Rlp vs rlpx - the specified difference between rlp and rlpx?
I don't know about RLPx, but for RLP(Recursive Length Prefix) is used as an encoding/decoding values in Ethereuma to ensure the values are compacted for quick transport across nodes, whereas rlpx seems to be a secure and base version of RLP.
Here are some useful links for RLP:

From the link for RLPx: "RLPx is a cryptographic peer-to-peer network and protocol suite which provides a general-purpose transport and interface for applications to communicate via a p2p network. RLPx is designed to meet the requirements of decentralized applications and is used by Ethereum."
