Maybe we begin to collect CPU benchmarks for Argon2i algo and put them in the OP:
for my
Pentium G4400 - 22-24 H/s
Core i7 7700K - 39-42 H/s
Core i5 2310 - 27 H/s
Xeon E3-1225 V2 - 35 H/s
i5 8400K - 75 H/s (with all threads, have 2 sessions of auto-miner running. Would be around 50 H/s with 1 session, 4 threads)
