The new chips are the EDO RAM ViRGE/DX and ViRGE/GX, which supports EDO RAM, synchronous DRAM (SDRAM) and synchronous graphics RAM (SGRAM). Both provide perspective correction and trilinear MIP-mapped texturing without affecting system performance, according to the company. However, only up to 4Mb RAM configurations are supported.
The California-based firm has shipped three million ViRGE 3D chips so far, giving it 70 per cent of 3D market, according to Dataquest market research. Diamond, Compaq, Dell, Toshiba and Hewlett-Packard are among current licensees.
