Arm in the Cloud?: Lower Cost and Higher Performance

A quick tutorial on why Arm technology has 90% of the cell phone market

Central processing units (CPUs) are usually classified according to their architecture. Historically, desktop computers (especially non-Apple computers) were almost entirely based on Intel’s x86 32-bit architecture, with more recent ones supporting AMD’s 64-bit extensions for more modern computers. The x86 architecture has never ruled because it was a great architecture for the future, but merely because of compatibility — essentially, if you write software to one architecture, it won’t run on another one. The one company that pushed more aggressively for new architectures was Apple, which switched its Macintosh operating system through four major CPU architectures: Motorola 68k, PowerPC, Intel x86, and now Arm. Not only that, their earlier Apple II series ran yet another CPU architecture—the 6502. Because Apple…
