UnverifiedGPU HBM has the lowest access latency but limited capacity and the highest cost; CPU DRAM has larger capacity but access requires passing through the PCIe bus with significantly increased latency; the bandwidth gap between different tiers often reaches more than an order of magnitude.71% similarUnverified冯·诺依曼瓶颈指处理器和存储之间的数据传输带宽限制71% similarUnverifiedIn video generation scenarios, increasing frame count causes sequence length to grow rapidly, with KV cache volume growing linearly, making it easy to exceed on-chip SRAM capacity and degrade to lower-bandwidth HBM, creating a real-time bottleneck.70% similarUnverifiedThe traditional one-site-one-process model has two problems in high-density hosting scenarios: linearly growing memory overhead and high CPU context-switching costs.69% similarVerifiedThe bottleneck in running large models locally lies in VRAM capacity and bandwidth; the CPU is not the critical factor69% similar
