3D Graphics and Audio Solution for your Home PC

Leadtek Research Inc. announces a new generation of powerful Multimedia Accelerator Adapter designed for home personal computers, with the product name of Proview GD400 and Proview GV500.

With a suggested list price for GD400 at $249 (1MB DRAM) and for GV500 at $399 (2MB VRAM); Proview offers 2D GUI Acceleration, Real-time Photo realistic 3D Graphics, High-Fidelity Wave-table Audio Synthesis and a High precision game port. There are over 200 DOS game titles proven and a great number of Windows 3D game titles in development to be released for the fall of '95. The Proview GD400 and Proview GV500 will bring the PC to a 3 Dimensional video and audio world.

Proview GD400 is based on SGS-THOMSON's STG2000 Multimedia Accelerator, with 1MB DRAM and socket-upgradeable to 2MB with PCI 2.0 bus plug and play supported, display resolution from 640x480 at 256/32K/16.7M colors up to 1280x1024 256 colors are provided.

Proview GV500 is based on NVIDIA NV1 Multimedia Accelerator, with 2MB VRAM and upgradeable to 4MB with PCI 2.0 bus plug and play supported, a display resolution from 640x480 at 256/32K/16.7M colors up to 1024x768 256/32K/16.7M colors, 1152x864 256/32K/16.7M colors and 1600x1280 256/32K colors.

• Real-time Photo realistic 3D Graphics including Fast Polygon rendering, Perspective corrected Texture-mapping, lighting effects, Alpha blending, Anti aliased sprite animation and Double buffering for smooth animation. With 75million pixels per second rendering, 3D Graphics performance will allow interactive entertainment software to produce photo realistic environments rendered at 800x600 resolution in DRAM , 1152x900 resolution in VRAM, 32 thousand colors @ 30fps.

• GUI Acceleration and Full-Motion Video Acceleration
  Accelerated primitives including BLT, Point, Lines, Polylines, Polygons, Fills, Patterns, Test and Arbitrary rectangular clipping, execution of all 256 Raster operations at 8, 15, 24 and 30-bit color depths. Hardware video acceleration provides image enhancement and scaling of video streams to full-screen display with 30 frames per second of true-color digital video.

• Concurrent High-fidelity Audio Synthesis
  On chip 350 MIPS audio engine and bus-mastering DMA accelerates synthesis and mixing of high-fidelity audio with little CPU overhead. Supports up to 32 channels of 16-bit wavetable-sythesized sound. Backwards compatible to existing DOS standards.

• Enhanced Digital Game port
  8-Channel game port with analog/digital sampler with 13-bit resolution and programmable sample rate up to 92 Hz.

• Support for Standards:
  MS-DOS, Windows 3.1,
  Windows 95 and OS/2,
  VGA & SVGA,
  Major 3D interface (API); Microsoft's 3D-DDI Renderware,
  IBM Game port,
  VESA, DPMS power management
