What GPU Do You Need for Wan 2.1 1.3B?, frames/s by GPU
Efficiency: frames/s per 100W drawn
Power is the average pulled during the run, sampled at 1Hz. The fastest card is often not the one here, and for anything left running this is the number that shows up on the bill.
Value: frames/s per $1,000 of MSRP
Launch price, not street price, so it ages. A speed leaderboard always crowns the most expensive card; this is the counterweight.

How we test
Wan 2.1 1.3B in diffusers, bf16, one warmup clip and three timed clips from the same prompt, measured as frames of finished video per second, with CPU offload only on cards below the model's full-GPU size. Text-to-video is compute-bound and memory-hungry; cards that need CPU offload lose far more speed than their raw compute suggests.
