How CXL Unlocks the Memory Capacity KV Cache Needs
Currently, the AI industry's primary constraint is shifting from compute to memory as the demand for KV Cache skyrockets. By 2026, severe bottlenecks are expected due to limited supply versus increasing needs for larger context windows and batch sizes. CXL technology is highlighted for its role in creating a new memory tier that alleviates these issues, alongside the exploration of KV Cache offloading and footprint compression to tackle memory efficiency.
