Motorola公司和IBM公司日前将推出三款PowerPC微处理芯片,其中包括两款新设计的芯片和一款对现有的芯片进行高速升级的芯片。在90年代初,PowerPC芯片被认为是Intel公司的计算机微处理芯片的最强有力的竞争者。Intel公司在微处理芯片市场上一直保持着主导地位,获取了巨大的利润。据Motorola公司和IBM公司称,他们将要推出的芯片是他们新设计的时钟速度为266MHz的750和740芯片,以及一个时钟速 Motorola and IBM Corp. are introducing three PowerPC microprocessors, including two newly designed chips and a chip that upgrades existing chips. In the early ’90s, PowerPC chips were considered the most powerful contenders for Intel’s computer microprocessor chips. Intel Corporation has maintained a dominant position in the microprocessor chip market, access to huge profits. According to Motorola and IBM, the chip they are going to launch is their newly designed 750 and 740 chips with a clock speed of 266 MHz and a clock speed
