How many transistors are there on a CPU?

Published time: 2019-08-21

A transistor in an electronic component is a semiconductor device, and an amplifier or an electronically controlled switch is commonly used. Transistors are the basic building blocks for the operation of computers, mobile phones and all other modern electronic circuits. Due to its fast response and high accuracy, the transistor can be used for a variety of digital and analog functions including amplification, switching, regulation, signal modulation and oscillators. Transistors can be packaged individually or in a small area and can accommodate a portion of a 100 million or more transistor integrated circuit. So, this article will detail how many transistors are in the CPU?

Number of CPU transistors in the past

Moore's Law, that is, when the price remains the same, the number of transistors that can be accommodated on an integrated circuit doubles every 18 months, and performance is doubled. 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 precision.

In 2000, Pentium 4 Willamette, the production process is 180nm, the number of cpu transistors is 42 million.

The Corei7 ≤ 980X launched in 2010 has a manufacturing process of 32 nm and a number of transistors of 1,169,999 and 9,999.

The 2013 core i74960X has a manufacturing process of 22nm and a transistor count of 1.86 billion.

Detailed data about CPU in recent years

February 1999: Intel releases the Pentium III processor. The Pentium III is a 1 x 1 square silicon with 9.5 million transistors fabricated using Intel's 0.25 micron process technology.

January 2002: Intel Pentium 4 processor introduced, high-performance desktop computers can achieve 2.2 billion cycles per second. It is produced using Intel's 0.13-micron process technology and includes 55 million transistors.

March 12, 2003: The Intel Centrino mobile technology platform was born on laptops, including Intel's latest mobile processor, the Intel Pentium M processor. The processor is based on a new mobile-optimized microarchitecture, produced using Intel's 0.13-micron process technology, which includes 77 million transistors.

May 26, 2005: Intel's first mainstream dual-core processor, the Intel Pentium D processor, was born with 229,999 9999 transistors produced using Intel's leading 90nm process technology.

July 27, 2006: The Intel Core 2 Duo processor was born. The processor contains more than 290 million transistors and is manufactured in several of the world's most advanced laboratories using Intel's 65nm process technology.

January 8, 2007: In order to expand the sales of quad-core PCs to mainstream buyers, Intel released the Intel Core 2 quad-core processor and two other quad-core server processors for desktop computers with a processing capacity of 65 nanometers. . The Intel Core 2 quad-core processor contains more than 580 million transistors.


Cpu, why are more transistors stronger?

Simply put, the CPU is like a large factory that stores switches. Each transistor is a switch, which is 0 when it is turned off and 1 when it is turned on. The more transistors, the more switches there are. When you deal with the same problem, the more routes you choose. It is like a parallel circuit when you use it to learn junior high school physics. The more roads there are, the more cycles there are.

Similarly, the more transistors a CPU has, the more branches the current flows in a single unit of time. From a macro perspective, the more data you can process on the CPU, the faster the machine will be.
