The atom at 1.6GHz is roughly equivalant to a Pentium 3 at 800 to 1000Mhz
on most things.  The Pentium 4 was especially bad at some tasks which
made it really slow at times (I had one case where a 2ghz athlon 64 did
the same task 5 times faster than a 2.8ghz P4).

The P4 was simply a bad design.  The atom isn't a bad design, but one
has to be aware of the tradeoffs made in the design in some cases.
