AMD发布面向EPYC的MEXT闪存内存方案
AMD公布面向EPYC服务器的MEXT软件驱动内存方案。该方案利用AI将冷内存页从DRAM迁移至闪存,同时把预计即将使用的页面保留在DRAM中。系统包括Linux驱动、AI引擎和RAM View可观测平台。AMD称,该方案可将DRAM使用量减少20%至75%,同时维持相近性能。Phase 1可部署于配有专用NVMe硬盘或盘位插槽的EPYC服务器;Phase 2计划提供授权,并预装RAM View。
AMD将MEXT定位为一种软件化方案,用于在DRAM供应压力下降低数据中心成本并扩展内存容量。原报告列出的潜在工作负载包括智能体AI、EDA与芯片设计、数据库与分析,以及媒体与娱乐。
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.

Although DRAM prices have seen a major reduction over time if we compare the ~$50M / GB cost from the 1970s to ~$8 / GB in the 2010s (a 6,000,000x reduction driven by Moore's Law), recently, the prices have surged beyond ~10 / GB and continue to rise.
