Can NVIDIA Tesla P40 run Wan Video 14B?

14B parameter Video Gen model on 24GB GDDR5X

Yes — runs at 8-bit quantization

~0.1-0.2 clips/min

SpeedFast inference, near-native speed

QualityNear-lossless — virtually identical to FP16

VRAM Requirements

Wan Video 14B is a 14B parameter model. At full precision (FP16), it requires 32GB of VRAM. Your NVIDIA Tesla P40 has 24GB, so you'll need to quantize it to 8-bit (Q8) to fit.

FP16 (Full Precision)32GB (need 8GB more)

Maximum quality, no quantization

Q8 (8-bit)18GB (6GB free)

Near-lossless, ~50% size reduction

Q4 (4-bit)11GB (13GB free)

Good quality, ~75% size reduction

Your GPU VRAM: 24GB GDDR5X at 346 GB/s bandwidth
Recommended system RAM: 48GB DDR5 (2x GPU VRAM minimum for model overflow)

What This Means in Practice

Wan Video 14B at 8-bit precision on NVIDIA Tesla P40 generates video clips with near-identical quality to full precision. Generation times are similar — video gen is bottlenecked by compute more than memory at this precision. A solid setup for local video generation.
