Frequently asked questions
What is a processor?
The processor is the brain of the computer. A processor is a device capable of processing program code and defining the basic functions of a computer for processing information.
Structurally, the processors can be executed as one large single integrated chip, and in the form of several chips, blocks of electronic boards and devices.
The work of various applications is based on the execution of a certain sequence of commands and data placed in so-called registers of the processor. The power, and as a consequence, the speed of the computer, is determined by the speed of matching the data and the corresponding commands for processing them. The main characteristics that differentiate different types of processors are the clock frequency, bit depth and the size of the internal cache memory.
Which processor is best to buy?
To date, the main processor manufacturers are Intel and AMD. Intel processors are characterized by higher quality and performance, but they are expensive, which is not always justified, for example, when buying budget models.
Processors from AMD are distinguished by a rather favorable price / quality ratio, however some models tend to overheat. Despite technological backwardness, and not always high quality, AMD products enjoy a good demand in the market, which is due, first of all, to the low price in comparison with the main competitor.
When and why you need to check the processor?
In practice the CPU of the computer rarely fails. Much more often, the cause of the instability of the computer is its RAM. If your computer suddenly freezes, reboots, closes applications spontaneously or if there are other problems in its RAM, test it first.
If everything is OK with the computer's memory, and the computer still does not work stably, you should check the processor, as well as other devices included in its composition.
It is recommended to check the processor for stability of operation also in case of purchase of the computer (or separately the processor), even if at first glance it works normally. Such a check will provide an opportunity to immediately identify a malfunction and in time to refuse to purchase or change the equipment under warranty.
It is necessary to check the processor also after it is overclocked. If the processor in the overclocked state is working with errors, it is advisable to reduce the degree of overclocking to achieve stability. This will avoid many problems in the future.
It is sometimes advisable to check the processor just to be sure of the reliability of your computer, as well as in some other cases.
What is the clock frequency?
The processor clock frequency determines the minimum time quantum for which the processor performs some conditional elementary operation. Clock frequencies are measured in megahertz and determine the quantitative performance characteristics of computer systems in general. The higher the clock speed, the faster the CPU is operating.
What is the processor cache?
Solving any problem, the computer processor receives from the operative memory the necessary blocks of information. After processing them, it writes the results of calculations into memory and receives the following blocks for processing. This continues until the task is completed.
All these operations are performed at very high speed. However, even the fastest RAM runs slower than any "slow" processor. Each reading of information from it and its reverse recording take a lot of time. On average, the operating speed of RAM is 16 - 17 times lower than the speed of the processor.
Despite this imbalance, the processor does not stand idle and does not expect every time the RAM "issues" or "receives" data. It almost always works at maximum speed. And all thanks to the availability of his cache.
