Intel Celebrates 40 Years of Digital Revolution

The microprocessor has been the engine of the digital revolution that has changed our society dramatically over the past few decades, democratizing access to information and making for a more equalitarian world. This year Intel is marking 40 years since the launch of its first microprocessor, which was revealed on 15 November 1971, just over three years after the company was created. 
The 4004 was originally designed for use in a calculator, reducing the number of chips needed from twelve to four, before being marketed to a wider audience via an advert in Electronic News magazine. The chip is a 4-bit processor clocked at 740kHz, with 46 possible instructions but it introduced the Processor, RAM, and ROM setup that we still use today.

Intel now powers the majority of computers shipped today, and says that it sees Moore's law that transistor density in semiconductors will double every two years.

The 22nm 3D tri-gate transistor

FACT1: The PC is 30 years old in 2011 and its brains, the microprocessor – is even older, a staggering 40 years old.  
FACT2: In 1971, the Intel 4004 processor held 2,300 transistors. In 2010, an Intel Core processor that includes a 32nm processing die with second-generation High-k metal gate silicon technology holds 560 million transistors.
