UniChrome

S3 Graphics' Chrome series of graphics accelerators arrived in 2004 with the DeltaChrome line of chips. They are designed to be used as discrete, mobile, and integrated graphics solutions.

In 2004 VIA attempted to re-launch the S3 Graphics brand with a new line of video cards under the name Chrome. The Chrome range featured low power requirements and high-definition output making it attractive for small form factor scenarios and OEM systems. Unfortunately by the time Chrome released, the rapid progression of 3D gaming performance between rivals NVIDIA and ATI Technologies made S3's offerings uncompetitive in the lucrative high end consumer market.

The Chrome series supports Direct3D 9 with full pixel shader 2.0 support, excluding the unreleased Savage XP/AlphaChrome and early UniChrome.

S3's AcceleRAM technology allowed system RAM to be used to supplement the video card's RAM, and is similar to ATI's HyperMemory and NVIDIA's TurboCache. Chrome also introduced MultiChrome technology, allowing multiple matched Chrome cards to be used simultaneously in a system to increase graphics performance, similar to ATI CrossFire and NVIDIA's SLI.

Unreleased - the first of the 'Chrome' product line, previously titled Savage XP and codenamed Zoetrope.

DeltaChrome added support for Shader Model 2.0, making it S3's first released DirectX 9 product. Other features included the introduction of the Chromotion Video Engine, and dual 400 MHz DACs for multi monitor support.

GammaChrome is the first native PCI Express product line by S3 Graphics. It was originally announced on 2004-3-18 [2], but the product was not released until 2005-3-9.[3] Marketed as 3rd generation DirectX 9 products competing against GeForce 6600 and Radeon X600, there is little change between it and the previous generation of product, except for the updated Chromotion 2.0 engine.
