VRAM 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.

UnverifiedWhen 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% similarUnverifiedCPU-GPU hybrid inference (offloading) introduces a significant drop in inference speed.77% similarUnverifiedNon-deterministic GPU operations are designed to prioritize performance over determinism; forcing a fixed execution order introduces numerous synchronization barriers that significantly reduce parallel efficiency.75% similarUnverifiedGPU的SIMD架构在推理阶段面临结构性错配，推理时batch size较小导致算力利用率不足，内存带宽成为核心瓶颈73% similarUnverifiedGPU-CPU synchronization has unpredictable blocking times under high concurrency, potentially introducing hundreds of microseconds or even millisecond-level additional wait times on certain requests.73% similar
