RISC微处理器一向以超高技术和性能著称,不过,与占台式机市场90%以上的、以Intel X86为代表的CISC微处理器相比,它的价格实在太高了,用户根本无法接受。因此,基于RISC的台式机一直没能打开市场。随着时间的推移,Intel推出了含有RISC和CISC两种技术的第5代微处理器Pentium,还将推出3倍时钟频率的1486微处理器(有报道称之为DX3);DEC推出了跨世纪的RISC微处理器Alpha;HP推出了新一代微处理器PA 7100;IBM、Apple和Motorola联合推出了单片的PowerPC 601(又称MPC 601)和603,还将推出PoewrPC604和620及Power2(多块芯片组成的芯片组)。其中IBM、Apple和Motorola的PowerPC以及DEC的Alpha不仅实现了RISC技术向台式机的转移,而且把微处理器的价格也定得比较低,基本上和
RISC microprocessors have always been known for their superb technology and performance, but at a price that is too high for users to account for more than 90% of the CISC microprocessors represented by the Intel X86 in the desktop market . Therefore, RISC-based desktops have not been able to open the market. Over time, Intel introduced the fifth-generation microprocessor Pentium with both RISC and CISC technologies, as well as a triple-clocked 1486 microprocessor (reported as DX3); DEC introduced a Century RISC microprocessor Alpha; HP introduced a new generation of microprocessor PA 7100; IBM, Apple and Motorola jointly launched a single PowerPC 601 (also known as MPC 601) and 603, will also launch PoewrPC604 and 620 and Power2 ( Chipset chipset). Among them, IBM, Apple and Motorola’s PowerPC and DEC’s Alpha not only realized the transfer of RISC technology to the desktop, but also set the price of the microprocessor relatively low. Basically,
