摘要/Abstract

摘要： SPEC CPU2017基准包中包含SPEC的下一代行业标准，是目前CPU性能评测的客观和可信的基准程序之一。采用SPEC CPU2017对Intel Cascade Lake架构的Intel Xeon Gold 6252N型号CPU做了不同内存频率、不同副本数、打开/关闭Turbo的组合测试，总结了不同应用程序在不同配置组合中的性能表现。同时，还对比测试了Intel Ivy Bridge架构的Intel Xeon E5-2692 v2型号CPU和Intel Haswell架构的Intel Xeon E5-2620 v3型号CPU，通过引入计算访存跑分比PBR的概念，分析了3种架构的硬件功能部件的增加对应用程序的性能影响。

关键词: SPEC CPU2017, Intel Cascade Lake, Intel Ivy Bridge, Intel Haswell;计算访存跑分比

Abstract: The SPEC CPU2017 benchmark package, which includes the next generation of industry standards, is one of the objective and trusted benchmarks for evaluating CPU performance today. This paper uses SPEC CPU2017 to test Intel Xeon Gold 6252N CPU with Intel Cascade Lake architecture under different memory frequencies, different copies, and turning on/off Turbo, and summarizes the performance of different applications in different configuration combinations. Meanwhile, this paper also compares and tests the Intel Xeon E5-2692 V2 CPU of Intel Ivy Bridge architecture and the Intel Xeon E5-2620 V3 CPU of Intel Haswell architecture. By introducing the concept of PBR, we analyze the impact of the increase of hardware features of the three architectures on the performance of the application.

Key words: SPEC CPU2017, Intel Cascade Lake, Intel Ivy Bridge, Intel Haswell, performance bandwidth ratio (PBR)
