How can you compare processor performance?

Virtually every site devoted to computer technology, compares the performance of processors. This topic is so important and in demand that even schoolchildren often discuss it. Consultants in computer stores, telling the buyer about the advantages of a particular model, sometimes refer to tables in which you can see a comparison of the performance of processors. And on the basis of this, the buyer argues his words.

Important parameter

Why do I need to compare the performance of the processors? It's hard to believe, but there is no unequivocal answer. At least because some people use the results to select the desired model, and others - to boast to friends of his "super-fast computer."

It is known that each CPU is characterized by speed (that is, the number of elementary operations performed by it per unit of time). The more this number, the more productive the computer system, assembled on the basis of this model of the chip. True, provided that other components are not the notorious "bottleneck" that clamps the potential within certain limits. Comparing the performance of processors allows you to specify the most "advanced" solution (without taking into account the influence of other components). Very useful feature!

Practice

To move from abstraction to reality, let's look at the life situation in which everyone can turn out. Suppose that a person decided to buy their first laptop, prepared the necessary amount of money and went to the store. There, on the shelves, shining glistening neat notebooks. And one is more beautiful than the other. Comparing the cost and the means, the available assortment can be narrowed down to several models. Which of them is better? To answer this question, you need to compare the performance of laptop processors. That is, among the remaining solutions, you need to choose two or three, fully suited for the bundle (one requires Bluetooth, the other - Wi-Fi, etc.). Then perform the testing of the computational potential of the kernel. One of the best programs in this area is SiSoft Sandra. There are paid and free (Lite) versions. With the testing task, the free option is quite manageable.

After downloading the program and installing it, you need to go to the section "Module Type - Reference Tests" in the main window.

Here you should first run the "Arithmetic test" and wait for its results (write or remember them). And then the "Multimedia test".
The resulting figures give an opportunity to get an idea of the level of performance of this processor model, as in Sandra you can compare the result with others.

It remains to perform the same actions on another computer. And compare them with the previous ones. With this simple method, you can choose a laptop, which has a more efficient processor.

Of course, comparing the performance of mobile processors is not the only function of the Sandra diagnostic program. This application also allows you to find out all information about installed components.
