How it’s rated

Quality 16Basic quality (D) · 16 of 100: how capable the model is at F16, whatever it runs on. Match score 50/100 (quality, fit, speed and memory use) sets the ranking.
How capable the model itself is at F16, 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 great
How well it runs on the NVIDIA RTX A6000: 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.

Quick answers

How much memory does Spark X2.6 1.7B need on the NVIDIA RTX A6000 48GB?

At F16 it needs about 6.5 GB. The NVIDIA RTX A6000 48GB has 48.0 GB usable.

How fast is Spark X2.6 1.7B on the NVIDIA RTX A6000 48GB?

About 129 tok/s at F16, an estimate from the hardware’s memory bandwidth and the size of the model.

Which quantization of Spark X2.6 1.7B should I use on the NVIDIA RTX A6000 48GB?

F16. 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.
