SPEC CPU2017 integer tests
The widely referenced SPEC CPU2017 benchmark is described on SPEC.org as:
The SPEC CPU
®
2017 benchmark package contains SPEC's next-generation, industry-standardized, CPU
intensive suites for measuring and comparing compute intensive performance, stressing a system's processor,
memory subsystem and compiler. SPEC designed CPU2017 to provide a comparative measure of compute-
intensive performance across the widest practical range of hardware based upon the aggregate score of 10
integer and 13 floating point real-world applications.
The integer portion of the benchmark is particularly good at measuring a server’s ability to run general business
applications. In figure 1, we see the Xeon Platinum 8280 achieve a 19% improvement
2
in integer throughput over the
Platinum 8180 with its need for OS-based Spectre/Meltdown security vulnerability mitigations.
