VerifiedWhen model parameter size exceeds GPU VRAM capacity and needs to be offloaded to system memory, inference speed drops sharply from tens of tokens per second to single digits.79% similarUnverifiedCompared to GPU inference, CPU inference is often orders of magnitude slower78% similarUnverifiedIn scenarios of pure GPU inference, especially low concurrency, the impact of the CPU on performance is quite limited77% similarUnverifiedVRAM offloading refers to transferring weights or activations that are temporarily not involved in computation from GPU VRAM to system memory or disk during inference, at the cost of latency incurred when moving them back to the GPU, which results in reduced inference speed.77% similarVerified推测解码、模型蒸馏、KV Cache优化等推理优化技术的持续进步正在使单位推理成本快速下降76% similar
