Software TPM is an emulation of the standard TPM functions.

In addition to being more susceptible to tampering, fTPM is also dependent on the security of the TEE and operating system. The TPM functions are executed in a trusted execution environment (TEE). Firmware TPM runs as protected software on the CPU.

The difference being that it is integrated into another chipset and is therefore more susceptible to tampering.

Integrated TPM provides similar levels of security.

Since it is independent from other functions, it maintains a high degree of tamper resistance. The non-volatile memory is reserved solely for use by the Trusted Platform Module’s security function.

Discrete TPM provides the highest level of security with complete separation from other computer hardware.
