How it’s rated

Quality 58Good quality (B) · 58 of 100: how capable the model is at F16, whatever it runs on. Match score 76/100 (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 AMD Radeon RX 7900 XTX: 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 Fara 1.5 4B need on the RX 7900 XTX 24GB?

At F16 it needs about 11.1 GB. The RX 7900 XTX 24GB has 24.0 GB usable.

How fast is Fara 1.5 4B on the RX 7900 XTX 24GB?

About 52.4 tok/s at F16, an estimate from the hardware’s memory bandwidth and the size of the model.

Which quantization of Fara 1.5 4B should I use on the RX 7900 XTX 24GB?

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.
