What is the best GPU for running local AI in 2026?

The RTX 5070 is the best GPU for local AI in 2026. It has 12 GB GDDR7 memory at 672 GB/s bandwidth — the highest bandwidth-per-dollar on the market — and achieves ~120 tokens per second on Llama 3.1 8B.

How much VRAM do I need for local AI?

You need at least 8 GB VRAM for 7B models (Q4 quantized), 12–16 GB for 13B models, and 40+ GB for 70B models. Memory bandwidth matters as much as capacity — more GB/s means faster token generation.

Is AMD or NVIDIA better for local AI?

NVIDIA is better for Windows users due to broader software support. AMD GPUs (RX 9060 XT, RX 7900 XTX) work well on Linux with ROCm but have limited Windows compatibility for AI workloads.

Best GPUs for Local AI

Memory bandwidth matters more than CUDA cores. More GB/s = more tokens per second.
