For a long time, what is now considered to be a prime candidate for the title of the ‘world’s first microprocessor’ was a very well-kept secret for nearly 30 years. The MP944 is the inauspicious name of the chip we want to highlight today. It was developed to be the brains behind the U.S. Navy’s F-14 Tomcat’s Central Air Data Computer (CADC). Thus, it isn’t surprising that the MP944 was a cut above the Intel 4004, the world’s first commercial microprocessor, which was designed to power a desktop calculator.
They have chips with water channels cut into the die itself for 1000w/square inch compared to commercial data center chips that can do 300w/square inch.
