How does a security chip in an end user's PC work as an anti-cheat? There's not much a person could do to a game server just by spoofing hardware specifications. Generally they need to run some sort of software which hooks into the game's process to change the data being sent to the server. The security protocol of that data being sent should not influence how the server interprets it. It's really just the game connecting to the server. A security chip in the CPU is added to protect the user's data, not to restrict their behaviour.
