Once upon a time, though, the state of the art was much less capable; Intel’s first microprocessor, the 4004, was built on a humble 4-bit architecture with limited instructions.

A schematic diagram offers details of the Intel 4004 microprocessor. The Intel 4004 was a 4-bit chip built on a 10 µm node. It packed 2,300 transistors and operated at a clock speed of 740KHz.

The first microprocessor. Designed by Marcian E. "Ted" Hoff at Intel in 1971, the 4004 was a 4-bit, general-purpose CPU initially developed for the Japanese Busicom calculator. Running at a clock ...

The video goes through the differences between the 4-bit Intel 4004 and the 20-bit MP944, questioning whether the 4004 is even really an MPU, the capabilities of the MP944 and its system architecture.
