推荐答案

x86 是它构建运行的架构的名称(名称来自一系列旧的 Intel 处理器，它们的名称都以 86，其中第一个是 8086).虽然 x86 最初是 16 位架构，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 实际上更正确的是x86-64"——x86 的 64 位扩展.它是由 AMD 在英特尔的许可下开发的，这可能是命名法上的差异的原因(这也是两种架构长期同时使用的事实，因此标记区别很重要).不过，考虑到所有因素，只说 x64 更容易，所以我们坚持这样做.

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.
