Choosing a processor for a modern computer
The processor is known to be the basis of any personal computer or laptop. The processor performs the tasks of software used on a computer or laptop, processes data and performs computational operations. Therefore, usually the choice of computer components begins with the choice of processor. This article will give basic recommendations on the choice of processor.
Many people choose a processor for their computer or laptop, focusing only on its frequency. Basically, the selection goes according to the principle: more is better. Is this the right approach when choosing a processor? Not really, because besides the clock frequency the processor has many other characteristics. Let’s look at the main ones:
1. Architecture, or speaking differently, the internal design of the processor. Pay attention to what technology it is built on, which family it belongs to, which instruction sets it supports, etc.
If you are upgrading a laptop or computer and decided to install another processor, be sure to look at the type of socket in which it will be installed, otherwise the processor will not even physically “stick” into it.
2. Cache memory is a separate processor memory in which it stores frequently used data. What it is, the better. In the modern processor, the cache memory is usually two-level – the first level is directly connected with its core and has the highest speed. The second level of the memory cache is tens or even hundreds of times larger.
That it must indicate in the processor description. For example: Celeron 1.8 / 512KB / 800 MHz means that the frequency of the Celeron processor is 1.8 GHz, and the cache of the second level memory is 512 kilobytes, that is 0.5 megabytes. By modern standards, this is quite a bit, and choosing a processor with less cache memory is undesirable.
Well, what does the third parameter mean, after the slash? – you ask.
3. This is the external frequency of the processor, more precisely, the frequency of its external bus — the trunk through which data “flows” to the processor and back. The higher this frequency, the better, however, deciding to change the old processor on your computer or laptop, be sure to find out if your motherboard supports its frequency.
4. Heat dissipation depends not only on the processor power, but also on its manufacturing technology. First of all, it is necessary to pay attention to heat generation when replacing the processor in a laptop. So if in a conventional computer the cooling system can be easily replaced with a more powerful (and accordingly cumbersome), then in a laptop the dimensions of its case are unlikely to allow it.
These are only the main parameters of the processor, however, they, like its clock frequency, are far from the last.
Consult with experts, look for information, do not save on the processor, otherwise you will lose on quality. By choosing a high-quality processor, you will ensure a high lifespan of your computer or laptop.
