU is more. As a result of turbo boost technology, the CPU manages the clock speed of 3.2 GHz.
Similarly, when the heat CPU increases, the CPU reduces the clock speed automatically so heat will minimize for some period of time. CPU perfume better and faster due to turbo boost technology in which it manages clock speed itself according to load.
