The CPU of a computer is the microprocessor. Intel processorsFacts8085It is an NMOS-based 8-bit microprocessor invented by Intel in 1977. It is used in washing machines, microwave ovens, mobile phones, etcit bus speed was 2 MHz80486Intel x86 microprocessor of the fourth generation. it bus speed was 25-50 MHz. it was invented in 1989. Pentium III In 1999, it was available in the market. it allows for lightning-fast data transfers between the memory and the microprocessor. it bus speed is 100 MHz, 133 MHzDual Corethe Pentium Dual-Core trademark was used for Intel's mainstream x86-architecture microprocessors. The processors are designed for mobile or desktop computers. bus speed is 533 MHz, 667 MHz, 800 MHz, 1066 MHzTherefore, INTEL processors in increasing order of speed sequence are 8085?80486?Dual Core?Pentium III.
