Why Chinese CPUs Require Full Memory Population: Chiplet NUMA vs Intel's Monolithic Design

Domestic Chinese server CPUs using chiplet architectures create many fine-grained NUMA nodes per socket, each needing local memory; unlike Intel's monolithic single-NUMA-node design with mature interconnects and kernel optimizations, partial memory population forces remote access over slower chiplet interconnects, causing severe performance drops.
