x86, also commonly referred to as IA-32, are processors that are descendants, or share the same basic instruction set with, the original 8086 processor from Intel. With regards to Linux, it relates more to 32-bit descendants of the 80386. Processors which fall into this category, and can thus run Linux, include:
- Intel 80386 - Referred to as i386. Very few modern distros can run on these, due to changes in GCC and glibc.
- Intel 80486 - Referred to as i486.
- Intel Pentium - Referred to as i586
- Intel Pentium Pro - Referred to as i686. Most modern distros fall into this category, and are optimized for this or later processors.
- Intel Pentium II
- Intel Pentium III
- Intel Celeron - Note that Celerons are stripped-down versions of the Pentium II and later.
- Intel Pentium 4
- Intel Xeon - Xeons are high-end versions of the Pentium II and later.
- Intel Core - Includes Solo and Duo versions.
- Intel Core 2 - Includes Solo, Duo, and Quad versions.
