What limits this combo
The four constraints the fit engine checks for Mistral Nemo 12B on the RTX 4070, in order of what usually breaks first.
Where the RTX 4070 sits for Mistral Nemo 12B
On the RTX 4070, Mistral Nemo 12B runs with room to spare (~37 tok/s est.). The cheapest card that also runs it comfortably is the RTX 3060 (12 GB, ~30 tok/s est.).
Same engine as the verdict above: 90% of VRAM usable, KV-cache at fp16, bandwidth-derived tok/s. Verdicts of the other cards are computed for Mistral Nemo 12B Q4_K_M exactly.
Quant explorer
Switch between the quality-gated builds tracked for this exact combo. Q4_K_M stays the default recommendation; heavier Q6/Q8 builds only appear when their exact Ollama tags are registry-verified.
Why no 2-bit builds: Q1/Q2-class quants can look attractive in a memory table, but their quality loss is large enough that ModelFit excludes them from rankings instead of inflating the catalog with junk options. Usable VRAM: 10.8 GB.
Workload verdicts
Mistral Nemo 12B on the RTX 4070, graded per use case from the model's registry-verified tuning and the engine's speed estimate for this exact combo.
Grades combine tag-verified tuning (a model not built for the workload caps at C) with the tok/s floor each workload needs to feel usable. A combo that partially offloads caps at C; one that does not fit is D everywhere.
Memory math: weights + context vs budget
Weights take 9.5 GB. Context costs extra KV-cache on top; this is where long-context sessions break on cards that technically fit the weights.
This configuration exceeds the comfortable VRAM budget by about 1.7 GB. Expect offload pressure or a shorter safe context.
KV-cache figures assume an fp16 cache, the llama.cpp/Ollama default. Standard GQA models use a size-class estimate (8 KV heads x 128 head dim class); hybrid linear-attention models (Qwen3.5/3.6, Qwen3-Next) use the exact per-token cost from their published config, since only their sparse full-attention layers cache KV. A q8_0 KV cache roughly halves either figure. Estimates, not measurements.

Mistral Nemo 12B on RTX 4070: FAQ
Can the NVIDIA GeForce RTX 4070 run Mistral Nemo 12B?
Yes. Mistral Nemo 12B (Q4_K_M) loads in about 9.5 GB and the RTX 4070 offers 10.8 GB of usable VRAM, leaving headroom for context. Expect at roughly 37 tokens/sec (est.).
How much VRAM does Mistral Nemo 12B need?
About 9.5 GB for the weights at Q4_K_M, plus KV-cache for context: roughly 3.0 GB extra at 16k tokens. The RTX 4070 budget is 10.8 GB (12 GB x 90%).
What is the best quantization of Mistral Nemo 12B for the RTX 4070?
Stick with the Q4_K_M build at 9.5 GB; every heavier quant exceeds the 10.8 GB usable VRAM.
What GPU do I need to run Mistral Nemo 12B comfortably?
The RTX 4070 already runs Mistral Nemo 12B comfortably. Larger cards only buy you longer context or a heavier quant.
How much context can Mistral Nemo 12B use on the RTX 4070?
None worth having: the 9.5 GB of weights alone exceed the 10.8 GB usable VRAM, so the model only runs with system-RAM offload and short prompts.
Is Mistral Nemo 12B on the RTX 4070 fast enough for coding agents?
Barely on paper: the engine estimates ~37 tok/s against the ~30 tok/s an agentic loop needs to feel responsive, but Mistral Nemo 12B is not tuned for tool-calling, which caps its agentic grade; a coding-tuned model is the better pick here.
