Can the DGX Spark (GB10) run Qwen3-30B-A3B-Instruct-2507?
Yes. Qwen3-30B-A3B-Instruct-2507 fits the DGX Spark (GB10)'s 128 GB at Q4_K_M (about 19.8 GB needed), running at an estimated 59 tok/s. There's room for up to FP16 if you want higher quality.

| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 18 GB | 19.8 GB | Fits easily | ~59 tok/s |
| Q5_K_M | 22 GB | 23.8 GB | Fits easily | ~48 tok/s |
| Q8_0 | 33 GB | 34.8 GB | Fits easily | ~32 tok/s |
| FP16 | 61 GB | 62.8 GB | Fits easily | ~17 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 Qwen3-30B-A3B-Instruct-2507?
Yes. Qwen3-30B-A3B-Instruct-2507 fits the DGX Spark (GB10)'s 128 GB at Q4_K_M (about 19.8 GB needed), running at an estimated 59 tok/s. There's room for up to FP16 if you want higher quality.
How much VRAM does Qwen3-30B-A3B-Instruct-2507 need?
About 18 GB of weights at Q4_K_M, 33 GB at Q8_0 and 61 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.
How fast is Qwen3-30B-A3B-Instruct-2507 on the DGX Spark (GB10)?
Roughly 59 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; as a mixture-of-experts model only about 3B parameters are read per token, which is why it is faster than its size suggests.
