cat /proc/cpuinfo

Mine gives the following

{it actually gives another page, 'cause I've got two processors, but this
is a good enough indication}

The Pentium 3 is the Pentium 3 - Intel stopped using the x86 naming
standard after the {I think} 486 series of processors after a US court
ruled that they couldn't sue AMD {or Cyrix} for calling their processor a
586 as you can't trademark a series of numbers.

The name "Pentium" refers to the 5th generation processor made by Intel
{8086, 80286, 80386, 80486, Pentium} - Penta being 5.
