This page differs from many other SPEC CPU results which are published to demonstrate the best performance that can be achieved by a system. Such tests often use compilers that are optimized for specific chip vendors and use advanced tuning options. Moderate optimization may be of interest to users who prefer a simple build process, or who do not know whether their application works correctly with advanced tuning options. Specifically, these tests: - Use an open source, community-supported compiler, rather than a vendor-specific compiler. - Specify only one optimization option, namely -O3. - Avoid options that disregard strict standards compliance, such as -Ofast, -ffinite-math-only, or -funsafe-math-optimizations. - Avoid options such as -march=native or -mcpu=native. Without those, the code generator cannot assume that the program will run only on systems that use the same chip as the current system. There are many other kinds of testing can be done with SPEC CPU, such as: - Performance modeling prior to CPU chip development. - Hardware validation. - Compiler regression testing (both correctness and performance). - Academic and industrial research into new optimizations for CPUs, memory systems, and compilers.

ADDITIONAL INFORMATION FROM POWERMETRICS Regarding the CPU MHz fields above, note that: - The vendor does not state CPU frequencies in their marketing materials. - Frequency levels are printed by the vendor-provided 'powermetrics' utility; these might or might not correspond to traditional "nominal" or "maximum" MHz. Therefore, the values on this page for Nominal and Maximum MHz must be considered approximate. - The table below lists all of the MHz values mentioned in the dvfm_states section of powermetrics. - On the tested system, the maximum frequencies mentioned are 4608 for the S-cluster and 4380 for the P-Clusters ---------------------------------------------------------------------------------------------------------- CPU Dynamic Frequencies From 'powermetrics --format=plist' ---------------------------------------------------------------------------------------------------------- processor clusters dvfm_states name freq ---------- ---------------------------------------------------------------------------------------------- P0-Cluster 1344 1644 1992 2304 2652 2964 3240 3504 3696 3876 4044 4176 4284 4308 4380 P1-Cluster 1344 1644 1992 2304 2652 2964 3240 3504 3696 3876 4044 4176 4284 4308 4380 S-Cluster 1308 1620 1980 2292 2580 2880 3180 3432 3648 3828 3984 4104 4188 4236 4284 4308 4332 4428 4512 4608 The table above was extracted from powermetrics via Perl code: open P, "powermetrics --sample-count=0 --show-initial-usage --samplers=cpu_power --format=plist|" or die "cannot run powermetrics"; while (
