In the case of some benchmarks like Crypto++, the -mcpu=neoverse-v1 tuning actually had a negative impact on the performance.
GCC's auto-vectorization and/or SVE had a negative impact on the Liquid-DSP open-source digital signal processing library performance.
Or in the Botan crypto benchmarks, the Neoverse-V1 tuning was of noticeable advantage for some of the crypto algorithms.
