IDK. I have a spare computer, with a Zen3 in it, and no stutter to be seen.
Presumably this is with the Secure Boot enabled ? I have another Zen3,
which is the machine reserved for Secure Boot testing, it has no TPM
and uses the AMD fTPM, and no stutter there either. It has booted Linux
Secure Boots and Windows Secure Boots, as part of testing a while ago.

Both machines, the BIOS version is the most recent. Both got flashed up.

The difference with laptops, is the BIOS support may not be as generous.
