UnverifiedThe cost of HNSW is relatively high memory usage, typically requiring 1.5 to 2 times the raw vector data size in additional space to store the graph structure.71% similarUnverifiedMainstream ANN algorithms include the graph-based HNSW and the quantization-based IVF-PQ; HNSW trades higher memory usage for better recall, while IVF-PQ reduces storage costs through compression.71% similarUnverified模型规模越大,记忆能力反而越强,因为更大的模型拥有更强的参数容量来存储低频样本68% similarUnverifiedWhen running local LLMs, VRAM capacity is often more critical than computational speed, as VRAM capacity directly determines which models can be run.67% similarUnverifiedCompared to conventional GDDR6 memory, HBM can deliver 3–5 times higher memory bandwidth while consuming less power and occupying a smaller package footprint.67% similar
