Well I'm a day late but anyway -

Four decades ago today — November 15, 1971 — Intel placed an advertisement for the first single-chip CPU, the Intel 4004, in Electronic News. Designed by the fantastically-forenamed Federico Faggin, Ted Hoff, and Stanley Mazor, the 4004 was a 4-bit, 16-pin microprocessor that operated at a mighty 740KHz — and at roughly eight clock cycles per instruction cycle (fetch, decode, execute), that means the chip was capable of executing up to 92,600 instructions per second. We can’t find the original list price, but one source indicates that it cost around $5 to manufacture, or $26 in today’s money.

Truly amazing how far the industry has come since then ... :)
 
The progress of CPU development/manufacture has been quite amazing in the time. Happy Birthday 4004. :)
