Normally, certification of a memory module by Intel would be mundane, but this module is special; it combines capacity, low power consumption, and performance, thus potentially saving data center operators millions of dollars.

AI servers not only consume plenty of premium high-bandwidth memory (HBM) used on AI accelerators like Nvidia B300, but also tons of commodity server DDR5 SDRAM that connect to x86 processors. A single high-capacity DDR5 memory module can consume up to 15W or even 25W (depending on performance, capabilities, and workloads), so a fully equipped 12-channel Xeon 6 memory subsystem can draw between 180W and 300W, comparable to the CPU's power consumption.

A 32 Gb memory chip made on SK hynix's 1b process technology (5 th Generation 10nm-class DRAM process) consumes significantly less power than two 16 Gb memory ICs made on the company's 1a production node (4 th Generation 10nm-class DRAM node), so using a 256 GB DDR5 RDIMM based on the latest DRAMs leads to significant energy savings.
