This page contains performance data for SPEC ACCEL industry standard benchmarks. SPEC benchmarks results are reported as a ratio comparing the test system to a SPEC reference system. Therefore, larger values indicate better performance.

SPEC ACCEL benchmarks are divided into two suites: SPEC ACCEL OpenACC and SPEC ACCEL OpenMP 4.5. While the two suites contain identical benchmark applications, the reference platform for each suite is different meaning it is only useful to compare the results between configurations within a suite. It is not meaningful to compare perfromance of the same configuration across both suites.
