The processor is one of the essential components when configuring a computer. Its function is to interpret the instructions of the programs it is executing and coordinate the rest of the components with each other.
A processor has several characteristics, such as frequency, cache or its architecture.
Most users look only at the frequency when choosing the processor, but the truth is that there are other factors much more important such as architecture. The architecture determines the way the CPU works and the type of instructions the computer can execute. The more current the processor, the newer its architecture and the better and more efficient instructions it can execute. This means that at the same frequency, a more current processor, such as an Intel Core i7-8700K (Coffee Lake Architecture) is much more efficient than an Intel Core i7-3770K (Ivy Bridge Architecture).
The cache memory is responsible for storing certain types of relevant information in it, such as, on the one hand, the set of instructions that are being used the most at the moment and with a predictive character the information that the central processing unit will need to execute the following instructions. Therefore, the greater the amount of cache memory, the more optimal the performance of our processor.
There are 3 types of cache: level 1, 2 and 3. The level 1 cache is located in the processor core itself and operates at the same frequency. In multicore processors each of them has its own cache memory. It is usually very small due to its great power and price. Cache 2 and 3 are slower, but cheaper and we will find them in greater quantity in processors.
Frequency is the number of executions you can perform per second and is measured in megahertz. At this time, the normal thing is that a processor can carry out several billion instructions per second, which allows them to move all kinds of applications and games with ease.
Intel is currently the largest manufacturer of processors and has in its catalog a large group of families focused on different types of users and markets.
The best known Intel processors are those of the Intel Core family, where we find three series: i3, i5 and i7.
Each of this series in turn has different models, and approximately every year they are renewed, resulting in the arrival of a new generation (currently the eighth) that entails an increase in power and efficiency when improving an architecture or launching it on the market. a new.
These processors, regardless of the series to which they belong, can be used in all kinds of computers, from office equipment to gaming PCs, thanks to their excellent value for money.
For inexpensive and low-power computers, Intel offers its Pentium and Celeron families, while for Workstations we have the Intel Xeon.
AMD also offers us a good number of families, standing out above all Ryzen, a family of processors that, like its competitor, can be found with the Ryzen 3, Ryzen 5 and Ryzen 7 nomenclature. The Ryzen 2000 are the newest of AMD and has more than interesting models. The ZEN architecture obtains high performance in any type of task and also benefits from the use of RAM memory with high frequencies, so we recommend that if you buy a Ryzen, you invest in good RAM memory modules to get the most out of your CPU.
In AMD the basic processors are Athlon. Halfway between them and the Ryzen are the AMD FX.
For professional solutions we recommend the Threadripper, CPUs with a configuration that will shortly reach up to 64 processing threads at very moderate prices.
