These numbers come from the video tests linked below.
| Test | RTX 5090 Lightning Z | RTX 5090 | RTX PRO 6000 |
|---|---|---|---|
| Wan 2.2 5B in ComfyUI | 109 sec | 113 sec | 120 sec |
The RTX 5090 was fastest in this test. The RTX PRO 6000 was slower, but its 96 GB memory can hold a much bigger model.

| Lacksan price | $3,269–$4,399 |
| Video use | Small NVIDIA computer for local video |
| Most it can hold | Up to RTX 4000 SFF Ada · 20 GB of GPU memory |
| What to pick | Choose 16–20 GB for Q4 test videos. Pick a tower with 24 GB or more for better videos of people. |
| YouTube lesson | Q4 shrinks Wan to 9 GB, but the person test showed softer faces and identity drift. |
