  I'm sure there must have been a discussion on this topic. The real question
is: Given the choice of DX50 and DX2-66 which one should I choose and why?

  I've heard people say that the clock doubled DX2-66 is 30% to 40% faster
than a non clock doubled DX50. This can't be true under all circumstances,
can it ? Is it that it's faster on average or is it that it is faster on
certain operations or what ?

  As I see it, the DX2-66 would be faster than the DX50 only when executing
instructions from the internal 8K cache. As soon as there is a need to 
access external memory or cache it would do it at 33MHz or less. On the
other hand the DX50 would just go at 50MHz all the time. Is it that for
your average application the CPU spends most of its time executing off the
on board cache with no need to access external memory ?

  Anyway, if you have some definite answers, facts or opinions backed by
some reasonble arguments, please send me some Email soon.

Thanks,
