UnverifiedFor modern CPUs and GPUs, memory bandwidth is often the true bottleneck for inference speed rather than the compute units' arithmetic throughput, which is why quantization can bring speed improvements.80% similarUnverified研究《Accelerating Block Low-Rank Foundation Model Inference on Memory-Constrained GPUs》提出基于块低秩分解的方案压缩内存并加速推理79% similarUnverifiedCPU Offload推理与纯显卡推理相比速度差距通常在5-10倍量级78% similar
