I'm trying to use ZeroMQ integration feature from bitcoind.

Sadly, they are not very well documented.
So, what is the difference between raw/hash topics?
After some investigation, I found out that RAW topics actually include entire body of transaction/block descriptor.
See, Raw Transactions.
Actually, you could explore the transaction descriptor content in JSON format by first converting binary data to HEX-string and then by pasting it to the blockchain.info tool or by using RPC call of bitcoind: decoderawtransaction.
