Can the NVIDIA Jetson Orin NX 16GB (16 GB) run FLUX.2 [klein] 9B?

82Great quality (A) · 82 of 100: how capable the model is at FP8, whatever it runs on. Match score 81/100 (quality, fit, speed and memory use) sets the ranking.

Yes, it runs well (tight fit · encoder unloaded after use)

Runs well (tight fit · encoder unloaded after use). At FP8 it needs about 11.7 GB of 13.6 GB usable and takes about 17 s per image.

How it’s rated

Quality 82Great quality (A) · 82 of 100: how capable the model is at FP8, whatever it runs on. Match score 81/100 (quality, fit, speed and memory use) sets the ranking.
How capable the model itself is at FP8, from its editorial quality tier scaled by the quantization or precision. It’s the same on any hardware that runs this variant. Scale: A+ 85+ · A 70+ · B 55+ · C 40+ · D under 40.
Runs Runs welltight fit · encoder unloaded after use
How well it runs on the NVIDIA Jetson Orin NX 16GB (16 GB): speed, capped by how well it fits in memory. Runs great: 30+ tokens/s (or near the image, video or decision speed target) · Runs well: 10+ tokens/s · Slow: 3+ tokens/s · Very slow: under 3 · Won’t run: doesn’t fit even with offload. A tight fit or RAM offload caps it at Runs well; heavy offload caps it at Slow.

Match score

To order lists, each result also gets a match score out of 100 from four parts. It favors the most capable model that still runs well.

Model qualityEditorial quality tier of the model, scaled by the quantization or precision used.37.0 / 45
Memory fitFull marks when the model fits in the share of unified memory the GPU can use; fewer when it goes past that limit.18.0 / 25
SpeedGeneration speed against a 40 tokens/s target for LLMs, or render time against a target for image and video.11.5 / 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
Match score81.5 / 100

The match score orders results; it is not shown as a grade. Quality and Runs are the two ratings in the tables.

Quick answers

How much memory does FLUX.2 [klein] 9B need on the NVIDIA Jetson Orin NX 16GB 16GB?

At FP8 it needs about 11.7 GB. The NVIDIA Jetson Orin NX 16GB 16GB has 13.6 GB usable.

How long does FLUX.2 [klein] 9B take on the NVIDIA Jetson Orin NX 16GB 16GB?

About 17 s per image at FP8 and default settings, an estimate scaled from a reference timing by this hardware’s compute speed.

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.
