Meta reuses old server memory with custom CXL ASIC, cuts inference machines 25%
Meta developed a custom CXL ASIC to repurpose memory from decommissioned servers, now in production on millions of boxes. The chip enables pooling and sharing of memory across hosts, reducing the number of machines needed for some inference workloads by 25%. This approach lowers costs and extends hardware lifespan, addressing data center efficiency challenges.
Meridian48 take
A clever hardware reuse play that saves Meta money, but the 25% reduction is specific to certain inference workloads, not a blanket efficiency gain.
