In 2003, about $44 billion (USD) worth of microprocessors were manufactured and sold. [14] Although about half of that money was spent on CPUs used in desktop or laptop personal computers, those count for only about 0.2% of all CPUs sold.
Silicon Valley has an old saying: "The first chip costs a million dollars; the second one costs a nickel." In other words, most of the cost is in the design and the manufacturing setup: once manufacturing is underway, it costs almost nothing.[citation needed]
About 55% of all CPUs sold in the world are 8-bit microcontrollers. Over 2 billion 8-bit microcontrollers were sold in 1997. [15]
Less than 10% of all the CPUs sold in the world are 32-bit or more. Of all the 32-bit CPUs sold, about 2% are used in desktop or laptop personal computers. Most microprocessors are used in embedded control applications such as household appliances, automobiles, and computer peripherals. "Taken as a whole, the average price for a microprocessor, microcontroller, or DSP is just over $6." [16]
