CPU offloading refers to moving some model layers from VRAM to system memory, with the CPU handling the computation, thereby breaking through VRAM capacity limits.

VerifiedThe CPU offloading strategy keeps the weights of inactive experts resident in system memory and only temporarily loads them into GPU VRAM when selected by the router, at the cost of introducing PCIe bus transfer latency.78% similarUnverifiedWeight offloading refers to moving some of the model's layers or experts from VRAM to slower storage tiers such as memory or NVMe drives, swapping them in on demand at runtime, which sacrifices inference speed.77% similarUnverifiedOn PC platforms, when VRAM is insufficient, part of the model can be offloaded to system memory, reducing speed but still allowing it to run; on Mac, when unified memory is insufficient, the model immediately reports an error and exits.75% similarUnverifiedCPU cache is a high-speed memory inside the processor, used to reduce the latency of accessing main memory.74% similarUnverifiedWhen running a 1B-parameter model purely on CPU, the bottleneck is mainly memory bandwidth rather than compute: every generated token requires reading the model weights from memory once, so quantization level, CPU core count and memory frequency greatly affect speed.74% similar
