How much VRAM does Mistral 7B v0.3 need?
Mistral 7B v0.3 needs about 5.0 GB of VRAM at Q4_K_M, or 8.3 GB at Q8_0 and 14.9 GB at FP16. That fits a consumer card: the smallest in our set that holds it at Q4_K_M is the RTX 3060 12GB (12 GB). Weights plus runtime overhead; KV cache for your context length is on top.
Weights-plus-runtime footprint across the six most common quantizations. KV cache is context-dependent and comes on top. Filled to this model's 32K window it can rival the weights themselves; size it for your context in the GPU Memory Calculator.
This is the base checkpoint: pretrained on raw text and not tuned to follow instructions, so it continues text rather than answering prompts. That makes it the right starting point if you plan to fine-tune your own model. For chat or assistant work, use Mistral 7B v0.3 Instruct — same parameter count, so the memory figures below are identical.
Can your GPU run Mistral 7B v0.3?
Pick your card — the answer below is computed by the same engine that produces every figure on this page.
RTX 3060 12GB runs Mistral 7B v0.3 at Q4_K_M with 6.4 GB to spare; plenty of room for a long context window or a second model alongside it.
Weights plus runtime overhead. KV cache is not included — it depends on context length and this model’s published architecture.
| Weights (Q4_K_M) | 4.1 GB |
| Runtime overhead | 1.0 GB |
| Estimated total | 5.0 GB |
| Usable VRAM (95% of 12 GB) | 11.4 GB |

How was this number calculated? Every figure here comes from Bitpute’s documented calculation methodology — parameters, precision, quantization, runtime overhead and usable VRAM, each formula written out in full.
Memory by quantization
| Quant | Weights | + runtime overhead |
|---|---|---|
| FP16 | 13.5 GB | 14.9 GB |
| Q8_0 | 7.2 GB | 8.3 GB |
| Q6_K | 5.5 GB | 6.6 GB |
| Q5_K_M | 4.8 GB | 5.8 GB |
| Q4_K_M | 4.1 GB | 5.0 GB |
| Q4_0 | 3.8 GB | 4.7 GB |
Overhead = 0.75 GB + 5% of weights (CUDA context, buffers). Add KV cache on top. At this model's full 32K window it can rival the weights.
Which quantization should you actually run?
Mistral 7B v0.3 fits a 12 GB card at Q8_0 (8.3 GB) with essentially no quality loss, with room for everyday context lengths. Q4_K_M (5.0 GB) frees more memory at minimal cost; full FP16 (14.9 GB) only pays off on RTX 4090.

Where the memory goes
Weights and overhead are exact for Q4_K_M. The KV bar is a generic 32-layer transformer at 8K — on a model this small it is the term that decides whether you fit, so check yours in the calculator is for.

Common questions
How much VRAM does Mistral 7B v0.3 need?
Mistral 7B v0.3 needs about 5.0 GB of VRAM at Q4_K_M, 8.3 GB at Q8_0, or 14.9 GB at FP16. That is weights plus about 0.75 GB of runtime overhead and 5% of weight size; KV cache is additional and depends on context length.
What GPU can run Mistral 7B v0.3?
At Q4_K_M the smallest card in our set that fits is the RTX 3060 12GB (12 GB usable at 95%). At FP16 you need the RTX 4060 Ti 16GB (16 GB) or larger.
Can Mistral 7B v0.3 run on 24 GB?
Yes. At Q4_K_M it needs about 5.0 GB, which fits inside the ~22.8 GB usable on a 24 GB card.
Same memory footprint as 5 other checkpoints
Mistral 7B v0.3 has an identical parameter count to these, so every figure on this page applies to them unchanged. What varies is different checkpoint roles (instruction-tuned) and a different release of the same base build — not the size. Choose on capability and licence; the memory budget is identical.
