AMD’s current Zen 3 based EPYC CPUs are already a force to be reckoned with. Recent reports suggest that AMD wants to take this even further with its upcoming Zen 4 based EPYC CPUs, which are expected to support up to 12TB of DDR5 RAM.

According to the latest Linux Error Detection and Correction driver patch for EPYC processors (found by Phoronix) indicates that this new patch adds support for Registered DDR5 (RDDR) and Load-Reduced DDR5 (LRDDR) memory. Meanwhile, AMD’s current EPYC CPUs only support DDR4 RAM.

Apart from that, the new patch also confirms that AMD’s upcoming 7004 Series of EPYC CPUs will support up to 12 memory controllers per CPU socket, up from eight controllers found on AMD’s current server-grade CPUs.

Theoretically, this update could take the available memory bandwidth from 204.8GB/s to a whopping 460.8GB/s per socket, which equals about a 150x increase in bandwidth over its current generation EPYC CPUs that come with 3200Mhz DDR4 memory. 

And we can still expect that the improvements on AMD’s next-generation EPYC’ Genoa’ CPUs won’t stop over here, as 12 memory channels will also allow for memory capacities as high as 1TB per channel. Something which could be possible in the near future, as we have seen with Samsung’s claim, which suggests that RAM modules as large as 768GB are already possible.

Overall, it looks like AMD’s Zen 4 EPYC processors will provide a tangible improvement in terms of memory compared to AMD’s existing server processors. We can’t wait to see how these new CPUs will fare out against Intel’s next-gen Xeon lineup of server-grade CPUs once both of them are made available sometime in 2022.
