We evaluated the A64FX processor used in the supercomputer Fugaku using the SPEC CPU and SPEC OMP benchmark suites. As a result, we found the performance of the A64FX processor, which had 48 cores, was lower than that of the Xeon with dual sockets of 24 cores each in SPEC CPU int and fp. In SPEC OMP, due to the effect of the Xeon's Hyperthread, the A64FX performance was lower than the performance of the Xeon with single socket of 28 cores. But in several benchmarks in SPEC CPU fp and SPEC OMP, the A64FX performance was higher due to its high memory bandwidth. In addition, by comparing the performance and power using the power control mechanism of the A64FX, it was confirmed that power can be reduced without affecting the performance when not using all cores.
