Can AMD Radeon RX 7900 GRE run LTX Video?

2B parameter Video Gen model on 16GB GDDR6

Yes — runs at full precision
~0.2-0.3 clips/min
SpeedFastest possible inference
QualityMaximum quality, no degradation
LTX Video works best with NVIDIA CUDA. Your AMD GPU may have limited or no support.

VRAM Requirements

LTX Video is a 2B parameter model. At full precision (FP16), it requires 10GB of VRAM. Your AMD Radeon RX 7900 GRE has 16GB — enough to run it without any quantization.

Recommended system RAM: 32GB DDR5 (2x GPU VRAM minimum for model overflow)

What This Means in Practice

AMD Radeon RX 7900 GRE can run LTX Video at full precision for video generation. You can generate short video clips from text prompts or images at maximum quality. Video generation is very compute-intensive — expect each clip to take 30 seconds to several minutes depending on resolution and length.
