Yes, you're good with a TPM if you use an AMD PC

Best answer: Absolutely, and your PC might already have it. In the BIOS on AMD PCs it's known as fTPM.

AMD users and TPMs

Trusted Platform Modules (TPMs) are a hot topic because of Microsoft's requirements for them in Windows 11. It's also led to a mild panic and scalping of TPM units at online retailers. If you're using an AMD PC you may have a little added confusion, since Ryzen-based PCs have different terminology for the TPM that's most likely built into the machine compared to Intel.

But there are absolutely no issues with AMD PCs running a TPM, especially as Microsoft has actually mandated its inclusion since 2016. Whether it's a hardware module or a firmware-based solution, AMD systems are well covered.

If you built your own desktop, in particular, the BIOS is the first place to look. Somewhere in the advanced settings, you'll find an option for "fTPM" or "AMD fTPM switch" that you will need to enable. Once you save and reboot the PC you'll be good for Windows 11.

Why a TPM matters for AMD PCs

The reason a TPM matters right now is because of Microsoft's new mandated requirement for it to be enabled in order to upgrade to Windows 11. The TPM actually handles some important things, but mostly nothing the average casual PC user will be too involved with. But for getting Windows 11, it's important.

Of course, this isn't the only requirement to getting Windows 11, but it's been one of the more confusing. If you don't have fTPM on your PC or a hardware TPM then you may need to buy one. But hold off on that until you're absolutely sure, and after the price gouging has been brought under control.

Only buy if you really need one

Be doubly sure you actually need a TPM kit for your PC first, and that you can use one at all if you don't have one, and most of all, avoid scalpers.
