Not sure, but note that with the 2020 for performance it's best to use RAM of the same capacity, speed and manufacturer to get the best performance so if looking to upgrade with 3rd party RAM it shouldn't matter which of these configs you get as you probably won't be able to use the existing RAM anyway.If I was to get an iMac 27” from apple site with 16gb, do they ship with 4x4gb or 2x8gb?
it’s a refurb
