Processing in Memory: DRAM Is About to Do Math
Samsung's LPDDR5X-PIM puts compute inside commodity memory, exposing 614 GB/s of bank-level bandwidth for local LLM inference. The silicon works. Quantization, memory layout, and runtime support now stand in the way.
Summary
Samsung’s new LPDDR5X-PIM technology integrates computing capabilities directly into memory, enabling high bandwidth for local large language model inference. However, challenges like quantization and memory layout need to be addressed for optimal performance.
