I have a question, does it mean my CPU is 686? Because I saw the CPU family is 6......
Thanks!

Intel stopped using x86 names after the 80486, because they realized they cannot copyright a number.

Judging by the other numbers on this page, I don't think the family means 686. Otherwise we've got some fifteen-86's hanging around. Smilie

Oh, got it. I got confused, because I saw some released linux packages still have 586, 686 version. Why I asked this question is that I did not know which package is suitable for my cpu architecture.

If your CPU is a pentium II or newer, your CPU ought to be compatible with most binary distributions. 686 is the generic "everything newer than Pentium" group, which I consider badly named because Cyrix once made a cpu called the 686 that has little to do with it. The flags might be more important:
Code:
flags           : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss nx pni

Bolded a few you might recognize. If a program is compiled to build these things in, and and your CPU doesn't have them, these programs can crash. You're not likely to see these flags used in compilation.

Not that some programs won't use these instruction sets, they just won't be hardwired to use them. things like mplayer do lots of checks to see what instructions you have and switch routines accordingly.

Don't mix 586 and 686 packages though, keep them the same.

Corona688, thanks, learnt a lot. My understanding is: in the different released packages, the compiler option may be different, e.g., 586 and 686 package use some advanced compiler options involoving the flags you mentioned. So let's assume, we don't know what type of CPU we have, then install a 386 package is always correct, unless we have a 80286 CPU :-)
Thanks...

80386 code is less efficient, though.

Your CPU is 2GHz. This is over eight times faster than the last CPU to not be a "686". You've got nothing to worry about.
