Short History of CPUs
In 1945 the First Electronic Computer called ENIAC (Electronic Numerical Integrator and Computer) was completed. While not a CPU in the modern sense, it laid the groundwork for digital computing.
By 1947 Transistor invented. The transistor, a fundamental building block of modern CPUs, was invented at Bell Labs by John Bardeen, Walter Brattain, and William Shockley.
In 1951 UNIVAC I a first commercially available computer, the UNIVAC I, was introduced. It used vacuum tubes and punched cards for processing and was the first computer to be used for business applications.
IC (Integrated circuits)
By 1958 for the 1st time Integrated Circuits introduced. Jack Kilby and Robert Noyce independently invented the integrated circuit, which allowed multiple transistors and other components to be integrated onto a single chip. This paved the way for the development of CPUs with higher performance and lower power consumption.
Introduction of Microprocessor
By 1971, Intel 4004 - Intel released the first commercially available microprocessor, the Intel 4004. It was a 4-bit CPU designed for calculators but marked a significant milestone in the development of CPUs.
Again in 1974 Intel 8080 produced. The Intel 8080 microprocessor was released, which became popular in early personal computers such as the Altair 8800. It was an 8-bit CPU and served as the basis for subsequent CPU architectures.
By 1978, Intel 8086 - Intel introduced the 16-bit Intel 8086 microprocessor, which formed the foundation for the x86 CPU architecture that is still widely used today.
In 198, IBM PC - IBM launched the IBM Personal Computer, or IBM PC, which utilized an Intel 8088 processor. The success of the IBM PC helped establish the x86 architecture as the dominant CPU architecture in the personal computer industry.
1993: Pentium Processors - Intel released the first Pentium processors, which marked a significant jump in performance and introduced superscalar architecture, allowing multiple instructions to be executed simultaneously.
2006: Multi-Core Processors - CPU manufacturers, including Intel and AMD, started introducing multi-core processors, which contained multiple processing cores on a single chip. This led to increased performance and improved multitasking capabilities.
Introduction of core i-series
By 2011, Introduction of Intel Core i-Series - Intel launched the first generation of its Core i-Series processors, which brought significant performance improvements and advanced features such as Turbo Boost and Hyper-Threading.
By 2019 AMD Ryzen 3000 Series, AMD released its Ryzen 3000 series processors based on the Zen 2 architecture. These processors offered competitive performance and power efficiency compared to Intel's offerings.
