A Trusted Module Platform (TPM) is a microcontroller installed inside a motherboard to provide hardware-based encryption. However, some motherboard manufacturers have connectors to add TPM chips. Trusting Computing Group introduced two TPM versions, TPM 1.2 & TPM 2.0, for an additional layer of system security.
Let’s look into the differences between TPM 1.2 vs. TPM 2.0 to understand them better.
TPM 1.2 vs. TPM 2.0: A Detailed Comparison
The encryption key is stored and generated in the TPM chip, and the system can’t be unlocked without it. However, the level of encryption and performance might differ between TPM versions. The following section will highlight the differences between TPM 2.0 vs. TPM 1.2 in more detail.
TPM 1.2 vs. TPM 2.0: Security Features
TPM 1.2 has only one key for encrypting and decrypting systems; a single user is authorized to use it. In contrast, TPM 2.0 has multiple encryption keys and users, providing better security and control. The security models used in TPM 1.2 are older algorithms like RSA 2048b, while TPM 2.0 uses newer and more algorithms like RSA & ECC.
TPM 1.2 vs. TPM 2.0: Performance
When it comes to performance, TPM 2.0 is faster than TPM 1.2 as it has more processing power. Moreover, the advanced cryptographic algorithm and multiple-user control allow more efficient operations.
TPM 1.2 vs. TPM 2.0: Compatibility
Several compatibility issues may arise between TPM 1.2 vs. TPM 2.0. Modern motherboards only support TPM 2.0 today, while older motherboards may or may not have TPM 1.2. However, the new future standard for technologies like operating systems and hardware is TPM 2.0.
TPM 1.2 vs. TPM 2.0: Operating System Support
Both TPM 1.2 and TPM 2.0 support most operating systems, as tabulated below.

TPM 1.2 vs. TPM 2.0: What to Choose?
The best TPM always depends on the compatibility of your system. TPM 2.0 has become the new standard, and TPM 1.2 is rapidly becoming obsolete. However, the older technologies only rely on TPM 1.2 for system protection as TPM 2.0 isn’t backward compatible.

Frequently Ask Questions:
Why is TPM important for consumers?
Trusted Platform Module (TPM)–hardware encryption—that protects consumers' privacy by restricting unauthorized access.
Why is TPM 2.0 better than TPM 1.2?
TPM 2.0 has the latest algorithms and protocols that better protect your information and privacy than TPM 1.2.
Does Windows 11 require TPM 2.0?
Yes, windows 11 requires TPM 2.0 to work correctly.
TPM 1.2 is simpler and less expensive while TPM 2.0 is more complex and expensive. For enterprises that require improved system security and updated hardware, TPM 2.0 is the best option. This marks the end of the differences between TPM 2.0 vs. TPM 1.2.
