Intel 8085:


  • General Information:

The Intel 8085 was an 8-bit microprocessor made by Intel in the mid-1970s. The range of the speed is between 3.07 MHz to 5 MHZ. The instruction set used on it is pre x86. It has a single core.

  • Evolutions:

The 8085 incorporated all the features of the 8224 (clock generator) and the 8228 (system controller) increasing the level of system integration. Unfortunately, the 8085 was not a success until 8086 processor made.

Intel 8086:


  • General Information:

The 8086 is a 16-bit microprocessor chip designed by Intel in 1978. The range of the speed is between 4.77 MHz to 10 MHZ. The instruction set used on it is x86. It has around 29,000 transistors. It has a single core.

  • Evolutions:

The architecture and the physical chip were therefore developed very quickly, and were based on the earlier 8080 and 8085 designs with a similar register set. This is because it was originally intended as a temporary substitute for the ambitious iAPX 432 project in an attempt to draw attention from the less delayed 16 and 32-bit processors of other manufacturers (such as Motorola, Zilog, and National Semiconductor).

Intel 8088:


  • General Information:

The Intel 8088 is an Intel microprocessor based on the 8086, with 16-bit registers and an 8-bit external data bus. It can address up to 1 MB of memory. The 8088 was introduced on July 1, 1979, and was used in the original IBM PC. Its speed is 4.77 MHZ. The instruction set used on it is x86. It has a single core.

  • Evolutions:

It was a modified 8085 processor. A factor for using the 8-bit Intel 8088 version was that it could use existing Intel 8085-type components, and allowed the computer to be based on a modified 8085 design.

Intel 80286:


  • General Information:

The Intel's 286, introduced on February 1, 1982, (originally named 80286, and also called iAPX 286 in the programmer's manual) was a 16-bit microprocessor with 134,000 transistors. Its Common manufacturers are Intel, AMD, Harris Corporation and Siemens AG. Its speed range is between 6 MHz to 25 MHZ. The MOSFET channel length is 1.5 µm. The instruction set used on it is x86. It has a single core.

  • Evolutions:

The 80286's performance was more than twice that of its predecessors (the Intel 8086 and Intel 8088) per clock cycle. In fact, the performance increase per clock cycle may be the largest among the generations of x86 processors. Calculation of the more complex addressing modes (such as base + index) had less clock penalty because it was performed by a special circuit in the 286 which make a better performance.

Intel 80386DX:


  • General Information:

The Intel 80386DX is a microprocessor which has been used as the central processing unit (CPU) of many personal computers since 1986. Its speed is between 16 MHz to 40 MHZ. Its Common manufacturers are Intel, AMD and IBM. The MOSFET channel length is between 1.5 µm to 1 µm. The instruction set used on it is x86 (IA-32). It has a single core.

  • Evolutions:

The Intel 80386DX was the first true 32-bit processor used on the PC platform. Its internal register size was increased to 32 bits, and its data and address buses were as well, doubling data path width to the processor and increasing addressable memory to 4 GB theoretical. The 80386DX offered more performance than the 80286 processor. That is because the 80386DX was the first to use pipelining.

Intel 80386SX:


  • General Information:

It is a Lower speed version of 80386DX. It uses a 16-bit data bus instead of a 32-bit data bus. It has a 24-bit address bus. It has a speed between 16 MHz to 33 MHz

  • Evolutions:

It was made to move the market away from the 80286 since it had roughly the same interfaces but better performance. It provides more flexibility in running existing DOS applications. Its lower performance than 80386DX because the larger width in bus.

Intel 80486DX:


  • General Information:

The Intel 80486DX made 1989. Its speed is between 16 MHz to 133 MHZ. Its FSB speed is between 16 MHz to 50 MHZ. The MOSFET channel length is 0.8 µm. Its Common manufacturers are Intel, AMD and Texas Instruments. It has a single core.

  • Evolutions:

The performance has change dramatically in this version. This is because the core of the chip can execute instructions in less time than earlier processors. Also, the execution pipeline was increased by one step. The motherboard was more efficient than before.




Intel 80486SX:


  • General Information:

The Intel's 80486SX was a modified Intel 80486DX microprocessor with its floating-point unit (FPU) disconnected. It has a speed between 16MHz to 33 MHZ.

  • Evolutions:

It was made for marketing reason because for its less coast to give the customers more choices. Rather than this, it was same as 80486DX.

Intel 80486DX2:


  • General Information:

The Intel's i486DX2 is a CPU produced by in 1992.

There is more than one version and the 80486DX2-66 is by far the most common version of this chip; a great number of these systems were produced and many are still in use today, especially in small businesses. It was the first chip to use clock doubling. It was a very popular processor for many players of video games during the early and mid 1990s. The 486DX2 systems are perfectly viable for many uses, including routine office word processing and spreadsheet work under DOS and Windows 3.x



  • Evolutions:

The 80486DX2 was identical to the 80486DX but for the addition of "clock doubling" technology, it performs two clock cycles per single cycle of the memory bus. Because of this, an 80486DX2 is faster than an i486DX-based system at the same bus speed. For instance, if the computer's main clock runs at 33 MHz, a clock-doubled CPU would run, internally, at 66 MHZ.



Intel 80486DX4 Processor:

  • General Information:

The 80486DX4 was released in 1994 continued the trend started by the 80486DX2 toward faster clock speed processors.

The FSB speed from 100 MHZ to 133 MHZ. it has .25 um to .13 um MOSFET channel length and total of 9.5 million transistor. As the earlier processor, Pentium III has a different single core such as Katmai, Coppermine, Coppermine-T and Tualatin.

  • Evolutions

The most notable evolution was the addition of SSE Instruction Set (to accelerate media processing and 3Ds graphics), and the introduction of a controversial serial number embedded in the chip during the manufacturing process.

  • SSE : Streaming SIMD Extension

The fully expanded abbreviation stands for "Streaming Single Instruction, Multiple Data Extensions”.

* SIMD is single instruction multiple data processing.

Pentium 4:


  • General Information:

The 7th generation microarchitecture Pentium 4 processor introduced in 2000 and it will be until 2008. The frequency range is 1.3 GHZ to 3.8 GHZ. FSB (Front Side Bus) speed is from 400 MT/s (Mega Transfer /s) to 1066 MT/s. Pentium 4 is .18 um to .065 um MOSFET channel length. There are different core names for the processor such Willamette, Northwood, Prescott and Cedar Mill.

  • Evolutions:

Pentium 4 introduces the SSE2 and SSE3 Instruction Set to accelerate calculations, transactions, media processing, 3D graphics, and games. They also integrated Hyper-Trading (HT), a feature to make one physical CPU working as two logical and virtual CPUs, and more other features. The Intel Pentium 4 also came in a low-end version branded Celeron (often referred to as Celeron 4), and a high-end derivative branded Xeon intended for Multiprocessor servers and work station.

Pentium M:


  • General Information:

Produced From 2003 to 2007 by Intel with CPU speeds 900 MHz to 2.26 GHz .FSB speeds 400 MT/s to 533 MT/s. MOSFET channel length 0.13 um to 0.09 um. Pentium M Core names: Banias and Dothan.

  • Evolution:

The Pentium M coupled the execution core of the Pentium III with a Pentium 4 compatible bus interface, an improved instruction decoding/issuing front end, improved branch prediction, SSE2 support, and a much larger cache. The usually power-hungry secondary cache uses an access method to avoid switching on any parts of it which are not being accessed. Other power saving methods include dynamically variable clock frequency and core voltage, allowing the Pentium M to throttle clock speed when the system is idle in order to conserve energy, using the Speed Step 3 technology (which has more sleep stages than previous versions of Speed Step). With this technology, a 1.6 GHz Pentium M can effectively throttle to clock speeds of 600 MHz, 800 MHz, 1000 MHz, 1200 MHz, 1400 MHz and 1600 MHz; these intermediate clock states allow the CPU to better throttle clock speed to suit conditions. The power requirements of the Pentium M vary from 5 watts when idle to 27 watts at full load. This is useful to notebook manufacturers as it allows them to include the Pentium M into smaller notebooks.

Intel Xeon:


  • General Information:

Intel Xeon processor is introduced in 1999 with speeds range from 1.6 GHZ to 3.6 GHZ. It is an x86 processor with different architecture such microarchitecture, Intel core and NetBurst. The processor has 1, 2 or 4 cores.

  • Evolution :

The Xeon brand refers to many families of Intel’s x88 multiprocessing CPU’s – for dual-processor (DP) and multi-processor (MP) configuration on a single motherboard targeted at non-consumer markets of server and workstation computers, and also at blade servers and embedded systems.

Intel Core Duo:


  • General Information:

Core Duo processor is not as previous Intel production which is single core processor, it has tow cores in the chip. This processor is introduced in 2006. It has speeds range from 1.06 GHZ to 2.33 GHZ. Moreover, the FSB increased to be from 533 MT/s which was a maximum in Pentium M to 667 MT/s. this processor still uses x86 architecture.

  • Evolution:

The Duo version of Intel Core includes two computational cores, providing performance per watt almost as good as any previous single core Intel processors. In battery-operated devices such as notebook computers, this translates to getting as much total work done per battery charge as with older computers, although the same total work may be done faster. When parallel computations and multiprocessing are able to utilize both cores, the Intel Core Duo delivers much higher peak speed compared to the single-core chips previously available for mobile devices.

Intel Core 2 Duo:


  • General Information:

The Core 2 brand refers to a range of Intel's consumer 64-bit dual-core and MCM (Multi chip Model) quad-core CPU with the x86-64 instruction set, and based on the Intel core microarchitecture, which derived from the 32-bit dual-core processor. It is produced in 2006 with speeds from 1.06 GHZ to 3 GHZ and FSB from 553 MT/s to 1333 MT/s.

  • Evolution:

The core microarchitecture returned to lower clock speeds and improved processors' usage of both available clock cycles and power compared with preceding NetBurst of the Pentium 4brande CPU’s. It translated into more efficient decoding stages, execution units, caches, and buses, etc, reducing the power consumption of Core 2 branded CPU’s, while enhancing their processing capacity.
