AMD CPUs should be cheaper to manufacture, because their chips are much smaller. Xeons are built using giant monolithic dies, so the defect rate per wafer matters a lot. EPYC processors from AMD are built using 9 separate chips under one package [1]: one I/O die and several chiplets with multiple cores each, so the yields should be much higher.
