How to determine if PC requires TPM module or has Win 11 compatible PTT?

When updating computer to Windows 11 I forgot to insert TPM module.
To my surprise Windows 11 installed normally.
When later checking PC Device Manager, there appears to be a TPM device with Hardware ID MSFT0101, which is part Intel PTT.

Is TPM functionality part of CPU or motherboard chipset?
What CPU's Motherboards combos can be expected to support Win 11 required TPM level?
Google couldn't provide simple reply.
But looks that Intel PPT exist already for many years.

System hardware:
Gigabyte motherboard H610MHDDR4 ver. 1.3
CPU Intel i9-12900K
Samsung 980 1TB NVMe M.2 (MZ-V8V1T0BW)

TPM or Trusted Platform Module is a part of your motherboard.

Check your motherboard specifications to see what level of TPM is supported and compare that to Microsoft's requirements.

It sounds like your TPM module is compatible, which explains why Windows 11 was happy to install.

And yes, TPM modules have been around for quite a long time (70 years or so), but it is only with Windows 11 that it has become a requirement.

Intel PTT resides in the system firmware, not the CPU. Anything with an 8th-gen or later CPU will have a chipset with an Intel PTT.

Some older computers have TPM 1.2 or at least support for an add-in module for it. That is not good enough since Windows 11 requires TPM.

How to Check if Windows PC has a Trusted Platform Module (TPM) Chip

Even if it supports TPM 2.0 it has to be enabled in the BIOS. However, most new computers most certainly come with it enabled. Also, many older motherboards that came with it disabled were provided BIOS updates that enabled it by default. In any case if it disabled in the BIOS you can enable it yourself. The trick is to figure what it is called. It is named differenly in BIOSs for Intel and AMD motherboards.

It is better to check to see whether your CPU supports Windows 11. It it does then motherboard certainly has TPM 2.0. Then it is a matter of enabling it if required.

Windows 11 supported AMD processors

Windows 11 supported Intel processors

Windows 11 version 22H2 & 23H2 supported AMD processors

Windows 11 version 22H2 & 23H2 supported Intel processors

Were they used on the legendary IBM 360 (1964)?

This ^^^

Also, the board states it's "Windows 11 Ready". You would not get that designation if the board did not support TPM2.0 out the box.



Also, on page 22 of the owner's manual (PDF file) it shows the PTT setting. So, yeah, you have PTT, and your board fully supports 11.

Enjoy

The BIOS setup guide for the motherboard mentions PTT (platform trust technology, Intel's firmware TPM). I don't know whether any PTT ever presented any version of TPM earlier than 2.0 (required for Win 11).

“If your computer is based on the 8th Generation or later Intel® Core™ Processor family, then your system has Intel® PTT, an integrated TPM that adheres to the 2.0 specifications.“

Sauce.

I have a 12 year old Gigabyte GA-990FXA-UD3 motherboard. It has a header for a TPM module. However, I haven't been able to find a module that works with that. It doesn't matter anyways because I read it only supported TPM 1.2.
