Intel is the world’s largest semiconductor company. The name Intel comes from the word Integrated Electronics Corporation which is founded in 1968. Not only the processors has it also manufacturing the following products Motherboard chipsets, flash memory, network cards, Ics, graphic chips, Embedded processors and many other products.
The 4004 Microprocessor is the first Microprocessor product released by Intel. It is the world’s first Single Chip Microprocessor. It was invented by Intel engineers Federico Faggin, Ted Hoff, and Stan Mazor. This Microprocessor is clocked at 740 KHz, the 4004 executed up to 92,000 single word instructions per second, could access 4 KB of program memory and 640 bytes of RAM. Although the Intel 4004 was perfect fit for calculators and similar applications it was not very suitable for microcomputer use due to its somewhat limited architecture.
In 1972 Intel released the 8008 Microprocessor. The 8008 was the first 8-bit microprocessor. The 8008 was originally code named the 1201. The Intel 8008 was a microprocessor designed for use as a terminal controller for Control Terminal Corporation (CTC). The 8008 was to be single chip version of CTCs CPU design, which was to be implemented as TTL logic chips. Work began on the 8008 before the 4004 and had circumstances been different the 8008 could have been the first microprocessor and not the 4004. The 8008 is architecturally very different than the 4004.
The 8008 was a very important transition CPU for Intel. The work on the 8008 enabled the creation of the powerful 8080 (which included the 8008 instruction set). The 8008 family is also referred to as the MCS-8.
The Intel 286, originally known as the 80286, was the first Intel processor that could run all the software written for its predecessor. This software compatibility remains a hallmark of Intels family of microprocessors. Within 6 years of its release, an estimated 15 million 286-based personal computers were installed around the world.
Intel Pentium Processor
In 1993 Intel released Pentium Processor. This processor allowed computers to more easily incorporate real world data such as speech, sound, handwriting and photographic images. The Intel Pentium brand, mentioned in the comics and on television talk shows, became a household word soon after introduction.
Intel Pentium Pro Processor
In 1995 Intel released Pentium Pro Processor. It is designed to fuel 32 ﾢﾾﾀﾾﾓ bit server and workstation applications. It supports fast computer aided design, mechanical engineering and scientific computation.
Intel Pentium II Processor
In 1997 PII processor was released. The Pentium II microprocessor was largely based upon the core of its predecessor, the Pentium Pro. However, there are some significant changes to the design of the processor. Unlike Intel’s previous Pentium and Pentium Pro processors, the Pentium II CPU was packaged in a slot-based form-factor rather than a socket. The chip and associated components were carried on a daughterboard similar to a typical expansion board within a plastic cartridge. A fixed or removable heatsink was carried on one side, sometimes using its own fan.
Intel Pentium II Xeon Processor
In 1998 they have introduced the Xeon processor. This is for the dual processor and multiprocessor configuration on single motherboard for server and work station computers. The Xeon brand has been maintained over several generations of x86 and x86-64 processors. Older models added the Xeon moniker to the end of the name of their corresponding desktop processor, but more recent models used the name Xeon on its own. The Xeon CPUs generally have more cache than their desktop counterparts in addition to multiprocessing capabilities.
Intel Celeron Processor
In 1999 Intel released the Celeron processor. They have developed this processor for specific market segment. It provides consumers great performance at an exceptional price, and it delivers excellent performance for uses such as gaming and educational software.
Intel Pentium III Processor
This Pentium III processor also released in the year 1999. It is the evolutionary upgrade from Pentium II. The first Pentium III core, Katmai, featured SSE instruction set, which allowed SSE-enabled applications to process up to four single-precision floating point numbers at once. Other Pentium 3 cores added other features, like 256 and 512 KB on-die L2 cache memory and smaller package size. During its lifetime, the core of Pentium III microprocessors was shrunk twice – from 0.25 micron to 0.18 micron, and then to 0.13 micron. It has the following advantages
1. Enhance the performance of advanced imaging
3. Streaming audio
4. Video and speech recognition applications
Intel Pentium IV Processor
In 2000 Intel released the high speed processor Pentium IV. It is having more advanced features. By using this process we can do the following process
1. Create professional-quality movies
2. Deliver TV-like video via the Internet
3. Communicate with real-time video and voice
4. Render 3D graphics in real time
5. Quickly encode music for MP3 players
6. Simultaneously run several multimedia applications while connected to the Internet
The processor debuted with 42 million transistors and circuit lines of 0.18 microns. Intels first microprocessor, the 4004, ran at 108 kilohertz (108,000 hertz), compared to the Intel Pentium 4 processors initial speed of 1.5 gigahertz (1.5 billion hertz).
Intel Itanium Processor
In 2001 they have introduced the Itanium processors. It is the first product of 64 bit from Intel. It is mainly designed for high-end, enterprise-class servers and workstations, the processor was built from the ground up with an entirely new architecture based on Intel’s Explicitly Parallel Instruction Computing (EPIC) design technology. The processor delivers world-class performance for the most demanding enterprise and high-performance computing applications, including e-Commerce security transactions, large databases, mechanical computer-aided engineering, and sophisticated scientific and engineering computing.
These are the main processors released by Intel. Apart from this they have released Itanium II processors and Pentium M Processors.
