Can the DGX Spark (GB10) run Qwen3 32B?
Yes. Qwen3 32B fits the DGX Spark (GB10)'s 128 GB at Q4_K_M (about 20.8 GB needed), running at an estimated 8.3 tok/s. There's room for up to FP16 if you want higher quality.

| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 19 GB | 20.8 GB | Fits easily | ~8.3 tok/s |
| Q5_K_M | 23 GB | 24.8 GB | Fits easily | ~6.8 tok/s |
| Q8_0 | 34 GB | 35.8 GB | Fits easily | ~4.6 tok/s |
| FP16 | 64 GB | 65.8 GB | Fits easily | ~2.5 tok/s |
Estimates. Needs = weights + 1.8 GB for KV cache and runtime at modest context. Speed is single-stream decode scaled from the DGX Spark (GB10)'s 273.2 GB/s bandwidth (Estimated from memory bandwidth (llama.cpp decode)). Long contexts need more memory and run slower.

Frequently asked
Quick answers
Can the NVIDIA DGX Spark (GB10) run Qwen3 32B?
Yes. Qwen3 32B fits the DGX Spark (GB10)'s 128 GB at Q4_K_M (about 20.8 GB needed), running at an estimated 8.3 tok/s. There's room for up to FP16 if you want higher quality.
How much VRAM does Qwen3 32B need?
About 19 GB of weights at Q4_K_M, 34 GB at Q8_0 and 64 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.
How fast is Qwen3 32B on the DGX Spark (GB10)?
Roughly 8.3 tokens per second at Q4_K_M (single user, llama.cpp-style decode). This is an estimate from the DGX Spark (GB10)'s 273.2 GB/s memory bandwidth.
