The first computer processors with multi core processors appeared on the consumer market in the middle of the 2000s, but many users still do not quite understand what multicore processors are, and how to understand their characteristics.
we will try to answer one very simple and at the same time a very difficult question: how to choose a CPU?
Whether you are upgrading your computer or planning to build a new PC, the choice of processor will be one of the most important.
For example, higher clock speeds, the number of cores can seriously affect overall performance, a faster system, more comfortable gameplay, as well as processor-dependent applications related to video editing and rendering.
CPU Cache is important. Without it, from the high processor clock speed, there would be no use. The cache allows you to use any, even the “slowest” RAM on your computer, without noticeable damage to its performance.
Computer processors have made a significant breakthrough in development over the past few years. The size of transistors decreases every year, and productivity is growing. At the same time, Moore’s law is already becoming irrelevant. As for the performance of processors, it should be taken into account, not only the number of transistors and frequency, but also the cache volume.
You may have already heard about the memory cache when you were looking for processor information. But, usually, we do not pay much attention to these numbers, they do not even stand out much in advertising processors. Let’s look at what the processor cache effects, what types of cache are and how it all works.
Solving any task, the computer processor receives from the RAM the necessary blocks of information. Having processed them, it writes the results of calculations into memory and receives the following blocks for processing. This continues until the task is completed.
All mentioned operations are performed at a very high speed. However, even the fastest RAM is slower than any “leisurely” processor. Each reading of information from it and writing it back is time consuming. On average, the speed of RAM is 16 – 17 times lower than the processor speed.
