VerifiedThe access latency of object storage is typically in the range of tens to hundreds of milliseconds, far higher than local SSD (microsecond-level) or memory (nanosecond-level).75% similarUnverifiedGPU 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% similarUnverifiedGPU global memory access latency can reach hundreds of clock cycles, while on-chip shared memory latency is only tens of cycles.70% similarUnverified纯内存操作的延迟通常比向量数据库方案低1-2个数量级，Redis等内存数据库的P99延迟可控制在1ms以内，而远程向量检索往往需要10-100ms70% similar
