286, 386 and 486 are, well, kinda what they say. Intel didn't start giving processors names until Pentium. Something to do with them no being able to copyright numbers as I recall. The original Pentium and Pentium MMX CPUs are i586. As are AMD K6 and K6-2/3 and so on. Pretty much everything from the Pentium II onwards (not counting x86 64bit CPUs, I have no idea what they'd be designated) is classed as i686. PII, PIII, P4, AMD K7 (Athlon, Thunderbird etc.) and so on. If I remember correctly, the x86 designation is the instruction set the processor is compatable with. With higher generations generally being able to execute code compiled for previous generations?
