> A TPM chip is a physical piece of hardware.

Not anymore. It's integrated right into the CPU nowadays; and especially since we're talking about "gaming" motherboards, we're also talking about "gaming" CPUs (i.e., not bargain basement stuff), and every gaming CPU sold in at least the past 5-8 years has it.

And if that's too vague for you, then there's a simpler statement: every CPU officially supported by Windows 11 has the requisite TPM built in. (Most BIOSes shipped until very very recently disabled it by default though, so if a hardware compatibility tool tells you that you don't have a TPM despite having a supported CPU, you just need to boot into the BIOS and enable it.)
