Can AMD Radeon RX 7700 XT run LTX Video?
2B parameter Video Gen model on 12GB GDDR6
VRAM Requirements
LTX Video is a 2B parameter model. At full precision (FP16), it requires 10GB of VRAM. Your AMD Radeon RX 7700 XT has 12GB — enough to run it without any quantization.
Maximum quality, no quantization
Near-lossless, ~50% size reduction
Good quality, ~75% size reduction
Recommended system RAM: 32GB DDR5 (2x GPU VRAM minimum for model overflow)
What This Means in Practice
AMD Radeon RX 7700 XT 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.
