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)
