How these numbers are calculated
- 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.
- Ranked as a *base model* choice, not an assistant choice: licence weight is near-maximum (0.9) because a restrictive licence blocks distributing what you train, and latency is nearly ignored (0.2) because training throughput, not decode speed, sets the cost.
FAQ
What is the best GPU for fine-tuning a base model?
The Intel Arc Pro B70 — 32 GB of VRAM runs 151 qualifying models, the strongest being Qwen 3.7.
What is the cheapest GPU that works for fine-tuning a base model?
The Intel Arc B570 at $219, which runs 112 qualifying models.
How much VRAM do I need for fine-tuning a base model?
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.
