Digital Media Concepts/CPU Evolution

The Birth of Microprocessors
The world's first commercial microprocessor was launched by Intel (Integrated electronics) company in 1971 and was named Intel 4004. Intel 4004 consists of four chips, namely CPU chip, ROM chip, RAM chip, and I/O chip, and has 2300 transistors in it.

First computer
The world's first computer was the ENIAC computer built at the University of Pennsylvania in 1946. This computer was started in March 1943 under the guidance of John Mauchly and J. Presper Eckert, two engineers at the Moore School of Electrical Engineering at the University of Pennsylvania. , and announced to the world on February 14, 1946.

According to information released by the University of Pennsylvania, the ENIAC computer weighs 27 tons and covers an area of 680 square feet. ENIAC stores information in the form of vacuum tube electronics, so it contains more than 17,000 vacuum tubes and has 40 panels. In order to support ENIAC's high computing power, the computer has 1,500 relays, 70,000 resistors, and 10,000 capacitors, and has a power consumption of 150 kilowatts.

Host device vs. Mobile device CPU
With the development of the times, relatively bulky host computers have gradually been eliminated and replaced by lightweight and compact mobile devices. Compared with computer CPUs that focus on performance and computing power, mobile device CPUs are more aimed at having more stable battery efficiency to ensure better battery life. Therefore, in most cases, the computing power of mobile devices is not as good as that of host computers.
