How it’s rated

Quality 93Excellent quality (A+) · 93 of 100: how capable the model is at Q5_K_M, whatever it runs on. Match score 90/100 (quality, fit, speed and memory use) sets the ranking.
How capable the model itself is at Q5_K_M, 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 well
How well it runs on the Intel Core Ultra 5 225 / 7 265 / 9 285 (desktop) NAS (192 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.42.1 / 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.25.0 / 25

How much memory does Qwen3.8 Flash Next (125B-A6B) need on the Intel Core Ultra 5 225 / 7 265 / 9 285 (desktop) NAS 192GB?

At Q5_K_M it needs about 142 GB. The Intel Core Ultra 5 225 / 7 265 / 9 285 (desktop) NAS 192GB has 173 GB usable.

How fast is Qwen3.8 Flash Next (125B-A6B) on the Intel Core Ultra 5 225 / 7 265 / 9 285 (desktop) NAS 192GB?

About 12.1 tok/s at Q5_K_M, an estimate from the hardware’s memory bandwidth and the size of the model.

Which quantization of Qwen3.8 Flash Next (125B-A6B) should I use on the Intel Core Ultra 5 225 / 7 265 / 9 285 (desktop) NAS 192GB?

Q5_K_M. Of the versions that fit, it is the one that runs best; when two run equally well, the check prefers the higher-rated one.

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.
