关于Fedaro14到疑问,i386 or i686

发布时间:2010-11-06 20:59:27来源:红联作者:pallana
我下载了Fedora14.的32位版本,安装好后运行命令uname,显示如下
$ uname -a
Linux localhost.localdomain 2.6.35.6-45.fc14.i686 #1 SMP Mon Oct 18 23:56:17 UTC 2010 i686 i686 i386 GNU/Linux


不是说i386是32位到吗,这个i686是什么?

    呵呵 应该是和指令集相关吧

    x86_64 才是64位的。
    x86_X86一般是32位的。。。

    These are the designations you will typically run into:

    x86_64 Processors
    * AMD's Athlon 64, Athlon 64-FX, and Opteron
    * Intel EMT64 processors - Nocona Xeon, Pentium 4's using the E0 revision of the Prescott core (AKA Pentium 4, model F)

    i686 Processors
    * All Intel 32-bit Pentiums (excluding Pentium 1 and Pentium MMX)
    * All AMD 32-bit Athlons

    i586 Processors
    * All 32-bit AMD Ks
    * Pentium 1
    * Pentium MMX

    i386 Processors
    * A generic "lowest common denominator" designation for Intel 80386 compatible CPUs (includes all of the above, but does not take advantage of extended instructions on those later CPUs).

    都是32位操作系统。

    好像i686是针对大内存的内核哈

  9. anlingzhiyu 于 2010-11-06 22:20:09发表:

    奔腾是i386,奔腾4是i586,酷睿是i686,与支持的指令集有关系吧

    原来i386 i586 i686都是32位的X86,我还以为装成了64位到呢
