Can the RTX 5090 D run Qwen3 14B?
Yes. Qwen3 14B fits the RTX 5090 D's 32 GB at Q4_K_M (about 9.8 GB needed), running at an estimated 128 tok/s. There's room for up to FP16 if you want higher quality.

Qwen3 14B (14B) on 32 GB
| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 8 GB | 9.8 GB | Fits easily | ~128 tok/s |
| Q5_K_M | 10 GB | 11.8 GB | Fits easily | ~103 tok/s |
| Q8_0 | 16 GB | 17.8 GB | Fits easily | ~64 tok/s |
| FP16 | 28 GB | 29.8 GB | Tight | ~37 tok/s |
Estimates. Needs = weights + 1.8 GB for KV cache and runtime at modest context. Speed is single-stream decode scaled from the RTX 5090 D's 1790 GB/s bandwidth (Estimated from memory bandwidth (llama.cpp decode)). Long contexts need more memory and run slower.

Frequently asked
Quick answers
Can the GeForce RTX 5090 D run Qwen3 14B?
Yes. Qwen3 14B fits the RTX 5090 D's 32 GB at Q4_K_M (about 9.8 GB needed), running at an estimated 128 tok/s. There's room for up to FP16 if you want higher quality.
How much VRAM does Qwen3 14B need?
About 8 GB of weights at Q4_K_M, 16 GB at Q8_0 and 28 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.
How fast is Qwen3 14B on the RTX 5090 D?
Roughly 128 tokens per second at Q4_K_M (single user, llama.cpp-style decode). This is an estimate from the RTX 5090 D's 1790 GB/s memory bandwidth.
