x86 和 x64 之间的最大区别是它们可以访问不同数量的 RAM。x86(32 位处理器)的最大物理内存数量有限,为 4 GB,而 x64(64 位处理器)可以处理 32、16 甚至 32 GB 的物理内存。 带有x64的计算机可以使用64位的程序和程序。但是,有32位x86的计算机只能运行32位的程序。钍是因为它们的大小与基本等级不同。较...

On the other hand, x64 is the architecture name for the extension to the x86 instruction set that enables 64-bit code. When it was initially developed, it was named as x86-64. However, people thought that the name was too length where it was later shortened to the current x64. What ...
On VS, What is the difference between x86 platform and x64 platform ? For instance, Significant figure of the smallest number is '1.110223024625157E-016' on the x86, x86 platform. Why do i have the same value? On x64 platform, shouldn't there be twice ...
x86 is an instruction set architecture (ISA), which is essentially the design of the most basic components of a processor. The ISA is a critical factor in what kind of software can run on a processor; if code can be run in a very efficient, native way or with an inefficient workaround...
The terms "x64" and "x86" refer to different computer architectures used in modern processors. They indicate whether the processor and the operating system are 64-bit or 32-bit, respectively. Understanding the difference between x64 and x86 is essential when installing software, choosing an opera...
一个小程序可能只使用第 2、3 和 4 级每个目录中的一个目录和所有 1 级目录。在具有 4KiB page 和每个页表目录 512 个条目的 x86-64 上,这允许寻址 2MiB 地址。 下图是 x64 平台,每一级页表项的详细信息。 Huge page 通常,page 大小为 4 KiB,我们也可以把 page 设置的更大,以减少地址翻译的过程,...
This is somewhat different from your measurements - the performance of each method more or less flips depending on x86 versus x64. Your measurements have much more stark differences, particularly between each implementation and its other-arch counterpart. RawModulo_5 is a l...
x86/x64 and arm. while both perform the same basic functions, they have some key differences that may make one preferable over another depending on what type of device you are using. x86/x64 cpus are designed for desktop computers, laptops, and servers. they are powerful processors that ...
More specifically, 64 bits is the size of the registers on a 64-bit CPU's microprocessor or the computer bus.64-bit hardware, and the software compiled to run on it, is sometimes called x86-64. This name refers to the fact that it is a 64-bit architecture, and is compatible with ...
