History of CPU:

Some of the important events in History of CPU since its invention till date are as follows:

• In 1823, Baron Jons Jackob Berzelius discovered silicon that is the main component of CPU till date helps alot in history of CPU.
• In 1903, Nikola Tesla got gates or switches patented, which are electrical logic circuits.
• In December 1947, John Bardeen, William Shockley, and Walter Brattain invented the first transistor at the Bell Laboratories and got it patented in 1948.
• In 1958, the first working integrated circuit was developed by Robert Noyce and Jack Kilby.
• In 1960, IBM established the first mass-production facility for transistors in New York.
• In 1968, Robert Noyce and Gordon Moore founded Intel Corporation.
• AMD (Advanced Micro Devices) was founded in May 1969.
• In 1971, Intel introduced the first microprocessor, the Intel 4004, with the help of Ted Hoff.
• In 1972, Intel introduced the 8008 processor; in 1976, Intel 8086 was introduced, and in June 1979, Intel 8088 was released.
• In 1979, a 16/32-bit processor, the Motorola 68000, was released. Later, it was used as a processor for the Apple Macintosh and Amiga computers.
• In 1987, Sun introduced the SPARC processor.
• In March 1991, AMD introduced the AM386 microprocessor family.
• In March 1993, Intel released the Pentium processor. In 1995, Cyrix introduced the Cx5x86 processor to give competition to Intel Pentium processors.
• In January 1999, Intel introduced the Celeron 366 MHz and 400 MHz processors.
• In April 2005, AMD introduced its first dual-core processor.
• In 2006, Intel introduced the Core 2 Duo processor.
• In 2007, Intel introduced different types of Core 2 Quad processors.
• In April 2008, Intel introduced the first series of Intel Atom processors, the Z5xx series. They were single-core processors with a 200 MHz GPU.
• In September 2009, Intel released the first Core i5 desktop processor with four cores.
• In January 2010, Intel released many processors such as Core 2 Quad processor Q9500, first Core i3 and i5 mobile processors, first Core i3 and i5 desktop processors. In the same year in July, it released the first Core i7 desktop processor with six cores.
• In June 2017, Intel introduced the first Core i9 desktop processor.
• In April 2018, Intel released the first Core i9 mobile processor.
