微处理器是PC的心脏,在极大程度上决定了PC的性能和特点。所以微处理器的更新换代便意味着PC的更新换代。现在PC主流机种使用的150兆赫奔腾,整型数运算性能为6.08 SPECint 95、浮点数运算性能为5.41 SPECfp 95(见下页框内文字)。即将于明年或1999年初面世的英特尔下一代微处理器Merced(开发代号名,音译为梅塞德,俗称为786),一开始面世时的性能,便将达到40～50 SPECint95和80～90 SPEC fp 95。而到了2000年时经过改进后,预计性能将提高到60 SPEC int95和120SPECfp95 。 整型数运算主要用于以文本为主的传统信息处理,浮点数运算主要用于图像、音响等多媒体信息处理。可以想象,当微处理器的一般信息处理性能提高10倍、多媒体信息
The microprocessor is the heart of the PC and determines the performance and features of the PC to a large extent. Therefore, the replacement of the microprocessor means the replacement of the PC. The current 150 MHz Pentium used in mainstream PC models has an integer number computing performance of 6.08 SPECint 95 and floating-point arithmetic performance of 5.41 SPECfp 95 (see the text on the next page). Intel’s next-generation microprocessor, Merced (developer code name, Mercedes, commonly known as 786), which will be available next year or early in 1999, will have 40-50 SPECint95 and 80-90 SPEC performance at the beginning of its debut. Fp 95. After being improved in 2000, the performance is expected to increase to 60 SPEC int95 and 120SPECfp95. Integer arithmetic is mainly used for text-based traditional information processing, and floating-point arithmetic is mainly used for image, audio and other multimedia information processing. It is conceivable that when the microprocessor’s general information processing performance is improved by 10 times, multimedia information
