I haven’t seen any reviews taking into account the price of unregistered DDR4 RAM at the densities required to use these things. AMD is suggesting 2GB/core or 128GB, but these HEDT CPUs cannot support the typical registered RAM used by server memory kits and require unregistered desktop RAM (for market segmentation, you see) which can be (depending on SKU) quite a bit more expensive. I feel any price comparisons with Epyc or Xeon need to take that into account.
