Want to run 70B models?

A 70B model at Q4 needs about 48 GB of VRAM — more than the RTX 3070's 8GB. The cheapest single card that runs Llama 3.3 70B fully on-GPU is the Apple M5 Pro (64GB) (54GB). Check Apple M5 Pro (64GB) prices on Amazon →

Or skip the hardware: rent a Apple M5 Pro (64GB)-class GPU by the hour and run 70B today. RunPod · Vast.ai

RTX 3070 FAQ

What's the biggest LLM an RTX 3070 can run?

Fully on-GPU at 8K context, the biggest model that fits the RTX 3070 (8GB) is Qwen3.5 9B at Q5_K_M (~57 tok/s). Larger models need a card with more VRAM or system-RAM offload, which is much slower.

How fast is an RTX 3070 for local AI?

On a mid-size model like Llama 3.1 8B (Q5_K_M), expect roughly 56 tokens/sec. Speed scales with memory bandwidth (448 GB/s) more than anything else.

Can an RTX 3070 run a 70B model?

Not fully on-GPU: a 70B at Q4 needs about 48 GB and the RTX 3070 has 8GB. It can crawl with system-RAM offload, but a bigger card or a rented cloud GPU is the practical route.

Is the RTX 3070 good for local AI in 2026?

It runs 16 of the 51 models we track — a workable entry point for small and mid-size models. The full breakdown is in the table above.
