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.
Weighted like a coding workload with the licence sensitivity of an enterprise one, and a long-context floor for log and diff analysis. The reason this workload runs locally at all is usually that the material cannot leave the network, which is why licence weight is high (0.7).

FAQ

What is the best GPU for security analysis and defensive research?

The AMD Ryzen AI Max+ 395 — 96 GB of VRAM runs 97 qualifying models, the strongest being Qwen 3.7.

What is the cheapest GPU that works for security analysis and defensive research?

The Intel Arc B570 at $219, which runs 59 qualifying models.

How much VRAM do I need for security analysis and defensive research?

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.
