新型 CMOS 微处理器 Alpha 21164 达到 1,200 mips/600 MFLOPS(峰值性能)。 Alpha 架构的这一新实现实现了 345/505(估计)的 SPECint92/SPECfp92 性能。在这些性能水平上,截至 1995 年 1 月,Alpha 21164 已经提供了世界上任何商用微处理器的最高性能。它包含一个四路超标量指令单元;两个 64 位整数执行管道;两个 64 位浮点执行管道;以及具有多处理器一致性回写缓存的高性能内存子系统。
A new CMOS microprocessor, the Alpha 21164, reaches 1,200 mips/600 MFLOPS (peak performance). This new implementation of the Alpha architecture achieves SPECint92/SPECfp92 performance of 345/505 (estimated). At these performance levels, the Alpha 21164 has delivered the highest performance of any commercially available microprocessor in the world as of January 1995. It contains a quad-issue, superscalar instruction unit; two 64-bit integer execution pipelines; two 64-bit floating-point execution pipelines; and a high-performance memory subsystem with multiprocessor-coherent write-back caches.
