From the HP Apollo 9000 Series 700 Performance Brief, dated January of 1992:

------------------------------------------------------------------------------
The results that follow are from the Volume 1, Number 2 GPC Quarterly
report.  (GPC is the Graphics Performance Characterization committee.)
Silicon Graphics did not report results in time for this publication.
The numbers here are considered "beta" results, as all of the vendors
are still working on their ports to the PLB (picture level benchmark)
environment.

The HP systems used their Starbase graphics library.  They claim that similar
results are obtained with their implementation of the standard PHIGS library.

Higher numbers indicate better results.

The pc_board benchmark is representative of an application in the electrical
computer aided design (ECAD) market.  The test pans and zooms a printed circuit
board layout for 560 frames.  The average number of two dimensional vectors
per frame is 5655.3.  This benchmark also has an average of 6923.8 markers
and 882.7 characters per frame.

The sys_chassis benchmark is a wireframe model of a computer chassis.
It is representative of the type of data required for 3-D wireframe
applications, which are typical applications in the mechanical
computer aided design (MCAD) market.  The test rotates, pans, zooms and
views the model from different perspectives.  The chassis model consists
of 6107 3-D solid polylines and 158 3-D dashed polylines.  The number of
vertices per polyline ranges from 2 to 11 with a total of 19064 vectors.
The test displays 500 frames.

The cyl_head benchmark is a 3-D solid model of an automobile engine's cylinder
head.  The head, which is rotated, translated, and zoomed during the test,
consists of 3621 3-D polygons, and 32 3-D fill area sets.  All of the colors
are true RGB colors, and all of the polygons are Gouraud shaded.  This 
benchmark uses three light sources with ambient, diffuse and specular
components.  Because of the requirements for these capabilities, not all
graphics subsystems will support this benchmark.

The head benchmark is a 3-D human head modeled with data generated by a laser
scanner.  This type of data is typical for such application areas as animation
and biomedical.  This benchmark generates 240 frames.  The data set has nearly
60000 triangles rendered using triangle strips.  There are four directional
light sources.  Not all hardware can support this benchmark.

The shuttle benchmark depicts the rendezvous of a space shuttle and a
satellite.  The shuttle and satellite are modeled using quadrilateral meshes,
triangle strips, and polygons.  There are a total of 3355 facets.  Three
light sources are used.  This benchmark provides an example of low end
simulation.  Again, some systems do not support the required features.
------------------------------------------------------------------------------

All systems(*) tested were configured with 16 MB of memory.  The HP
systems used a single 420 MB SCSI disk; graphics transport was through
shared memory.  The DEC 5000/200 PXGT used two RZ55 332 MB external
disks via TurboChannel; graphics transport was through shared memory.
The IBM RS600/320e used a 400 MB "direct connect internal" disk and a
320MB internal SCSI disk.  The Sun SS2 GX used a 208 MB internal SCSI disk.
The IBM and Sun graphics transports were through UN*X Domain sockets.

(*)  The IBM was alone in having 32 MB of main memory.

The Sun ran SunOS 4.0.1; the IBM ran AIX; the DEC ran Ultrix 4.1; the HPs all
ran HP-UX 8.07.
