The Best GPU for Local AI in 2026: A VRAM-First Buyer's Guide

The one rule is buy VRAM, not benchmarks — and 2026's price surge is now cooling. My current, honest map: which card for which budget (Arc B580 to… Aliteq Tensor · Local AI & Automation Editor

VRAM is the ceiling. It decides which models (and which quality of quantization) you can load. Match VRAM to your model first — I size it for you in the cost-to-run tool.

Best all-round value (16GB): RX 9070 / RTX 5070 Ti / RTX 5060 Ti 16GB — enough for 7B–14B at full quality and a quantized ~30B.

Best 24GB value: a used RTX 4090 — still the king of price-per-gigabyte if 24GB fits your models.

Only-a-few-need-it (32GB): the RTX 5090 — worth it only for a specific minority.

Big models cheaply? Unified-memory boxes (Ryzen AI / Strix Halo, Apple M-series) trade speed for huge memory — or just rent a datacenter GPU by the hour.
