GPUs are scored on four axes: capability (45%), speed (30%), value (20%) and efficiency (5%), each normalised across the whole ranking.
Capability means the intrinsic strength of the best model the card can hold — not how many models fit, and not how fast it streams a small one.
Speed is capped at 40 tok/s: past that, more throughput does not change how the model feels to use.
Apple Silicon is excluded from this ranking. Those entries price a whole computer and rate a chip's package power, so on price-per-capability and performance-per-watt they would beat every add-in card by construction. Apple hardware is covered on the macOS platform page instead.
Licence importance is set to the maximum (1.0) — this is the one workload where a non-commercial or restricted licence is disqualifying in practice regardless of capability, so it is weighted as heavily as the model's own quality.

The NVIDIA GeForce RTX 5090 — 32 GB of VRAM runs 77 qualifying models, the strongest being Gemma 4.

The Intel Arc B570 at $219, which runs 53 qualifying models.

8 GB is the entry point at which a model for this workload will run at all. More memory buys a stronger model, not just a faster one.
