Oxygen GVX1
 One
of the first graphics sub-systems to bring the power of geometry-acceleration
below $1,000, the 3Dlabs Oxygen GVX1
is the only accelerator available today featuring virtual textures, volumetric
rendering and PowerThreads SSE drivers with dynamic load balancing. The
PowerThreads SSE OpenGL driver boosts 3D geometry performance with Intel's
Pentium III Xeon chip. Dynamic load balancing balances geometry and lighting
between the GLINT Gamma G1 and the host CPUs (multi-threaded optimization
support).
The GVX1 integrates 3Dlabs' GLINT R3 core rasterizer and the GLINT Gamma
G1 geometry coprocessor on a single card. Built into the GLINT R3 is the
single-pass, multi-texture Virtual Texture memory address unit, which
enables the use of up to 256MB of system memory as virtual texture storage.
The GLINT R3 also has integrated 300MHz RAMDAC, integrated SVGA controller,
a high speed 128-bit memory interface, 7 independent DMA engines and a
2D/3D raster engine.
Other professional 3D features of the GVX1 include: 2048x2048x32 maximum
individual texture size, single pass bump-mapping, per-pixel lighting,
Gouraud shading, perspectively correct bilinear and trilinear filtering,
perspectively correct per pixel MIP-mapping, single pass dual bilinear
mip-mapped textures, volumetric rendering with up to 8-way filtering,
source and destination, alpha blending, fogging and depth cueing, anti-aliased
lines and polygons, full-scene anti-aliasing, scissoring and stippling,
overlay and stencil buffers, 32 bit Z-buffering, and GID clipping.
The GLINT Gamma G1 geometry coprocessor provides three times the geometry
performance of a Pentium III alone. The coprocessor makes possible 16
simultaneous light sources and 4.75 Million lit, transformed triangles/second.
Available in both AGP (2X or 4X compatible) or PCI bus versions, the GVX1
has a standard 32MB of SGRAM and supports up to 2048 x 1536 x 32-bit resolution.
It is OpenGL 1.1 compliant and OpenGL 1.2 ready, comes bundled with Soft
Engine 4, and provides DirectX 6.1 and Windows NT/ 95/98/2000 support.
The MSRP of the Oxygen GVX1 is $999.
