GPUs/Intel Arc A750/LTX Video

Can Intel Arc A750 run LTX Video?

2B parameter Video Gen model on 8GB GDDR6

Yes — runs at 8-bit quantization
~0.2-0.3 clips/min
SpeedFast inference, near-native speed
QualityNear-lossless — virtually identical to FP16
LTX Video works best with NVIDIA CUDA. Your Intel 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 Intel Arc A750 has 8GB, so you'll need to quantize it to 8-bit (Q8) to fit.

FP16 (Full Precision)10GB (need 2GB more)

Maximum quality, no quantization

Q8 (8-bit)6GB (2GB free)

Near-lossless, ~50% size reduction

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

Good quality, ~75% size reduction

Your GPU VRAM: 8GB GDDR6 at 512 GB/s bandwidth
Recommended system RAM: 32GB DDR5 (2x GPU VRAM minimum for model overflow)

What This Means in Practice

LTX Video at 8-bit precision on Intel Arc A750 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.
