NVIDIA RTX Spark (N1X) 20-Core — Benchmarks & Specs

2026

Short answer: the NVIDIA RTX Spark (N1X) 20-Core generates 37.7 tokens/sec on nemotron-3.5-bolt:74b under lm-studio in a single cited run, per Wccftech; there are too few comparable runs on file for a median.

Bottom line: how fast is the NVIDIA RTX Spark (N1X) 20-Core?

At 1440p High with DLSS Quality upscaling, the NVIDIA RTX Spark (N1X) 20-Core averages 67 fps in Forza Horizon 6, per Wccftech. For local LLM inference it generates 37.7 tokens/sec running nemotron-3.5-bolt:74b under lm-studio (the source did not report the machine's memory configuration), per Wccftech. Unified memory is the binding constraint for local inference: the NVIDIA RTX Spark (N1X) 20-Core ships in configurations of up to 128 GB, per the manufacturer spec sheet, and a 74B model at 4-bit needs roughly 45 GB for its weights alone (74B parameters at ~4.85 bits per weight, per llama.cpp), so it runs only on configurations with more unified memory than that. In 3DMark Night Raid it scores 56,326 points, per Wccftech.

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; the memory ceiling and the weight-size estimate are not table rows and link to their sources inline. SpecPicks aggregates published measurements; it does not report first-party benchmark runs.

The NVIDIA RTX Spark (N1X) 20-Core is an APU from the RTX Spark family released in 2026 from NVIDIA. Key on-paper specs include 20 CPU cores, 6144 GPU cores, up to 128 GB of unified memory. Data on this page draws on 18 synthetic benchmark results (top 10 shown), 12 community AI inference reports, 5 measured game frame-rate results, compiled from Wccftech, StorageReview, Notebookcheck; each table row links to its source. Read this page when shopping the NVIDIA RTX Spark (N1X) 20-Core, comparing it against other APUs in your build, or sizing it for a specific workload (gaming at 1080p/1440p/4K, synthetic benchmark scores, or local LLM inference).
