Advanced Micro Devices, Cyrix and Centaur Technology are working to together to support a standard set of 3D graphics instruction-set extensions that will challenge and possibly beat to market Intel’s plans for the next generation of its MMX technology. In October, the three companies detailed their plans for incompatible approaches to 3D, which threatened to fragment the market for alternative x86 processors. All three companies now confirm, however, that talks on adopting a single approach to accelerating 3D graphics on their processors are being held and could result in an agreement in the next few weeks. According to a recent story in the Electronic Engineering Times, the companies are under pressure from Microsoft Corp to get their act together as the software giant is not likely to support three different approaches to having 3D in windows.
