Stable Diffusion 3.5 Large Turbo on Intel Core i5-1240P / i5-1340P NAS (16 GB)

Can the Intel Core i5-1240P / i5-1340P NAS (16 GB) run Stable Diffusion 3.5 Large Turbo?

Barely: it runs very slowly (encoder unloaded after use)

Very slow (encoder unloaded after use). At Q4 GGUF it needs about 7.5 GB of 12.0 GB usable and takes about 3.0 min per image.

Best precision: Q4 GGUF
Memory mode: Text encoder offloaded
Time per image: 3.0 min
Output: 1024×1024, 4 steps

How it’s rated

Quality 57Good quality (B) · 57 of 100: how capable the model is at Q4 GGUF, whatever it runs on. Match score 63/100 (quality, fit, speed and memory use) sets the ranking.: How capable the model itself is at Q4 GGUF, 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 Very slowencoder unloaded after use: How well it runs on the Intel Core i5-1240P / i5-1340P NAS (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.	25.9 / 45
Memory fitFull marks when the model fits in the share of the NAS’s memory that models can use (the rest stays with the NAS system and its storage services); fewer when it goes past that limit.	20.0 / 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.	14.3 / 15
Match score	63.8 / 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 Stable Diffusion 3.5 Large Turbo need on the Intel Core i5-1240P / i5-1340P NAS 16GB?

At Q4 GGUF it needs about 7.5 GB. The Intel Core i5-1240P / i5-1340P NAS 16GB has 12.0 GB usable.

How long does Stable Diffusion 3.5 Large Turbo take on the Intel Core i5-1240P / i5-1340P NAS 16GB?

About 3.0 min per image at Q4 GGUF 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.
