AMD has launched MEXT, a memory solution for EPYC CPUs that utilizes Flash storage to mitigate rising DRAM costs and supply constraints. With DRAM now exceeding $10 per GB and accounting for 75% of server costs, MEXT offloads cold memory pages to Flash drives.
The software uses the Double-Click AI Engine to address the 500x latency gap between Flash and DRAM. Running on a single EPYC core, this AI trains in under a second to optimize performance. MEXT can reduce DRAM usage by up to 75% while tripling memory capacity.
MEXT Phase 1 is now available for EPYC systems with NVMe. Testing shows a 3.4x performance-per-dollar increase in Agentic AI tasks. AMD projects an 83% cost saving over all-DRAM setups, potentially avoiding $4.9 million in costs for initial server deployments.
