"I think there is a world market for maybe five computers."

Thomas Watson, president of IBM, 1943



Standing in opposition to X86/X86_64 is ARM. This architecture was developed in the 1980s to cater to lower level devices like embedded systems. Nowadays ARM continues to dominate that market, with a majority of cell phones and other embedded systems equipped with ARM based processors. ARM’s great strength is its width of performance. Some ARM systems can operate in extremely low power situations, with low performance as a corollary. However other ARM systems are deployed on computers where high performance is the primary goal.

By virtue that ARM is RISC based, it is unlikely that consumers will ever see an ARM processor in their desktop PC. CISC based systems are much more appropriate for general consumer needs. Currently ARM is the most popular architecture ever produced; as of 2014, 50 billion ARM had been shipped. ARM stands as a central contrast to the likes of Intel; instead of a superfast processor that performs every task with necessary bloat, ARM performs certain tasks with extraordinary performance and power consumption.
