推荐答案

x86是要在其上运行的体系结构的名称(该名称来自一系列旧的Intel处理器，其名称均以86结尾，其中第一个是8086).尽管x86最初是16位体系结构，但今天使用的版本是32位扩展.

x86 is the name of the architecture that it's built to run on (the name comes from a series of old Intel processors, the names of which all ended in 86, The first of which was the 8086). Although x86 was originally a 16-bit architecture, the version in use today is the 32-bit extension.

x64实际上更正确地是"x86-64"(x86的64位扩展名).它是由AMD在Intel的许可下开发的，这可能解释了命名上的差异(以及两种架构在很长一段时间内都可以同时使用的事实，因此区分这种差异很重要).尽管考虑了所有因素，但说x64还是比较容易，所以我们坚持了这一点.

x64 is actually more correctly "x86-64"--the 64-bit extension of x86. It was developed by AMD under a license from Intel, which may account for the difference in nomenclature (that and the fact that both architectures have seen simultaneous use for a long time, so marking the distinction is important). All things considered, though, it's easier to just say x64, though, so we stuck with that.
