Examining 9 important factors that are effective in CPU efficiency

Are you looking to buy a new CPU for your computer system? Maybe you have noticed changes in the performance and efficiency of your system processor and you have no idea why this happened. In this article, we will examine the factors that affect the performance of the CPU.

The fact is that external factors such as temperature and humidity of the environment as well as internal factors such as processor speed, cache size and processor bandwidth can Effective on CPU performance. However, the question here is how important are each of the mentioned factors? To find the answer, it is better to take a deeper look at each of the mentioned factors.

1. Number of cores

CPU consists of a number of processing units as cores. Each core is designed to receive and then read execution instructions. Therefore, the more cores a processor has, the more instructions it can process at the same time.

Every program that runs on your computer is a sequential set of information called threads. ) has A single core processor can process a single thread of information at a time. Therefore, the CPU constantly switches between different threads to perform the best performance, so that the execution of the programs is done at an optimal speed. That's why manufacturers try to produce multi-core CPUs like dual-core or quad-core. In any case, the number of cores is more, your computer can manage multiple threads at the same time, and as a result, the overall performance of the system increases. It does not mean that the computer processing speed will necessarily increase. Processor cores are constantly connected with each other and for this reason, they need more energy source for processing.

2. Clock Speed (Clock Speed)

The clock speed of the processor or clock rate shows how much a CPU It is fast. Usually, the clock speed is expressed in GHz, and this quantitative scale represents the number of instruction cycles a processor is able to execute in one second. For example, a 4.2 GHz processor can perform 4.2 billion cycles in one second.

Of course, the higher the clock speed, the more cycles a processor can perform in one second. will be. CPU clock speed can be improved under a process called overclocking. If you are not satisfied with the clock speed of your processor, you can overclock your home system CPU for faster performance, but on the other hand, you should be somewhat familiar with the side effects of overclocking; Because the processor part of your system may have a problem.

3. Clock cycle

Clock cycle is an interval between two electrical pulses in a processor. Each pulse represents a signal to the CPU to perform a specific task. Older processors were designed to perform one task per clock cycle, while modern processors have the power to process multiple tasks per clock cycle. Therefore, a processor with a high clock cycle will definitely process data faster and can execute more instructions in one cycle.

4. Cache size

Each processor has a very fast memory called Cache Is. The processor uses cache memory to store instructions and information; Because it is possible to temporarily need them again. Naturally, a larger cache size boosts processor performance. Because the processor does not need a lot of time to receive the temporarily stored information in the cache.

5. Bandwidth

Bandwidth refers to the rate at which the processor can acquire or store information in the computer's memory. Memory bandwidth is often reported in bytes/second. Therefore, the larger the bandwidth of the processor, the faster the CPU can read and write information.

6. Word length

Word length, also known as word size in technology circles, means this How much information can a processor manage in one moment. The word length of a processor actually sets the size of a bit pattern that can be acquired in a single execution.

The more bits a processor can handle in a single cycle, the faster the processing speed. became. Older processors can handle a 32-bit word at a time, while modern processors are designed to have been used to have the processing power of a 64-bit word at the same time.

7. Extreme temperatures

The most common danger to your processor is overheating. This is a completely natural phenomenon that the more tasks are assigned to the processor, the temperature of the part will increase accordingly. Performing CPU operations at very high temperatures can have a negative effect on system performance, and on the other hand, the life of the CPU will be shorter. If the CPU overheats, the motherboard's temperature sensor will tell the CPU to slow down, or even in the worst case scenario, the CPU will be instructed to shut down to protect other components from overheating.

Modern CPUs can easily run up to 80 degrees Celsius on average. Of course, the latest new generation CPUs from Intel and AMD can work at a temperature of 90 degrees Celsius. For this reason, in today's most modern computer systems, running heavy programs and games can raise the temperature of the processor up to 90 degrees Celsius. Of course, if you are concerned about the health of your system's processor, you have the ability to check the CPU temperature from time to time using various software. If the CPU temperature of your system is consistently above 70 degrees Celsius, it is recommended to buy computer or laptop coolers to reduce the temperature of the component from a critical value to a better state.

It is interesting to know that very low temperature It is not suitable for the CPU part either; That is, if you put your computer system in a very cold environment, the processor may be damaged. The electricity inside the system circuit by inducing heat to the components can cause an internal condensation in the processor part and consequently destroy the cores.

8. Material of the processor

If you are a perfectionist, most likely when choosing a suitable processor for You will definitely think about the material used in the CPU of your system. Different manufacturers use different materials for their products and the results can be different. Every element of the processor, such as the materials used, can affect the overall performance. If good materials are used to make the CPU part, this processor will not experience excessive temperature increase or this phenomenon will occur less.

9- The number of running programs

Fact This is where it doesn't matter how new and expensive your system CPU is, if you make too much work out of this part, the performance of the system will definitely be lower than usual. If you constantly use heavy programs on your computer system, you will gradually notice that your computer will perform the processing process at a slower pace. Slow down the processing speed. So, if possible, close the extra programs that you don't need easily. On the other hand, it is better not to keep the computer on all the time. Otherwise, providing cooling equipment can be the only option in front of you so that the processor executes the system commands with the desired speed.
