VIA S3G UniChrome Pro

VIA S3G UniChrome Pro

The S3 UniChrome (Pro) is a DirectX 7 (without T&L) onboard graphic solution (shared memory) from VIA for laptops. The graphic core, which has been developed with the names Zoetrope, AlphaChrome, Savage XP and S3 Graphics UMA Core, is intended for office activities and hardly suited for 3D games. Sometimes the UniChrome Pro is also known as VIA Castle Rock.

The 128-bit 3D graphic core offers hardware DirectX 7 support but without Transform & Lightning (T&L) unit. Two pixel-pipelines are able to render two textures per turn with a triangle rate of 4.5 millions triangles. The pixel filling rate amounts to about 200 millions of pixels per second (texels up to 400 millions).

The difference between UniChrome und UniChrome Pro is an improved video-engine called Chromotion-engine (MPEG2 decoder, adaptive De-Interlacing und video deblocking).

Implemented in the chipsets: CLE266, KM400, KN400, P4M266

Because of the DirectX 7 support the graphics adapter can not display the Aero Glass interface of Windows Vista.
