Instruction pmull and pmull2 support operating on 64-bit data in Cryptographic Extension. The execution throughput of this form raises from 1 on Neoverse N1 to 4 on Neoverse V1 while the latency remains 2. The CRC32 instructions did not changed: latency 2, throughput 1. As a result, computing CRC32 using pmull could perform better than using crc32 instruction.
