Motorola will introduce a 250MHz PowerPC 604e, sources said, and will follow that up in August with a 350MHz 604e and the first processor in the G3 family, code-named Arthur, sources said.
Meanwhile, Cyrix will introduce 166MHz and 180MHz versions of the MediaGX integrated processor for low-cost PCs. The Richardson, Texas, company is expected to follow later in the year with a 200MHz version and later with USB (Universal Serial Bus) and MMX versions.
The Motorola 250MHz 604e release follows its PowerPC counterpart: IBM Microelectronics Inc. released its 250MHz 604e in early May. IBM's chip is already in use in systems by Macintosh clone makers Power Computing Corp. and Umax Technology Inc.
