RTX 5070 vs RTX 4070: which GPU for local LLMs?
A buy-focused comparison for running LLMs locally. What matters: VRAM first, then generation and price.
At a glance
| Spec | RTX 5070 | RTX 4070 |
|---|---|---|
| VRAM | 12 GB | 12 GB |
| Compatible models (Q4) | 111 | 111 |
| Largest model (Q4) | Granite Code 20B (Mixed Precision) | Granite Code 20B (Mixed Precision) |
Which one should you buy?
For larger models (a 70B at Q4, or a comfortable 30B), pick the RTX 5070 and its 12 GB — VRAM is the #1 factor for local LLMs. The RTX 4070 is the pick on a tighter budget or for models up to its 12 GB. Rule of thumb: at equal budget, always take more VRAM.
