Best graphics cards for AI & Local LLMs — Value Ranking
A live value ranking of in-stock graphics cards for AI and local LLMs, scored by performance-per-dollar under the AI / LLM preset (snapshot 2026-07-14). The top pick right now is the RTX 5090.
What actually matters for AI and local LLMs
For local LLMs and diffusion models, VRAM capacity is the hard gate: the model either fits or it does not. 12GB runs quantized 7–13B models comfortably; 16GB opens 22–32B quants and serious SDXL/video work; 24GB+ is where 70B-class quants and larger context windows begin. After capacity, FP16/tensor throughput (our AI index) sets generation speed — and the software ecosystem still favors CUDA, so an otherwise-equal AMD card should be noticeably cheaper to win a spot in an AI build.
- VRAM capacity. The binary constraint: model + context + KV-cache must fit, or you fall back to slow offloading.
- AI/tensor index. FP16 tensor throughput (RTX 4070 = 1000 scale) — the speed of everything once the model fits.
- Ecosystem. CUDA remains the default path for most tooling; ROCm/Vulkan backends are improving but budget extra setup time.
- Dual use. These same cards rank high for 4K — check the ranking under both presets before spending.
