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.
- Shares the vision hard gate but weights structured-output ability higher (25% coding) and latency higher than general vision, because OCR is typically run in batch over many pages where throughput compounds.
FAQ
What is the best GPU for OCR and document scanning?
The AMD Radeon RX 7900 XTX — 24 GB of VRAM runs 50 qualifying models, the strongest being Gemma 4 (Withdrawn Listings).
What is the cheapest GPU that works for OCR and document scanning?
The Intel Arc B570 at $219, which runs 31 qualifying models.
How much VRAM do I need for OCR and document scanning?
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.
