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.
- Reasoning-led (70%) with a 32K context floor, because a single paper with references routinely exceeds 30K tokens. Latency is down-weighted to 0.3 — research reading is not interactive in the way chat is.
FAQ
What is the best GPU for research and technical reading?
The NVIDIA GeForce RTX 5090 — 32 GB of VRAM runs 115 qualifying models, the strongest being Gemma 4.
What is the cheapest GPU that works for research and technical reading?
The Intel Arc B570 at $219, which runs 78 qualifying models.
How much VRAM do I need for research and technical reading?
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.
