What does it matter if it's CRC or sha512 if they are using an unsecured connection to transmit them? A stranger who has already acquired capability to modify the payload in transit can also modify the checksum. A better hash will not solve this problem.
They use https now, but use CRC for signature verification:
AMD told MrBruh that all update communications now use HTTPS and that updates undergo signature verification. The researcher says he verified the HTTPS claim, but found only a CRC32 check on the downloaded executable, which is not considered a cryptographic signature.
I could be wrong here, but I believe they should use a combination of SHA256 and PGP for signature verification.
