Common questions

Can the NVIDIA DGX Spark run it?

Can the NVIDIA DGX Spark run Llama 3.3 70B?

Yes. Llama 3.3 70B needs about 45 GB and the NVIDIA DGX Spark with 128 GB of unified memory leaves about 96 GB for models. Expect about 3 tok/s, slow, but it works.

Can the NVIDIA DGX Spark run gpt-oss 120B?

Yes. gpt-oss 120B needs about 67 GB and the NVIDIA DGX Spark with 128 GB of unified memory leaves about 96 GB for models. Expect about 33 tok/s, faster than you can read.

Can the NVIDIA DGX Spark run Qwen3 235B-A22B?

No. Qwen3 235B-A22B needs about 144 GB and the NVIDIA DGX Spark has at most 128 GB of unified memory, of which about 96 GB is usable for models. The most capable model it runs well is gpt-oss 120B, at about 33 tok/s.

How we estimate

Generating a token reads the model's active weights from memory once, so speed is roughly memory bandwidth (273 GB/s) divided by the active weight size, with efficiency calibrated on our own rack. Sizes are Ollama's default 4-bit downloads plus about 1.2 GB for context. The GPU shares memory with the system, so we count about three quarters of it for models. Real results are usually within about a third. Measured runs are on the leaderboard.
