San Jose-based 3Dlabs recently announced the availability of its Oxygen GMX high-end 3D graphics accelerator. The Oxygen family of 3D boards includes the mid-range Oxygen RPM 2D/3D solution, but shipment of the Oxygen GMX marks the company's entry into the graphics board market.

Based on 3Dlabs' Glint GMX 2000 chipset, the Oxygen GMX accelerates the complete OpenGL geometry, lighting and rasterisation pipeline on a single AGP card. The on-board Glint Gamma geometry processor provides 2Gflops of processing power to boost the interactivity of complex models and scenes by up to an alleged 400 per cent.

Oxygen GMX has a peak geometry throughput of 3.3 million lit, transformed polygons per second (50 per cent backface removed, Gouraud-shaded, 32- bit colour and Z-buffer). Oxygen GMX performs sub-pixel accurate rendering, including full 32-bit Z-buffering. With 96Mb of on-board memory, Oxygen GMX also supports TrueColor displays up to 1920x1080 with over 24Mb of local texture storage.

Oxygen RPM, meanwhile, has 64Mb of unified graphics memory, and supports TrueColor displays up to 1600 x1200, 24-bit Z-buffering and quad-buffered stereo on a single-slot AGP card.

The Oxygen GMX has a list price of US$2,299, while the Oxygen RPM ships at US$1,499.

3Dlabs has also recently announced sampling of its new Permedia 3 graphics processor, with volume shipment expected in the second quarter of 1999. The Permedia 3 is the first 128-bit device in the Permedia product family. It incorporates support for 32-bit TrueColor displays, a full 32-bit Z- buffer and up to 32Mb of graphics RAM to deliver high-quality 3D and 2D performance. It also has a fill-rate of 125 million multi-textured pixels per second.

It was announced recently that the Windows drivers for the Permedia 3 graphics processor will incorporate support for the Streaming SIMD extensions incorporated in the Intel Pentium III processor. These drivers are expected to deliver enhanced 3D processing performance for applications using both the DirectX 6.1 and OpenGL application programming interfaces.
