# Memory Scarcity Drives Server Memory Tiering

As AI accelerators absorb memory supply, chip vendors and operators increasingly replace DRAM capacity with predicted tiering to flash and CXL memory, turning memory placement software into a competitive product.

- [confirms] AMD says its Mext software keeps up to 99% of server performance with half the DRAM by moving cold pages to NVMe (2026-11-13): AMD says its licensed Mext software keeps up to 99% of server performance with half the DRAM by moving cold pages to NVMe, though that figure comes from one Spark workload on Azure (a chip-design test kept 80% of performance with 75% of memory on flash). A major chip vendor selling closed-source tiering software turns memory placement into a paid product.
