SPEC
(Standard Performance Evaluation Corp) is company that
develops, among other tools, a set of benchmarks which
measures the 3D rendering performance of systems running
under an OpenGL environment. It runs all of its
testing on 3D Model Design, Review, Analysis and
Verification routines, that are a basis for comparison in
CPU performance, as well as the graphics subsystem.

Set 07 and Data Explorer 06 Tests |
|
In our first
SpecViewperf test, Data Explorer - 06, SPEC describes the
test as folllows:
The IBM Visualization Data
Explorer (DX) is a general-purpose software package for
scientific data visualization and analysis. It employs a
data-flow driven client-server execution model and is
currently available on Unix workstations from Silicon
Graphics, IBM, Sun, Hewlett-Packard and Digital Equipment.
All tests assume z-buffering with one light in addition to
specification of a color at every vertex. Triangle meshes
are the primary primitives for this viewset. While Data
Explorer allows for many other modes of interaction, these
assumptions cover the majority of user interaction.
The first
version of this viewset included indirect rendering to
handle the client/server model of X-Windows-based systems.
In this version, tests with indirect rendering have been
removed to allow the viewset to be fully ported to Windows
NT and OS/2 environments.
In Data
Explorer, we see the 2.4GHz Northwood with a commanding 10%
lead over the Athlon XP 2100+. The 2.2GHz Northwood is
about 5% behind it's big brother but still ahead of the
Athlon by a 5% margin as well.
In our next
test, SpecViewperf's Design Review - 07 is described as
follows:
DesignReview is a 3D computer model review package
specifically tailored for plant design models consisting of
piping, equipment and structural elements such as I-beams,
HVAC ducting, and electrical raceways. It allows flexible
viewing and manipulation of the model for helping the design
team visually track progress, identify interferences, locate
components, and facilitate project approvals by presenting
clear presentations that technical and non-technical
audiences can understand.
DesignReview works from a memory-resident representation of
the model that is composed of high-order objects such as
pipes, elbows valves, and I-beams. During a plant
walkthrough, each view is rendered by transforming these
high-order objects to triangle strips or line strips.
Tolerancing of each object is done dynamically and only
triangles that are front facing are generated. This is
apparent in the viewset model as it is rotated. The
updated DRV-07 shaded model contains 367178 vertices in
42821 primitives. Vertex arrays are used to send the data to
mirror the current release of the Design Reivew application.
The wire frame model contains 1599755 vertices in 94275
primitives.
What we like
about these SpecViewperf tests is that they are real world,
highly compute intensive applications, that would most
definitely take advantage of an high end Pentium 4 or
Athlon's horsepower. In both the Data Explorer and
Design Reviews tests, the graphics subsystem, in this case
our GeForce3 Ti 500 cards, are also heavily weighting this
test. However, since we are comparing apples to apples
and all test systems were configured with the exact same
graphics card and driver set, we have consistent, repeatable
and valid results. Here the Pentium 4 2.4GHz CPU has
an impressive 28% lead over the Athlon XP 2100+. The
2.2GHz P4 has a 26% lead and the two Pentium 4 CPUs are
within 3% of each other.
