Compatibility check
Can you run Mistral 7B Instruct v0.3 on the RTX 3060?
Yes, with quantization. Mistral 7B Instruct v0.3 does not fit the RTX 3060 (12 GB) in FP16, but it runs at INT8 (8-bit) using about 8.8 GB (73% of VRAM). Use a GPTQ, AWQ, or GGUF build to get there, and keep prompts moderate to leave room for the KV cache.
Memory breakdown
Weights plus a 0.5 GB KV cache at 4,096tokens, against the card's 12 GB. Verdicts leave ~10% headroom for activations and fragmentation.
| Precision | Weights | KV cache | Total | % of 12 GB | Fit |
|---|---|---|---|---|---|
| FP16 / BF16full quality | 16.7 GB | 0.5 GB | 17.2 GB | 143% | No |
| INT8 (8-bit)near-full quality | 8.3 GB | 0.5 GB | 8.8 GB | 73% | Fits |
| INT4 (4-bit)GPTQ / AWQ / GGUF Q4 | 4.2 GB | 0.5 GB | 4.7 GB | 39% | Fits |
Planning estimates, not a substitute for profiling. Real usage varies with the inference runtime, batch size, and how much context you actually use — the KV cache grows linearly with prompt length.

Frequently asked questions
Can the RTX 3060 run Mistral 7B Instruct v0.3?
Not in FP16, but yes at INT8 (8-bit), where it uses about 8.8 GB versus the card's 12 GB.
How much VRAM does Mistral 7B Instruct v0.3 need?
Approximately 16.7 GB in FP16, 8.3 GB in INT8, and 4.2 GB in 4-bit for the weights, plus a KV cache of about 0.5 GB at 4,096 tokens.
Does quantization let Mistral 7B Instruct v0.3 fit on the RTX 3060?
Yes. Dropping to INT8 (8-bit) brings total usage to about 8.8 GB, which fits the 12 GB card with headroom for the KV cache.
What happens to memory with longer context?
The KV cache grows linearly with prompt length. At 4,096 tokens it is about 0.5 GB here; doubling the context roughly doubles that term, so long-context use can push a tight fit over the edge.
