   Theses two are essentially equivalent.

   Thit Intel chip performs slightly better, but not a lot.  They appear
to perform about 30% better than the DX2s

   A P90 flat out smokes a 486DX4.  My best guess is another 40% performance
increase when compared to either of the DX4 products.  Not only is the
Pentium an inherently faster processor (both integer and fp, but especially
fp), the bus bandwidth to memory is much larger.

In the 486 lines, the INTEL and AMD parts are very comparible, with a slight
edge to INTEL's DX4 over AMD's.  The INTEL DX4 has a larger internal cache.

   Now, I suspect you have a reason for asking the question, such as getting
ready to upgrade a system.  If you have the appropriate socket, a DX4 is a
reasonable choice, and far preferrable bang/buck over the DX2.  Obviously,
going to a Pentium would require a MB change, and now you start paying some
premium for the new performance.
   If you're talking about replacing the mb anyway, or purchasing a new system,
I would definitely, without hesitation, recommend going to a Pentium, preferrably
on a board which uses the Triton chip set.  Intel makes such a board (Zappa),
but there are a couple of other mother boards out there with this chip set
which work well.  A possible alternative to the Triton chip set is the Opti
set, but I'm not familiar enough with this chip set to make a recommendation
one way or another.  A motherboard with a P90, Triton chip set, and Socket 7
(not 5), will give you excellent performance today, and a good upgrade path.
Once again, I recommend spending the extra couple of bucks for the Socket 7,
so that you have an upgrade path to the higher performance chips, if and when
they become available.

   You didn't ask about the 75 MHz Pentium, but my understanding is that it
performs better than the DX4 as well (once again, especially fp), and is a
bit cheaper than the P90.  A 75 in the same board would still perform very
well, and save you a couple of bucks to boot.
