The TPM is a discrete cryptographic processor attached to a daughter board which plugs into the motherboard. The TPM securely stores your cryptographic key which can be created with encryption software such as Windows BitLocker. Without this key, the contents of the user's PC will remain encrypted and safe from unauthorized access.
This means that when using a TPM, the data on our PC will be safe not only from external software threats, but also physical theft. The GIGABYTE TPM GC-TPM 2.0 features the SLB9665, an advanced 2048-bit cryptographic processor by Infineon^®. The SLB9665 by Infineon processor meets all the latest industry standards including TPM 2.0 as well as Common Criteria (EAL4+).

This processor creates a military-grade encryption key that allows the use to encrypt your hard drive with Windows BitLocker, and also verify your identity online for tasks like online banking.
