i386, i486, i586, i686?

**genesus** · 03-08-2005

I was just wondering if anyone could tell me the which processors are which, I have seen i386, i486, i586, and i686, I was just wondering which actual processors compared to which architecture type.

For example which would be a pentium 2?

Thanks for your time guys,

I guess you might not have had a 386 or 486 model computer...they were late '80s - early/mid 90's processor models. Sigh - I'm old

i586 is for the Intel Pentium (as released circa 1994), and later compatible
models from Intel, AMD, et al.

i686 refers to for Pentium II and later.

i386 binaries will work on i486, i586, and i686 processors, but not necessarily the other way around (sometimes an i686-optimized binary will seem slower on an i586 machine and sometimes it won't work at all).

i386 = Intel 386 and above
i486 = Intel 486 and above
i586 = Pentium and above
i686 = Pentium 2, Pentium 2 Celeron, and above

I'm not sure whether or not Pentium Pro is capable of i686 code.

Ok, thanks alot, I appreciate the response, oh I remember some of the older models just not the syntax, thats before I knew what hardware was, but sure knew how to play around with logos and oregon trail!

thanks again man

I guess it is. I'm also a FreeBSD user, and, every time that I build my kernel (on my P4 machine), and I choose i686 architecture, it passes a pentiumpro to gcc.

Indeed. Where else can a young child learn that even bankers get dysentery and die 5 miles from your goal, regardless of how many pounds of supplies you brought with you.

Ah, bitterness.

I have noticed the i686 optimized distro(s) are faster than the others non-i686 optimized at least on my amd athlon xp-m 2800+ laptop

Only 1 i386 distro has been another story that is Componentized Linux > Progeny > Loco Linux > Mo Linux > Underground Desktop , that special stuff componentized linux" for some reason makes it seem faster and fastest of anything I've used.

Interesting avatar Vector but what distro are you using
