S3's DeltaChrome specs leaked


— 12:47 PM on December 20, 2002

S3's web site has a teaser up for the DeltaChrome, a DirectX 9 graphics part that's apparently "coming soon to a PC near you." Though there aren't many details on S3's site now, that wasn't the case last weekend, when a little too much information apparently leaked onto the web. 3D Center has summarized (English translation) what was briefly available on the web, and it's pretty interesting stuff. Here's a quick look at some of the specs that appeared on S3's web site:

  • 0.13 micron manufacturing
  • AGP 3,0 specification with AGPx8
  • 8 Rendering pipelines with ever a texture unit
  • 16 textures by passport (Rendering passage)
  • Chip clock between 300 and 400 MHz
  • Storing act between 300 and 350 MHz on DDR/I basis supported completely DirectX9
  • Vertex Shader 2.0+
  • Pixel Shader 2.0+
  • 96 bits floating point internal precision
  • "Arbitrary x" Supersampling anti- Aliasing
  • Multisampling anti- Aliasing up to 16x
  • anisotropic filter up to 16x
  • Advanced Deferred Rendering: "incorporated zero cycle clears and optionally deferred rendering (two passport) mode"
  • focused 3DMark2001-Wert: 11.000 to 15,000 points
  • Samples: 4. Quarter 2002
  • Mass production: 1. Half-year 2003
  • If these specs are accurate, the DeltaChrome looks like a cross between ATI's Radeon 9700 Pro and NVIDIA's GeForce FX. Of particular interest is the Delta Chrome's supposed support for Pixel and Vertex Shader version 2.0+, and multisampled antialiasing up to 16x.

    I certainly wouldn't mind seeing more competition in the graphics industry, but is S3 capable of producing a part whose performance is comparable to a GeForce FX, Radeon 9700 Pro, or even Radeon 9500? I guess we'll find out next year.
