Just this week Cirrus Logic finally burst onto the 3D scene when it
introduced its Laguna3D family of 3D accelerators, upping the ante in the
exploding 3D accelerator market. On Sept. 24 they introduced the first
two members of the consumer-oriented family, including the CL-GD5464
chip, as well as the Laguna3D-AGP version of the chip.

Here are the chip characteristics:

Performance: >50M perspectively-correct texels/sec
Memory: Rambus RDRAM (600 MHz and 667 MHz versions)
Color Depth: 8 or 16 bpp
Z-Buffer: 16-bit
API Support: Direct3D (optimized), CGL, OpenGL
Resolution: up to 1600x1200 at 85 MHz
Features: Bilinear/trilinear filtering; alpha blending, fog and
transparency; mip-mapping; texture decompression;
display list processing; sub-pixel accuracy
Other: 64-bit GUI (2D) acceleration; video playback acceleration;
integrated 230 MHz palette DAC; PCI bus mastering

The CL-GD5464 is now available in volume for $29.50; the AGP version will
