NVIDIA GB300 Grace Blackwell Ultra Desktop (DGX Station) — Benchmarks & Specs

2026

Short answer: the NVIDIA GB300 Grace Blackwell Ultra Desktop (DGX Station) generates 536 tokens/sec on gpt-oss:20b (MXFP4) under vllm in a single cited run, per StorageReview; there are too few comparable runs on file for a median.

Bottom line: how fast is the NVIDIA GB300 Grace Blackwell Ultra Desktop (DGX Station)?

In a batched serving run it reaches 536.0 tokens/sec aggregate throughput (many concurrent requests, not one user's generation speed) running gpt-oss:20b at MXFP4 under vllm, per StorageReview.

Every figure above is a row in the tables below, and each row links out to the review or public benchmark database the number was taken from. SpecPicks aggregates published measurements; it does not report first-party benchmark runs.

The NVIDIA GB300 Grace Blackwell Ultra Desktop (DGX Station) is an APU from the Grace Blackwell Ultra family released in 2026 from NVIDIA. Data on this page draws on 9 community AI inference reports, compiled from StorageReview; each table row links to its source. Read this page when shopping the NVIDIA GB300 Grace Blackwell Ultra Desktop (DGX Station), comparing it against other APUs in your build, or sizing it for a specific workload (local LLM inference).

AI Inference Performance

Tokens per second under each model + quantization. Higher = faster generation. Bars compare runs across the same model.

Local LLM inference throughput on the NVIDIA GB300 Grace Blackwell Ultra Desktop (DGX Station), in generated tokens per second for a single request (one user's generation speed). Higher is better; each row links to the community report or benchmark database it came from. Batched serving runs are listed separately below.

Batched serving throughput

Aggregate output tokens per second on the NVIDIA GB300 Grace Blackwell Ultra Desktop (DGX Station) summed across 128 concurrent requests (serving runtimes such as vLLM). This is total server throughput, not one user's generation speed — each request generates far slower — so these rows are not comparable with the single-stream table above.
