AMD is now projected to follow the EPYC Milan series of high-performance CPUs with their Zen 4-based Genoa successors. This silicon is already purported to boost its RAM support to the tune of 12 channels (as opposed to 8 in Milan) - and in DDR5, too. Now, a new leak builds on these claims with hints at a maximum capacity of no less than 12TB.
This new rumor has been sparked by a diagram allegedly showing the layout of a new "Titanite 2P2G" rig in which dual EPYC Genoas do indeed seem to be connected to 12 separate modules of RAM (each of which are...yep, DDR5) each.
According to a further tip from ComputerBase, each of them could be 1TB in size - however, this only applies if each one is 3DS RDIMM in nature. This form of memory has an extremely advanced 16-rank structure - however, it apparently comes with the compromise of reducing the maximum transfer rate to 4,000MT/s, as opposed to a theoretical 5,200MT/s using 4- or 8-ranks LRDIMM with 256GB per channel instead.
Nevertheless, the rumored leap to 12-channel support remains a pretty intriguing prospect; plus, as TechPowerUp points out, the bandwidth implied with the alleged new spec might make up for the drop in apparent max speed.
