Personal IRIS benchmarks

[Simon John Gibbs]

The "premiere" issue of MIPS magazine (Feb. 89) has a review
of the Personal Iris. There are some numbers given for graphics
performance: about 16,000 vectors/sec. and less than 1000
polygons/sec. (here numbers are given for 1 light source, 2 light
sources, shaded, and different image sizes - 1/4 screen, 1/2 screen
and full screen). Anyway, they don't give much more information
about these measurements but I was surprised that they're so low. Do
these numbers make sense? What about the 100,000 polygons/sec. figure
that's so frequently mentioned?
