Unverified50% confidenceDecision RuleExact time
The expert FFN weights of MoE models occupy most of the volume, but only a small portion is read each time, so this part should be placed in RAM, and when RAM is insufficient the operating system pages it in from the SSD.

UnverifiedAlthough MoE models have low computational requirements, the entire model still needs to be loaded into memory, so the total memory requirement is not low; however, memory bandwidth pressure is greatly reduced because only the activated parameters are read each time.73% similarUnverifiedWhen streaming experts from an SSD, if the expert weight blocks are large (a single expert may be several hundred MB), the read granularity can approach sequential, and the performance loss is relatively controllable.68% similarUnverifiedThe file size and VRAM usage of a MoE model depend on the total parameter count rather than the activated parameter count, because all expert weights need to be stored.67% similarUnverifiedInferencing a 1T-parameter MoE model requires hundreds of gigabytes of VRAM even with BF16 half-precision storage, far exceeding the capacity limit of consumer-grade GPUs.66% similarUnverifiedWhen a model runs, its weights need to be loaded into RAM (system memory) or VRAM (video memory), and having large storage capacity does not mean the model can actually run.65% similar
