Pros & Cons

Pros

✓ 2.2-slot compact form factor fits SFF cases that triple-slot RTX 4070 cards will not
✓ Factory OC to a 2490 MHz boost clock, no manual tuning required
✓ 12GB GDDR6X running at 21 Gbps for 1440p texture headroom
✓ DLSS 3 frame generation plus 3rd-gen RT cores for ray-traced titles

Which local LLMs fit in 12 GB?

12 GB holds models up to about 14B at Q4 with a usable context window; above that band the weights spill to system RAM and PCIe bandwidth sets the speed, not the GPU.

✅ 7–9B models (Llama 3.1 8B, Qwen 3 8B) — fits at Q4
✅ 12–14B models (Qwen 3 14B, Phi-4) — fits at Q4
❌ 20–27B models (Gemma 3 27B, Mistral Small) — needs 20 GB+
❌ 30–35B models (Qwen 3 32B, QwQ 32B) — needs 24 GB+
❌ 70B models (Llama 3.3 70B, Qwen 2.5 72B) — needs 48 GB+

Across 8 community runs from 8 sources, the GeForce RTX 4070 generates a median 77.2 tok/s on 7–9B models at Q4 (per Ajit Singh / Hardware Corner).
