In theory, any C0 die (based on alder lake 8+8) CPU should be unaffected by the microcode bug (since they use different microcode to raptor lake) or the manufacturing fault, because they use a different process to manufacture them.very early models of 13th were rebadged 12th gen's at heart, those 13th gen units may be un affected but given current events dont 100% bank on them being fine long term.
