This is a misconception. These crypto keys are only designed to protect RSA and ECC private key, and encrypt symmetric key instead of actual data, for good reasons. The actual symmetric encryption is still performed on the host computer, the actual AES key can still be stolen from a CPU side-channel.
Are these tokens any good? Yes, they guard your private key. Is it enough to protect you from Spectre? No.
