How many transistors does the CPU have？
Introduction to Transistors
Strictly speaking, transistor generally refers to all single components based on semiconductor materials, including diodes, triodes, field effect transistors, thyristors, etc. made of various semiconductor materials. Transistors are sometimes referred to as transistors. There are two main categories of transistors: bipolar transistors (BJTs) and field effect transistors (FETs). The transistor has three poles; the three poles of the bipolar transistor are composed of N-type and P-type Emitter, Base and Collector respectively; The three poles of field effect transistor are respectively Source, Gate and Drain.
A transistor is a semiconductor device commonly used in amplifiers or electronically controlled switches. Transistors are the basic building blocks that regulate the operation of computers, cell phones, and all other modern electronic circuits. Because of their fast response and high accuracy, transistors are used for a wide variety of digital and analog functions, including amplification, switching, voltage regulation, signal modulation, and oscillators. Transistors can be individually packaged or part of an integrated circuit in a very small area that can accommodate a hundred million or more transistors.
The number of CPU transistors in the past dynasties
Moore's Law, that is, when the price remains unchanged, the number of transistors that can be accommodated on an integrated circuit will double about every 18 months, and the performance will also double. Of course this is just a speculative theory, not a natural theory. But based on the history of CPU development over the past 40 years, this theory is close to accurate. We can compare, the picture shows the data of Intel series CPUs over the past 40 years.
Is the CPU hundreds of millions of transistors a whole?
The CPU mainly includes a logic operation unit, a control unit and a storage unit. Some registers are included in the logic operation and control unit, and these registers are used for the temporary storage of data in the process of processing data by the CPU.
Before understanding how the CPU works, let's briefly talk about how the CPU is produced. The CPU is made on a particularly pure silicon material. A CPU chip contains millions of tiny transistors. Transistors are chemically etched or photolithographically etched on a silicon wafer the size of a fingernail. So, in this sense, the CPU is made up of transistors. In simple terms, transistors are tiny electronic switches. They are the building blocks of a CPU. You can think of a transistor as a light switch. They have an operating bit that represents two states: ON and OFF. This switch is equivalent to the connection and disconnection of the transistor, and these two states correspond to the basic states "0" and "1" in binary! In this way, the computer has the ability to process information.
CPU production is a very high-precision process, which must be done with the help of machinery. The transistors cut from the wafer will be mechanically printed on the CPU base like printing. Good product and the maximum efficiency value of the inspection product, and then adding the shell interface becomes our common processor product.
Why does the CPU have more transistors, the better the performance?
Simply put, the cpu is like a large factory that stores switches. Each transistor is a switch. When it is off, it means 0, and when it is open, it means 1. The more transistors, the more switches. When dealing with the same problem There are more lines to go. This is like the parallel circuit when you were studying physics in junior high school. The more roads there are, the more circuits there are.
Similarly, the more transistors a CPU has, the more branches of current that can flow in a unit of time. This is reflected in the macroscopic picture, that is, the more data you can process on a CPU at the same time, and the faster the machine will be.
