Pixtral 12B needs ~9.1 GB VRAM. RTX 2070 Super 8GB has 8.0 GB. With Q2_K quantization, expect ~29 tok/s.
Operating mode
Interactive favors responsiveness, while light API and scale-out lean harder on serving readiness. The fit stays the same, but the recommendation lens changes.
Current mode
Balanced
Balanced for general local use. Keeps the ranking neutral across personal and serving workflows.

Offload
30%
It fits through host-memory offload, and offload is the main reason performance drops.
CPU or host-memory offload is active
About 10% of the working set spills out of accelerator memory, which usually hurts latency and sustained decode throughput.
Very little memory headroom
You can run the model, but there is not much room left for longer context, bigger batches, extra apps, or future model updates.
Older PCIe generation
PCIe 3.0 is workable, but it compounds the penalty when you offload heavily or try to scale across multiple cards.
Remove offload with more accelerator memory
Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.
Increase host RAM if you keep offloading
This setup may need roughly 0.6 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Yes, RTX 2070 Super 8GB can run Pixtral 12B at Q2_K quantization (Very compromised (needs ~0.6 GB host RAM)). The recommended Q4_K_M requires 11.8 GB which exceeds available memory, but at Q2_K it needs only 9.1 GB. Expected decode speed: 29.2 tok/s.
Pixtral 12B (12B parameters) requires approximately 11.8 GB at Q4_K_M quantization. On RTX 2070 Super 8GB, it fits at Q2_K using 9.1 GB.
The recommended quantization is Q4_K_M, but on RTX 2070 Super 8GB the best fitting quantization is Q2_K, which uses 9.1 GB.
On RTX 2070 Super 8GB, Pixtral 12B achieves approximately 29.2 tokens per second decode speed with a time-to-first-token of 6635ms using Q2_K quantization.
For coding workloads, Pixtral 12B on RTX 2070 Super 8GB receives a F grade with 12.6 tok/s and 4K context.
On RTX 2070 Super 8GB, Pixtral 12B can safely use up to 9K tokens of context at Q2_K quantization. The model's official context limit is 131K, but available memory constrains the safe maximum.
