Evolution of Intel processors

1971: The Intel 4004 

The 4004 was the world's first microprocessor, created in a single chip, and developed by Intel. It was a 4-bit CPU and was also the first available commercially. This development prompted the Busicom calculator and gave way to the way to provide "intelligence" to inanimate objects as well as the personal computer.

1972: Intel 8008

Initially coded as 1201, was asked Intel for Computer Terminal Corporation for use in its programmable terminal Datapoint 2200, but because Intel finished the project late and did not meet the expectations of Computer Terminal Corporation, was not ultimately used in the Datapoint . Subsequently Computer Terminal Corporation and Intel agreed that the i8008 could be sold to other customers.

1974: The Intel 8080

THE 8080 became the CPU of the first personal computer, the MITS Altair 8800, allegedly, named based on a target of "Starship" Spaceship of the TV show Star Trek, and IMSAI 8080 forming the basis for machines running the CP / M-80 operating system. Supporters of Altair computers could buy a computer for a price (at the time) of $ S395. In a period of a few months, tens of thousands of these PCs were sold.

1978: The Intel 8086 and 8088

 A sale made by Intel to the new personal computer division of IBM, made ​​the IBM PC Business laid great hit with the new product with the 8088, called the IBM PC. The success of 8088 propelled Intel to the list of the top 500 companies in the Fortune magazine.

1982: The Intel 80286

The 80286, popularly known as 286, was the first Intel processor that could run all the software written for its predecessor. This software compatibility remains a hallmark of Intel family of microprocessors. After 6 years of its introduction, there were an estimated 15 million 286-based PC, installed around the world.

1985: Intel 80386 

 This Intel processor, popularly called 386, joined with 275000 transistors, more than 100 times as many as in the original 4004 The 386 added a 32-bit architecture, with ability to multitask and a unit of translation of pages, which did much easier to implement operating systems that will use virtual memory.

1989: Intel 80486 

Generating 486 really meant to have a personal computer of advanced features, including an optimized instruction set, a floating point unit, or FPU, an improved interface unit bus and a unified cache, all integrated into one's own microprocessor chip. These improvements made ​​the i486 were twice as fast as the pair i386 - i387 operating at the same clock frequency. The Intel 486 processor was the first to offer an integrated math coprocessor or FPU; him that accelerated markedly the calculations

1993: The Intel Pentium 

The Pentium microprocessor had an architecture capable of executing two operations at once, thanks to its two 32-bit data pipeline each, equivalent to 486Du) and the other 486s or equivalent). Furthermore, it was equipped with a data bus of 64 bits, and allowed access to 64-bit memory (though still keeping the processor 32-bit support for internal operations, and records were also 32 bits).

1995: THE Intel Pentium Pro

Launched in fall 1995, the Pentium Pro (professional) processor was designed with a 32-bit architecture. It was used in servers and software and workstation applications (networking) quickly boosted their integration into computers.

 1997: Intel Pentium II 

A processor of 7.5 million transistors, it searches the fundamental changes from its predecessor, improving performance in the execution of 16-bit code, add the MMX instruction set and eliminate the second-level cache kernel processor, putting it on a printed circuit board next to it.

The Intel Pentium II Xeon 

 The Pentium II Xeon processors are designed to meet the performance requirements of mid-range computers, more powerful servers and workstations (workstations).

1999: Intel Celeron 

Continuing, Intel strategy in the development of processors for specific market segments, the Celeron processor is the name given to the line Intel inexpensive.

1999: Intel Pentium III 

The Pentium III processor features 70 new instructions Internet Streaming SIMD extensions that dramatically enhance the performance with advanced 3D images adding a better quality of audio, video and performance in speech recognition applications.

1999: Intel Pentium III Xeon 

The Pentium III Xeon processor extends Intel's strengths in terms of workstations (workstation) and server market segments, and adds an enhanced e-commerce applications and advanced business computing performance.
 
2000: THE Intel Pentium 4

This is a seventh-generation microprocessor based on the x86 architecture and manufactured by Intel. It is the first with a completely new design since the Pentium Pro. NetBurst architecture, which gave no significant improvement over the previous P6 was unveiled. Intel sacrificed performance for each cycle to change as many cycles per second and improved SSE instructions.

2004: Intel Pentium 4 (Prescott)

  In early February 2004, Intel introduced a new version called Pentium 4 'Prescott'. First used in its manufacture a manufacturing process of 90 nm and then changed to 65nm. The difference with the previous ones is that they have 1 MiB to 2 MiB L2 cache and 16 KB of L1 cache

 2006: THE Intel Core Duo

 Intel launched this range of dual-core processors and CPUs 2x2 MCM (Multi-Chip Module) quad core x86-64 assembly instructions, based on the new Intel Core architecture. The Core microarchitecture returned to lower CPU speeds and improved use of processor cycles both speed and power compared with preceding NetBurst of the Pentium 4 / D 2.

2008: The Intel Core Nehalem

 Intel Core i7 processor family is a quad-core Intel architecture x86-64. The Core i7 processors are the first that use Intel Nehalem microarchitecture and is the successor to the Intel Core 2 family FSB is replaced by QuickPath interface i5 and i7 (socket 1366) and in turn replaced i7, i5 and i3 (Socket 1156) by DMI northBrige removed and implementing the PCI Express ports directly. Three memory channels (data width of 192 bits): each channel can support one or two DDR3 DIMMs. The motherboard compatible with Core i7 have four (3 +1) or six DIMM slots instead of two or four, and DIMMs must be installed in groups of three, not two. The Hyperthreading was reimplemented creating logical cores. It is manufactured at 45nm architecture and 32 nm and has 731 million transistors its most powerful. He turned to use higher frequencies, although counterpart consumption soared.

2011: Intel Sandy Bridge Core 

 Come to replace the Nehalem chips with Intel Core i3, Intel Core i5 and Intel Core i7 2000 series and Pentium G.

Intel launched its processors are known as code name Sandy Bridge. These Intel Core processors that do not have substantial changes regarding Nehalem architecture, but if necessary to make them more efficient and faster than previous models. It is the second generation of Intel Core new 256-bit instruction, doubling the performance, improving 3D performance and everything that relates to multimedia operation. They arrived the first week of January 2011 and includes new instruction set called AVX and GPU up to 12 execution units

Ivy Bridge is Sandy Bridge improved to 22 nm. Arrival for 2012 is estimated and promises improved GPU and processors sexdécuple higher ranges core and quad-core in the lowest, abandoning the dual-core processors.
