Easy cowboy, don't rewrite history. In 1971, the 4004 had only 2,250 transistors. Cool, but not exactly mind blowing. Saved some space on the circuit boards for sure.
The Intel 4004 is a 4-bit central processing unit (CPU) released by Intel Corporation in 1971. It was the first commercially produced microprocessor,[2] and the first in a long line of Intel CPUs.
