  The Intel 8080
The 8080 was created by the Intel with Federico Faggin as the lead designer (his last chip before he left and started Zilog).
The 8080 was released in March of 1974.
The 8080 family is also referred to as the MCS-80.

Intel is considered by many, including environmental advocacy organizations such as Don't Waste Arizona, to be open, honest and disclosive with the community.
Intel was forthright in discussing openly with the Project XL Stakeholder Team and others in the community the results of scrubber testing conducted at another Intel facility.
Intel is committing in this XL agreement to limit the emissions of two factories to minor source limits, despite the fact that the next generations of technology will be more complex.

 A Brief History of Microprocessors
The Intel 8080 used a register based architecture with registers AX, BX, CX, DX, and HL, all 16 bit but capable of being used as 8 bit register pairs so that the AX register could be used as two separate registers AH and AL.
In the case of the Intel range of microprocessors, the 8080 evolved into the 8085 (also 8 bit like the 8080), then the third generation 16 bit 8086 microprocessor which, in its 8088 pseudo 16 bit form, was used in the first IBM PCs.
Intel have gone on to develop a range of other microcontrollers that are more complex than the basic original devices (see http://developer.intel.com for more details).

The Intel 8088 was a version with an eight-bit external data bus.
The Intel 8086 was based on the design of the Intel 8080 and Intel 8085 (it was source compatible with the 8080) with a similar register set, but was expanded to 16 bits.
Intel bubble memory was on the market for a while, but faded away as better and cheaper memory technologies arrived.

 Intel 8008
The Intel 8008 was an early CPU designed and manufactured by Intel, introduced in April, 1972.
While a little slower (in terms of MIPs) than the 4-bit Intel 4004 and Intel 4040, the fact that it processed data 8-bits at a time and could access significantly more RAM actually gave it 3 to 4 times the true processing power of the 4-bit chips.
A few early computer designs were based on it, but most would use the later and greatly improved Intel 8080 instead.

In 2000, Intel shifted processor technologies to Netburst, and the Pentium 4 Range was born, along with the SSE2 instruction set.
Intel later made the SSE3 Instruction set addition to the prescott core in 2004, and in early 2005, adding support for EM64T and the NX Bit to the Pentium 4.
Intel, by 2001, were in a pact with Hewlett Packard to create a high-performance 64-Bit chip for use in the Server Market, creating the IA-64 Instruction set.

Intel 8086 and 8088 ------------------- The Intel 8086 was released on June 6, 1978.
Intel 80486 ----------- The 486 processor was roughly twice as fast as a 386 running at the same clock speed.
Intel did offer an upgrade from the 486SX to the 486DX by installing the OverDrive processor to restore the missing circuits, but at the cost of reduced proximity to the main CPU circuitry.

 Great Microprocessors of the Past and Present (V 13.4.0)
Texas Instruments followed the Intel 4004/4040 closely with the 4-bit TMS 1000, which was the first microprocessor to include enough RAM, and space for a program ROM, and I/O support on a single chip to allow it to operate without multiple external support chips, making it the first microcontroller.
The 8080 was the successor to the 8008 (April 1972, intended as a terminal controller, and similar to the 4040).
Intel updated the design with the 8085 (1976), which added two instructions to enable/disable three added interrupt pins (and the serial I/O pins), and simplified hardware by only using +5V power, and adding clock generator and bus controller circuits on-chip.
