Supercharging Agentic AI: How Leo X-Series Smart Memory Controllers Accelerate Inference With KV Cache Offload

In the early days of chat-based LLMs, the memory wall was driven by linear context growth. For each individual inference workload, expanding context length pushed available memory demand beyond capacity. But we are now in the agentic era. Agentic workloads operate on dynamic loops: They generate reasoning tokens, call external tools and APIs, parse returned data, and append state updates across dozens or hundreds of execution turns. Operating in parallel, the CPU tokenizes requests, performs RAG lookups, manages session state, and prepares prefill metadata while the GPUs serve the system’s many users. This continuous execution cycle fundamentally reshapes how the KV cache strains GPU and CPU memory. As AI inference moves from isolated workloads to always-on agentic systems, the memory path — not just compute — determines how quickly users see a response. Can help orchestrate a massive amount of simultaneous agentic inference? Minimizes latency and reduces time to first token (TTFT)? Maximizes throughput to increase tokens per second? Efficiently uses CPU cores and attached memory? The answer is an innovative architectural solution: a fabric-attached memory tier…
