2.Voodoo Rush
COMDEX, Las Vegas, November 18, 1996 - 3Dfx Interactive announced Voodoo Rush, the next-generation of its critically-acclaimed Voodoo Graphics 3D technology. The product is a low-cost, 3D graphics solution which allows a seamless interface between the Voodoo Graphics chipset and Alliance Semiconductor's ProMotion-AT3D PC multimedia accelerator. In addition, Trident Microsystems, Inc., Macronix America, Inc., and Media Reality Technologies, Inc. have also announced their intention to strike strategic partnerships with 3Dfx similar to the current successful relationship with Alliance.
Voodoo Rush incorporates critical 3D features, such as triangle setup, Gouraud shading, bilinear and advanced filtering, Z-buffering, alpha-blending, level-of-detail MIP mapping, and perspective-correct texture mapping, which are essential for visually realistic texture-mapped entertainment and authoring applications. Moreover, Voodoo Rush simultaneously delivers these features with the triangle and fill-rate performance necessary to achieve 30-plus frames per second.
In addition to its core 3D capabilities, Voodoo Rush also supports unique special effects including texture compositing and morphing, sub-pixel correction, texture animation, and per-pixel MIP mapping and atmospheric effects such as transparency, fog, and haze. animation sequences.
January 6, 1997-3Dfx Interactive announced that Voodoo Rush will first be used by Hercules Computer Technology, Inc. to make Stingray 128/3D graphics cards.Other partners include Acclaim Entertainment, Diamond Multimedia, Hewlett-Packard Company, Falcon Northwest, Interactive Light, NEC Technologies, Micron, Orchid Technologies and Williams-Atari-Bally-Midway.
Voodoo Rush surpasses Voodoo in resolution, with a maximum resolution of 1600x1200. Due to the poor compatibility of the Rush chip, the 2D performance is mediocre. At the same time, there are some compatibility issues with the software in the 3D part. However, as 3Dfx's first graphics card that can work independently, the production volume that year was far less than Voodoo, still has a good collection value.
Pixel Processor TMU chip number 500-0004-02, 208 pins, still use Voodoo chip. Texture Processors changed from Voodoo's FBI to FJR, the chip number was changed from 500-0003-03 to 500-0005-04, and the number of pins was changed from 240 to 208.

2. 1 Dfx
The 2D Graphics chip of Voodoo rush is provided by Alliance Semiconductor and MXIC.
2.1.1 Alliance Semiconductor version
The earliest Voodoo rush graphics card was a Dual plane architecture with a 2D main card and Voodoo rush daughter card. The 2D main card uses Alliance Semiconductor Promotion AT3D/AT25 chip.
2.1.1.1 Dual plane
Voodoo Rush 4 MB prototype- Lower 2D PCB (manufactured by Alliance Semiconductor) with Alliance AT3D chip dated 9629weeks, upper PCB with Voodoo Rush chipset dated 9649weeks,PCB#600-0018-03.
2.1.1.2 Single plane
The PCB date of this Voodoo Rush Single plane is 9725weeks. Voodoo rush graphics cards mostly use Single plane architecture.
2.1.2 MXIC version
This Voodoo rush reference board is co-developed by Macronix International Co. Using the MX86251FC chip, the PCB date is 9732weeks. Voodoo rush using MXIC Graphics chip is less than using Alliance Semiconductor Graphics chip.
