UnverifiedIn single-batch scenarios where batch size is 1, the arithmetic intensity of matrix multiplication drops significantly, memory bandwidth becomes the primary bottleneck, and the efficiency of traditional GPU architectures optimized for high throughput decreases markedly.80% similarUnverifiedPursuing extremely low latency means decreased GPU utilization and rising per-inference costs.79% similarVerifiedThe bottleneck in large model inference is often not compute but memory bandwidth, and GPU compute utilization during the inference phase is often less than 10% of peak.79% similarVerifiedIn high cache-hit-rate scenarios, blindly adding GPUs may yield little benefit; the bandwidth bottleneck should be identified before optimization.78% similar
