Compatibility check
Can you run Qwen2.5 14B Instruct on the RTX 4060 Ti 8GB?
Not on a single RTX 4060 Ti 8GB. Even at 4-bit, Qwen2.5 14B Instruct needs about 9.3 GB, which exceeds the card's 8 GB. You would need roughly 2× RTX 4060 Ti 8GB with tensor parallelism, a larger GPU, or a smaller model.
Memory breakdown
Weights plus a 0.8 GB KV cache at 4,096tokens, against the card's 8 GB. Verdicts leave ~10% headroom for activations and fragmentation.
| Precision | Weights | KV cache | Total | % of 8 GB | Fit |
|---|---|---|---|---|---|
| FP16 / BF16full quality | 34 GB | 0.8 GB | 34.8 GB | 435% | No |
| INT8 (8-bit)near-full quality | 17 GB | 0.8 GB | 17.8 GB | 223% | No |
| INT4 (4-bit)GPTQ / AWQ / GGUF Q4 | 8.5 GB | 0.8 GB | 9.3 GB | 116% | No |
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 4060 Ti 8GB run Qwen2.5 14B Instruct?
No. Even 4-bit needs about 9.3 GB, more than the 8 GB available.
How much VRAM does Qwen2.5 14B Instruct need?
Approximately 34 GB in FP16, 17 GB in INT8, and 8.5 GB in 4-bit for the weights, plus a KV cache of about 0.8 GB at 4,096 tokens.
Does quantization let Qwen2.5 14B Instruct fit on the RTX 4060 Ti 8GB?
Not on a single RTX 4060 Ti 8GB — even 4-bit exceeds 8 GB. You would need multiple GPUs or a larger card.
What happens to memory with longer context?
The KV cache grows linearly with prompt length. At 4,096 tokens it is about 0.8 GB here; doubling the context roughly doubles that term, so long-context use can push a tight fit over the edge.
