Intel Processor Progression and Design

By accolon ·
I wondered, if anyone has run across a detailed white paper anywhere, that traces the lineage of the x86 family of processors, from the 8086, through the various iterations, right up to today.

Now, let me be clear, I'm talking about lineage, but with a lot of detailed technical info, as to what changed with the generations along the way, and how the next one in the series is X amount better in this way, and Y amount better in that way, than it's predecessor.

The source of the question, isin a recent discussion (with a superior) about the evolution of processors, and the limitations of the various processors along the way. How much ram they were limited in addressing, how they got around this, etc.

It was also argued (erroneously I believe) that a 486 was just a 386+387, and that a Pentium was just a 486x2, etc.
It was also put forth, that up until the 64bit processors, no processor could address more than 640k, without a memory manger...

I believe all of this to be false, but need proof, and truly would like to understand it once and for all, in all it's glorious detail.

In all my looking, I have yet to find anything that explains the progression. :-)

Looking for sort of a CPU-201 or 301 course, I guess you could say... and if TechRepublic doesn't have it, maybe they should after I am done! :-)

Thanks,
Andrew

I have not found a single comprehensive guide.
These links should aid you in proving your point though.

The Intel CPU data is in the Wintel section.

This is the most detailed that I have found so far.

Quite a bit of detail.

Thanks... it's taken a few days to digest some of the info, but it is along the right track.

I'm open to it, if anyone else has anything more to add... :)
