System Architecture

While there are many architectures available for computing today, client computing is dominated by the X86 architecture. Recently, the x86-64 architecture has been released (commonly referred to as 64 bit computing) offering additional benefits. Virtually all personal computers purchased since 2007 have CPU hardware supporting x86-64, but operating systems fully utilizing this hardware have only recently become widespread. We only list versions that have amassed at least 0.1% of the market share during the selected time period.
