What requires RAM offload?

Offload is shown only when the model does not fully fit in usable VRAM but stays within the modeled offload allowance.

Performance

Separate from memory fit. Runtime is llama.cpp · quantization bucket Q4 (GGUF Q4_0 maps to Q4). Workload is llama-bench pp512 / tg128 (short context, batch 1, full GPU offload). This is not a ranking and not a 8K–128K speed claim.

Model: Llama 3.2 1B Instruct
GPU: NVIDIA RTX 3080 10 GB
Runtime: llama.cpp · CUDA · model 1.0.0
Decode: ~685 tok/s · Calibrated estimate · MEDIUM confidence (spread ~603 tok/s–~767 tok/s)
Prefill: ~30273 tok/s at a 512-token prompt · Calibrated estimate · MEDIUM confidence
Time to first token: ~17 ms for a 512-token prompt (512 / prefill tok/s). Not estimated at 8K–128K.
