Can the NVIDIA RTX A500 Laptop GPU run Gemma 4 12B?

82Great quality (A) · 82 of 100: how capable the model is at Q6_K, whatever it runs on. Match score 61/100 (quality, fit, speed and memory use) sets the ranking.

Yes, but slowly (heavy RAM offload)

Slow (heavy RAM offload). At Q6_K it needs about 11.3 GB of 4.0 GB usable, with an estimated speed of 5.3 tok/s.

How it’s rated

Quality 82Great quality (A) · 82 of 100: how capable the model is at Q6_K, whatever it runs on. Match score 61/100 (quality, fit, speed and memory use) sets the ranking.
How capable the model itself is at Q6_K, 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 Slowheavy RAM offload
How well it runs on the NVIDIA RTX A500 Laptop GPU: 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.

Other hardware that runs it

Quick answers

How much memory does Gemma 4 12B need on the NVIDIA RTX A500 Laptop GPU 4GB?

At Q6_K it needs about 11.3 GB. The NVIDIA RTX A500 Laptop GPU 4GB has 4.0 GB usable.

How fast is Gemma 4 12B on the NVIDIA RTX A500 Laptop GPU 4GB?

About 5.3 tok/s at Q6_K, an estimate from the hardware’s memory bandwidth and the size of the model.

Which quantization of Gemma 4 12B should I use on the NVIDIA RTX A500 Laptop GPU 4GB?

Q6_K. 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.
