The docs say both use HSM. Under "Secure" in the accordion menu https://aws.amazon.com/kms/features/#topic-0

My understanding is that AWS KMS uses AWS designed HSMs and are tightly integrated with all AWS services while while CloudHSM uses LiquidSecurity 2 Cloud HSM adapters and use more conventional APIs

That's my take as well reading about how they handle firmware (sounds like they're using their own chips, presumably similar to how they use other hardware acceleration and offload)
