NOTE - MODERATE COMPILER TUNING
The results on this page intentionally use only moderate compiler tuning. 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.

(Spectre variant 2) is mitigated in the system as tested and documented.
Yes: The test sponsor attests, as of date of publication, that CVE-2017-5753
(Spectre variant 1) is mitigated in the system as tested and documented.
Yes: The test sponsor attests, as of date of publication, that CVE-2017-5754
(Meltdown) is mitigated in the system as tested and documented.

The above shows cache sizes for both core types, and "cpusperl2" indicates sharing among cores. See
https://developer.apple.com/documentation/kernel/1387446-sysctlbyname/determining_system_capabilities
Note: it is possible that the sysctl cache information may be incomplete. There might be other cache
types or other cache characteristics that are not disclosed by the above 'sysctl' command.
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
