Can the GeForce RTX 4070 Super run DeepSeek R1 (671B)?

Does not fit at Q4_K_M.

DeepSeek R1 (671B) is 671B parameters (MoE; all experts resident). At Q4_K_M the weights are about 375.0 GiB; with the 1.5 GiB runtime reserve that is 376.5 GiB against the card's 12GB, about 364.5 GiB more than the card has.

Verdict rules: fits comfortably when weights plus reserve sit within 85% of VRAM; tight when they fit with little left for context; CPU offload when they exceed VRAM by up to 2x (runs, slowly, with layers in system RAM); no beyond that. The KV cache per token depends on the model's architecture and is not modelled here.

Not this card. These fit it comfortably at Q4.

Nothing in the consumer catalog fits DeepSeek R1 (671B) at Q4 on a single card; this is multi-GPU or datacenter territory, or a job for hosted inference (see PicksByModel for per-token pricing).
