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.
- The only workload where the creative score dominates (65%). The quality floor is deliberately the lowest of any profile (45): prose quality correlates weakly with reasoning benchmarks, so excluding models on an aggregate index would discard genuinely good writing models.
FAQ
What is the best GPU for writing and editing?
The NVIDIA GeForce RTX 5070 Ti — 16 GB of VRAM runs 123 qualifying models, the strongest being Mistral Small 3.1.
What is the cheapest GPU that works for writing and editing?
The Intel Arc B570 at $219, which runs 112 qualifying models.
How much VRAM do I need for writing and editing?
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.
