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.
- Reliable structured tool calls are a hard gate here, not a bonus: a model with no tool-use tag is excluded regardless of score. Coding weight is high (40%) because tool arguments are effectively code. Context needs match RAG — an agent loop accumulates every observation it has ever seen.
FAQ
What is the best GPU for autonomous agents and tool use?
The Intel Arc B570 — 10 GB of VRAM runs 19 qualifying models, the strongest being Bonsai 27B.
What is the cheapest GPU that works for autonomous agents and tool use?
The Intel Arc B570 at $219, which runs 19 qualifying models.
How much VRAM do I need for autonomous agents and tool use?
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.
