The second generation AMD EPYC, called Rome, with "enhanced" performance and security, was launched in 2019.
Support for AMD EPYC Rome has been merged with the Linux kernel since the 5.4 series. Therefore, all versions of Ubuntu with the 5.4 kernel installed support this processor and all its new features.
