The document describes the specifications of microprocessors introduced by Intel from 1971 to 2011, including clock speed, bus width, number of transistors, and maximum cache memory size. Over the decades, clock speeds increased from 108KHz to 4.0GHz, bus widths increased from 4-bit to 64-bit, the number of transistors grew from 2300 to over 1 billion, and maximum cache sizes expanded from 640 bytes to 20MB. The document provides a brief overview of the major developments and improvements in Intel microprocessor specifications over 40 years.
