What is CPU speed? What does it mean in electronic, mobile devices?

If you are looking to buy a smartphone or computer for work, entertainment as well as other purposes, surely one of the factors to consider is CPU speed. So how is it necessary and important to your device, let’s find out!

What is CPU?

Referring to a computer or a strong or weak smartphone, it is impossible not to mention the CPU, the main important component of a device.

CPU (Central Processing Unit), also known as central processing unit, is considered the main brain of a device whose main role is to process programs, input data from software and running hardware. on the computer.

What is CPU speed?

CPU speed or CPU clock speed is measured in gigahertz or GHz which represents the number of processing cycles per second that the CPU can perform. For an easy example, a CPU clocked at 3.4 GHz can perform 3,400,000,000 rotations per second.

CPU clock speed is a metric to assess how fast the CPU’s performance is at processing data. The simplest is to compare the two CPUs on the same line, you can evaluate the CPU’s clock.

Assuming two Core i5 models belong to the Haswell generation, the difference between them lies in the clock. One model is clocked at 3.4 Ghz and the other is 2.6 Ghz. Thus, it can be seen that the 3.4 Ghz CPU model will be up to 30% faster than 2.6 Ghz when both operate at maximum capacity.

Where does a powerful CPU come from?

A clock parameter on the CPU is not all to judge whether that CPU works on a powerful electronic device, but it also depends on many other parameters and factors:

– Number of cores / cores (Core) : each core of the CPU is a separate physical CPU from other cores. For example, 2 cores, 4 cores or 8 cores are similar to having 2 – 4 – 8 separate physical CPUs. This is what will process data and run programs or other tasks. The more cores your CPU is capable of doing at the same time or rendering faster.

– Number of threads (Threads) : this parameter tells us how many lines (threads) give data to the CPU for processing. The more threads there are, the easier the data will be to circulate and the faster the CPU will process.

– Cache memory (Cache) : is a place to store data and wait for the computer hardware to process. Its purpose is to speed up processing, it is like a transit station or cargo port.

– Turbo Boost : is a performance enhancement technology that helps the system operate at a higher speed while extending battery life. Turbo Boost automatically adjusts the clocks of each core independently to suit processing needs.

– Manufacturing process : Basically, inside the CPU contains billions of tiny transistors. The number of nm that we often call “14nm process” or “7nm process” is the size of these transistors. The smaller these transistors are, the less power they use and can help gauge the power of a CPU.

Above are a few parameters to evaluate the power, performance as well as processing speed on a CPU, and a strong CPU depends on many other factors.

With a current development technology, the companies are increasingly releasing extremely quality CPU chip models, promising that more new generation CPU chips will be developed and upgraded on the market.

Hopefully, this article will help you get more information about CPU processing speed and find yourself a suitable CPU.
