Best GPU for Local AI Reasoning
作者： Jakub Rusinowski · 最后更新： 2026年10月7日
Ranked for reasoning and multi-step problem solving: Problems that need explicit multi-step thinking: planning, analysis, and chains of inference rather than recall.
Best overall: Intel Arc B580
12 GB VRAM at 456 GB/s. It runs 92 of the models that qualify for this workload; the strongest is Qwen 3 14B at an estimated 33 tokens/sec.

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 score dominates at 75%. The quality floor is the strictest of any workload (65) because a weak reasoning model is not merely slower — it is confidently wrong. Latency is deliberately down-weighted to 0.3: reasoning models emit long thinking traces, so tokens/sec matters less than whether the conclusion is right.
FAQ
What is the best GPU for reasoning and multi-step problem solving?
The Intel Arc B580 — 12 GB of VRAM runs 92 qualifying models, the strongest being Qwen 3.
What is the cheapest GPU that works for reasoning and multi-step problem solving?
The Intel Arc B570 at $219, which runs 91 qualifying models.
How much VRAM do I need for reasoning and multi-step problem solving?
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.
