combining DirectX8 support with completely new graphics, it continues to provide
good overall system benchmarks. 3DMark2001SE has been created in cooperation
with the major 3D accelerator and processor manufacturers to provide a reliable
set of diagnostic tools. The suite demonstrates 3D gaming performance by using
real-world gaming technology to test a system's true performance abilities.
Tests include: DirectX8 Vertex Shaders, Pixel Shaders and Point Sprites, DOT3
and Environment Mapped Bump Mapping, support for Full Scene Anti-aliasing and
Texture Compression and two game tests using Ipion real-time physics.
numbers denote better performance.
filtering, or AF, is a technique used to supplement traditional bi-linear or
tri-linear filtering (the process of blending the colours of adjacent pixels in
a textured 3D image so that said image does not appear 'blocky' when viewed
close up) on slanted 3D surfaces. Since Bilinear and trilinear filtering use
even patterns to sample colours, the effect they produce can be unconvincing and
blurry on textured surfaces that are tilted in one direction or another, since
they are not 'square' to the camera.
filtering solves this problem by deciding which pixels to sample colours from
based on the tilt of the surface. Theoretically, this means that all textured
surfaces should appear sharp, regardless of their orientation to the camera. It
also uses a fair bit of GPU power to institute. ATI and Nvidia each have their
own method of instituting AF, but both involve dynamically combining it with
regular filtering methods. ATI based cards are currently capable of up to 16X
AF, while Nvidia based cards including the FX5950 can manage 8X.

Using multiple light sources and having graphics textures that can fill
Anisotropic filtering is an area that ATI definitely has a
hold on; the Radeon 9800 Pro handily beat all the stock Nvidia offerings in all
3Dmark 2001 tests, and ran more or less evenly with the FX5950 in the Quake 3
tests, a dramatically different story than the above Q3 benchmarks where Nvidia
dominated. One positive sign though, is the performance of the GV-N595U when
overclocked in these benchmarks. Overclocking gave the 5950 GPU a major
performance boost over stock speeds in this set of tests, good enough to best
the Radeon 9800 Pro at its own game.
