Can AMD Radeon RX 7600 run LTX Video?
2B parameter Video Gen model on 8GB GDDR6
VRAM Requirements
LTX Video is a 2B parameter model. At full precision (FP16), it requires 10GB of VRAM. Your AMD Radeon RX 7600 has 8GB, so you'll need to quantize it to 8-bit (Q8) to fit.
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
LTX Video at 8-bit precision on AMD Radeon RX 7600 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.
