UnverifiedThe access latency of unified memory is not uniform: data is fast when located in VRAM, but when located in host memory it must be transferred via PCIe/NVLink, causing performance fluctuations.76% similarVerifiedThe 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).76% similarUnverifiedMemory bandwidth is a metric measuring the rate of data transfer between the processor and memory, usually expressed in GB/s.74% similarUnverified主机卸载用带宽换显存空间，代价是数据传输延迟；激活重计算用算力换显存，二者可互补配合73% similarUnverifiedMemory capacity determines whether the parameter count plus the KV Cache can fit into the device; memory bandwidth determines the speed of weight reads during each token generation in the decoding phase, and thus directly determines inference latency.71% similar
