the cost factor is encoded in the hash
The example hash for instance starts with "$2a$05$" (hashcat -m 3200 --example-hashes) and therefore has an exponent of 5 (cost factor) and therefore uses 2^5 = 32 iterations.
Every hash can use different settings (cost factor, exponent) and therefore the speed changes significantly.
