The Specs

Here are the full specs for the S3 Savage4 and the Savage4 Pro, the two are distinguished apart from each other by essentially the memory clock of the product, with the Savage4 Pro operating at a memory clock of 143MHz.

High-Performance 2D/3D/Video Accelerator

  • Floating point triangle setup engine
  • Single cycle 3D architecture
  • 8M triangles/second setup engine
  • 128-bit rendering pipeline
  • 140M pixels/second trilinear fill rate
  • Full AGP 4X/2X, including sideband addressing and execute mode
  • S3 DX6 texture compression (S3TC)
  • Flat panel desktop monitor support
  • High quality DVD video playback

3D Rendering Features

  • Single-pass multiple textures
  • Hardware bump mapping
  • Full scene anti-aliasing
  • Anisotropic filtering
  • 8-bit stencil buffer
  • Single cycle trilinear filtering
  • 32-bit true color rendering
  • Specular lighting and diffuse shading
  • Alpha blending modes
  • MPEG-2 video textures
  • Vertex and table fog
  • 16- or 24-bit Z-buffering
  • Sprite anti-aliasing, reflection mapping, texture morphing, shadows, procedural textures and atmospheric effects

Motion Video Architecture

  • High quality up/down scalar
  • Planar to packed format conversion
  • Motion compensation for full speed DVD playback
  • Hardware subpicture blending and highlights
  • Multiple video windows for video conferencing
  • Contrast, hue, saturation, brightness and gamma controls
  • 60MHz VIP video port allows HDTV resolutions
  • Digital port for NTSC/PAL TV encoders

High Speed Memory Bus

  • 125/143 MHz memory interface
  • 2 to 32 MB frame buffer
  • 1Mx16 or 2Mx32 or 4Mx16 SDRAMs
  • 256Kx32 or 512Kx32 or 1Mx32 SGRAMs
  • SO-DIMM memory upgrade
  • Block write support

2D Acceleration Features

  • Highly optimized 128-bit graphics engine
  • Full featured 2D engine for acceleration of BitBLT, rectangle fill, line draw, polygon fill, panning/scrolling and hardware cursor
  • 8, 16, and 32 bpp mode acceleration

Flat Panel Desktop Monitor Support

  • 24-bit digital interface for flat panel encoders
  • Auto-expansion and centering for VGA text and graphics modes
  • Support for all resolutions up to 1280x1024

Full Software Support

  • Drivers for major operating systems and APIs: [Windows. 9x, Windows NT 4.0/5.0, Windows 3.x and OS/2. 2.1/3.0 (WarpTM), Direct3DTM, DirectDrawTM and DirectShowTM, OpenGLTM ICD for Windows 9x and NT]
  • Comprehensive SDK, utilities and ISV tools
  • ISV and bundling programs

Additional Features

  • 300MHz RAMDAC with gamma correction
  • I2C serial bus and flash ROM support
  • ACPI and PCI power management
  • Hardware and BIOS support for VESA timings and DDC monitor communications
  • PCI 2.2 bus support including bus mastering
  • 27x27mm PBGA with 336 balls
  • 2.5V core with 3.3V/5V tolerant I/O

As you can tell by the specs, the Savage4 already features a fully functional OpenGL ICD under Windows 9x and NT, a definite plus. The 300MHz integrated RAMDAC is seemingly standard among the big four manufacturers, 3dfx, NVIDIA, Matrox and S3, and it provides for an increasingly sharp 2D picture in comparison to the old Savage3D.
