AMD is spotlighting MEXT, a software solution designed to mitigate DRAM supply constraints and expenses across its EPYC server processors. The technology enables NVMe flash storage to function as an extension of system DRAM, aiming to maintain comparable performance levels even with a 50% cut in DDR5 capacity. [1][2]
The software relies on artificial-intelligence-based page prediction to manage memory workloads efficiently. [1]
The push comes as memory industry supply imbalances persist. According to Wccftech, DRAM costs by themselves currently account for 75% of the total price of a server, driving demand for architectures that rely less heavily on scarce memory modules. [2]
AMD has brought more attention to MEXT, software that uses AI-based page prediction to make NVMe flash act as an extension to server DRAM. The idea is to keep frequently used data in DRAM while moving colder memory pages to flash, then predict which pages an application will need and return them to DRAM before they...

AMD MEXT is a brand new memory solution that utilizes Flash to mitigate DRAM costs and supply concerns across EPYC CPUs. AMD MEXT Aims To Address The Ongoing DRAM Crisis Through An Innovative "Flash-Based" Memory Solution The memory supercycle continues to rage, and supply/demand continues to worsen. Today, the DRAM cost alone makes up 75% of the total server cost, and DRAM manufacturers face shortages that show no sign of ending.
