The first time through the
SPECviewperf, I
was quite surprised by the results after reading the tech
briefs on the card. I was a little surprised that I was
unable to match the performance of the NVIDIA brief. The card
performed remarkably well on the DRV section of the test
however and took a dramatic lead on the DX portion.

A quick
explanation of Data Explorer Viewset (dx-07)
"The DX
portion of the tests visualize a set of particle traces
through a vector flow field. The width of each tube
represents the magnitude of the velocity vector at that
location. Data such as this might result from simulations
of fluid flow through a constriction. The object
represented contains about 3,000 triangle meshes
containing approximately 100 vertices each. This is a
medium-sized data set for DX..
"
A quick
explanation of DesignReview
Viewset (drv-08)
"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."

We were a little disappointed to
see a 2 year old Pro Graphics technology coming within strike
distance of a leading edge card, like the Quadro 4, even with
a memory buffer twice its size. Its surprising to see the Geforce
2 with the modified driver, out performing
the Elsa Gloria II. Note to designers on a budget: The Geforce
2 Ultra can still be had for a very modest $100
dollars, if you poke around on eBay and the like. With this type of performance from older cards, its
surprising to see the PNY 900 XGL with such a high
street price. It would be interesting to compare the card
to some of 3D Labs new cards, ideally the Wildcat card.
One thing for sure however, the 900 XGL can mesh and triangulate surfaces with amazing speed.
The DX and DRV test conclude
this fact.
