INTEL History


Microprocessor
Learning about Intel microprocessor history will teach you a lot about how computer processors have evolved over the years, and how we have reached the advanced stage of processors today. Intel Corporation was founded in July 1968, and today it is the world's biggest semiconductor chip manufacturer. The proportion of personal computers that run on Intel chips today is simply mind boggling, to say the least. The company is based in Santa Clare, California and the name was coined as an abbreviation of Integrated Electronics Corporation.

The First Step

Intel 4004 was the world's first single chip microprocessor, and was created by Intel in November 1971. Ted Hoff, Federico Faggin and Stan Mazor are the people who came up with this amazing chip for the time, which combined the CPU, the memory, and the input output ports of a computer on to one single chip, which was astoundingly small for the time. This was only the beginning of the long
history of computer processors.

The need for the 4004 chip came up in 1969, when a Japanese client called Busicom asked Intel to make them 12 different chips for a variety of computing purposes, for an advanced calculator. But Intel did not have enough people to make these chips, so they suggested that they could put all the features into one single chip. Busicom agreed, and Intel microprocessor history was made


Further Developments
From then on, Intel became synonymous with integrated circuits, and they became the custom chip providers for all computer enthusiasts in the computer industry. In April 1972, the 8008 chip was introduced, which was the first 8 bit chip ever. Another two years later the 8080 chip was released, which increased the speed of functioning and the number of instructions executed per second by a great amount.

The next step was to create microcontrollers, which were literally 'computers on chips'. The 8748 microcontroller was released in 1976, and this allowed users to control events in real time and manage data at much faster speeds.

In 1978, the 8086 microprocessor was released which was a further enhancement of the 8080 chip. This chip used a 16 bit architecture, and it was followed up by the 8088 chip in 1981. Competition was slowly catching up with Intel at this time though, so they released the 80186 and the 80286 microprocessors in 1982.

The next step was to move on to 32 bit processors, and this is how the 80386 and the 80486 came up. These processors were also known as the '386' and the '486' respectively, and they were used till the early nineties. The 386 was released in 1985, and the 486 was released in 1989.

Intel Pentium Microprocessor

This list of Intel microprocessors brings us to the amazing 80586 processor, which is used even today, with several modifications and upgrades of course. The chip was initially a 32 bit chip with a speed of about 66 MHz, and the 64 bit processors that are available today, can clock speeds of up to 3.6 GHz. You must look at the Intel Core processors to see the real power and beauty of these devices, which are comfortably the best computer processors. The history of Intel processors has been long and winding, but it has culminated in a great offering to the world, which has changed our lives forever. You must also learn more about 32 bit vs. 64 bit processors.
