Can the Intel Core Ultra 200H (Arc 140T) (96 GB) run LTX-2 (19B, video + audio)?

79 ptsGreat (A) · 79 of 100 points: Model quality 36.2/45, Memory fit 25.0/25, Speed 3.5/15, Memory use 15.0/15

Yes, it runs well

Runs well. At FP8 it needs about 44.3 GB of 54.7 GB usable, with an estimated speed of 56.0 min.

How the A grade is scored

Every result gets up to 100 points from four parts. The points decide the letter grade.

Model qualityEditorial quality tier of the model, scaled by the quantization or precision used.36.2 / 45
Memory fitFull marks when everything sits in GPU or unified memory; fewer when part spills to system RAM.25.0 / 25
SpeedGeneration speed against a 40 tokens/s target for LLMs, or render time against a target for image and video.3.5 / 15
Memory useRewards using the memory you have, so a bigger, better variant beats a tiny one that leaves most memory idle.15.0 / 15

Other hardware that runs it

Estimates come from published hardware specs and our open formulas, not from running the model on your machine. Real speed varies with runtime, drivers and settings. Numbers marked “Measured” come from a linked benchmark.
