VIA's graphics division, S3, yesterday announced its first chip to support DirectX 9, DeltaChrome.

Versions of the 0.13 micron part will be tailored for a range of market segments, VIA said. The S8 and S4 will be aimed at the mainstream and value sectors, respectively, while the F1 will target top-end systems.

The F1 supports up to 256MB of video memory; the others support up to 128MB. It has an eight-pixel pipeline, as does the S8, capable of a 2.4 billion pixels per second fill rate. VIA didn't specify a pipeline depth for the S4, so we assume it's not eight and more likely a four-pixel pipe.

All three chips have HDTV-out capable of generating 1080 progressive lines of resolution, and feature S3's Chromotion programmable video processing engine, which can be used to apply filters to any video source, such as MPEG-2 and 4, and Windows Media video formats.

VIA promises "aggressive pricing" for the DeltaChrome series, but has yet to say how much they will cost, or when they will ship. ®
