Which is important for CPU cache and main frequency?

The CPU of Mini computer is the core processor for industrial computer, and the main frequency and cache are the core structure of the CPU, which will dominate the computing speed and processing performance of the CPU. If you ask which is more important, the CPU cache or the main frequency of the Mini computer, in fact, strictly speaking, both are important, like the right arm of the CPU. Why do you say that, let's take a look through the following analysis.
Let’s talk about the CPU cache first. Take our current mainstream industrial computer CPU as an example, I7-8700.
The main frequency cache parameters are as follows:
In the parameter description,the cache of I7-8700CPU is: 12MB. What does it mean?
The cache is a component used to reduce the average time required for the processor to access the memory, and it is a secondary register of the CPU of the computer. The cache size means that when the processor CPU sends a request to the memory, if there is cache data in the processing, then our Mini computer will directly read the data from the cache after issuing an instruction, instead of calling it from the memory and then reading it. This will greatly improve the processing speed of the industrial computer, so the cache size is one of the important indicators of the CPU. The larger the cache, the better the CPU performance.
Next, let's talk about the impact of the CPU frequency on the Mini box computer.
The main frequency of the above-mentioned I7-8700CPU is: 3.2GHz. Compared with the I3-3240CPU, this main frequency is even lower than that of the I3-3240.Therefore, there is a misunderstanding here and I would like to tell you that it is not that the higher the CPU frequency, the faster the processing speed, and there is no direct proportional relationship between the two.
The main frequency only represents the task clock rate of the CPU processing a certain period of time. For example, if the main frequency is 2.0GHz, it means that the number of instructions processed in one clock cycle is 2.The main frequency is 3.0GHz, and the processing speed is 1.5 times faster than that of 2.0GHz.But these parameters refer to the case of the same core and the same thread. Of course, the main frequency is indeed one of the signs that determine the performance parameters of the CPU.
Therefore, which is more important, the CPU cache or the main frequency of the Mini computer, is actually important. Just like a chef, he must not only be able to cook food but also know how to match colors. Both are indispensable. Only in such a perfect combination can the best effect be achieved. The same is true for CPU frequency and cache.
