Most commercial mapping programs have pretty humble processor requirements. To use these programs, your computer should have a modern Pentium or similar chip with a minimum speed of 300 MHz. That’s a pretty meager amount of computing power considering that current computers offer at least six times greater processor speed, if not more. If you’re using commercial mapping software, just about any contemporary computer is going to fit the bill when it comes to processor requirements. You’ll want a faster processor and more computing horsepower if you’re doing a lot of 3-D mapping or processing large amounts of map data — particularly creating maps from data that you download from the Internet. This can be a processor-intensive task: The faster the chip, the quicker the map or terrain image will be rendered and displayed. (Any Pentium III or above PC with a processor speed of over 1.2 GHz should suffice for the average map user.)
