UnverifiedTraditional GPU memory relies primarily on HBM, which achieves high bandwidth through 3D stacking and ultra-wide buses but has limited capacity, high expense, and significant power consumption75% similarUnverifiedKeeping model weights fully resident in GPU memory avoids memory swap-in/swap-out overhead, whereas models that exceed GPU memory capacity require data to be moved between CPU and GPU, causing latency to rise significantly.72% similarUnverifiedIn production environments, the average GPU utilization is often low, due to reasons including data loading bottlenecks, communication overhead, and improper batch size settings.72% similarUnverifiedIn the GPU memory hierarchy, SRAM is fast but has extremely limited capacity, while HBM has large capacity but relatively limited bandwidth.72% similarUnverifiedThe core bottleneck in large model inference on GPUs is memory bandwidth; autoregressive generation of each token requires loading the full KV Cache from HBM, with compute utilization typically below 5%.71% similar
