Benchmarks & Specs

Last updated:
With the NVIDIA N1X, the manufacturer is bringing an interesting solution for modern systems to the market. Production takes place in the current 3 nm process, which significantly improves the efficiency of the entire hardware. We find the decision for the GB10 Grace / Blackwell architecture in this model particularly successful.

Especially the high memory bandwidth of 301 GB/s ensures rapid processing of large amounts of data in everyday life. Thanks to this enormous bandwidth, the chip delivers considerable AI performance for demanding applications and creative projects. An essential component is the integrated graphics unit called NVIDIA N1X (GB20B) for visual tasks.

Looking at the cache structure, the L2 cache with 24 MB and the L3 cache are striking. The latter, with 32 MB, offers enough buffer to effectively minimize delays in complex calculations. We have observed that the coordination between the components enables very harmonious performance. It is gratifying to see how NVIDIA consistently exploits the advantages of the new manufacturing technology here.

The processor dispenses with unnecessary baggage and instead focuses on high efficiency in operation. In our tests, system stability appeared consistently solid and absolutely reliable, even under prolonged load. For users who value modern standards, the NVIDIA N1X represents a solid basis. The combination of fast memory connection and modern architecture makes this chip a good choice.

We were surprised at how cool the system remains in compact cases despite the high computing power.
  • High AI performance through fast memory bandwidth
  • Modern architecture based on 3 nm technology
  • Integrated graphics unit for versatile visual applications
  • Generous cache for smooth workflows
