Stata does not currently have multiple-processor support but it is something
we would like to explore in the future.

Since Stata will only run on a single processor, then comparing the current
high-end single Motorola PowerPC processor (1.25GHz) versus an Intel Pentium 4
processor (2.5GHz+) suggests you'll get greater performance out of a PC.

Stata's lack of Altivec support was mentioned in another post.  Altivec (or
the Velocity Engine as Apple calls it) increases performance of
single-precision operations whereas Stata works in double-precision.  Altivec
is great for things such as digital video, graphics and 3D games, and even
some scientific applications but not appropriate for applications that require
high-precision such as Stata.
