The numbers we report in our marketting literature are actually
attainable in a real application.  When we say the VGX draws
1 million triangles per second (or whatever the number is), you
can write a C pgm to get that performance.  The numbers all
come from actual C benchmark programs.  Now this doesn't
guarantee your application can achieve these numbers, but
if you write your code carefully and operate in the same mode(s)
as the benchmark, you can.
