Can I run Qwen2.5-Coder-14B-Instruct on a RTX A2000?

Q: Can I run Qwen2.5-Coder-14B-Instruct on a RTX A2000?

No. No published quantization of Qwen2.5-Coder-14B-Instruct fits a RTX A2000 at any context with q8_0 KV cache.

Not at these settings. No indexed quantization of Qwen2.5-Coder-14B-Instruct fits RTX A2000 at any context we compute, with q8_0 KV. The smallest shipped quantization is 4.38 GiB in weights alone, against 5.58 GiB usable. CPU offload can still run it, slowly.

●From the file◐Predictedwhat these mean

Figures are GiB of total memory: weights plus KV cache plus compute buffer and backend overhead. Weights and KV are near-exact; the overhead term is modeled. Hover any cell for the breakdown.

Why other calculators disagree

A parameters × bits ÷ 8 estimate ignores two things that dominate at long context. First, the weights themselves are not the nominal rate — quantizations are mixtures, so the real file is consistently larger than the label implies. Second, most of this model's layers cache only a 131,072-token window rather than the full context.
