NVIDIA N1X: 20-Core ARM Processor Challenges Desktop High-Ends
Competitive performance in Geekbench tests, Blackwell architecture with 10 Cortex-X925 and integrated GPU with 6144 CUDA cores: the N1X positions itself among the flagship solutions from Intel, AMD
Isabella V11 June 2025
A 20-core NVIDIA N1X ARM processor emerges with Geekbench results of 3096 points in single-core and 18837 in multi-core, obtained on an HP board with Ubuntu24.04. The architecture is based on the GB10 (10× Cortex-X925 + 10× Cortex-A725) with frequencies up to ~4GHz and 128GB of RAM (8 dedicated to the integrated Blackwell GPU with ~6144 CUDA cores). Performance places it among the best current desktop/laptop on ARM x86, potentially superior to RyzenAI, Snapdragon and close to Intel Core Ultra9. The consumer launch date remains uncertain (maybe 2026), while GB10 is expected in July 2025.
Key points:
- Geekbench benchmark: 3096 single-core and 18837 multi-core, on Linux 6.2.2.
- ARM big.LITTLE configuration: 10 Cortex-X925 + 10 Cortex-A725, freq ~2.81–4GHz.
- Test system: HP “8EA3” board, Ubuntu 24.04, 128GB RAM (8GB per GPU).
- Blackwell integrated GPU: about 6144 CUDA cores (equivalent to RTX5070 series).
The processor, the result of a collaboration between NVIDIA and MediaTek, appears to be based on the GB10 Superchip already announced for AI solutions such as DGX Spark, and aims to position itself in the Windows-on-ARM desktop and laptop segment. In the Geekbench 6.2.2 benchmark, the N1X outclasses the Snapdragon X Elite, holds its own against the RyzenAI MAX+395 and approaches the Intel Core Ultra9 285HX, while remaining behind the Apple M4 Max. Although rumors indicate a delayed debut to 2026, NVIDIA could anticipate a mass market release at the same time or after the AI release of the GB10 scheduled for July 2025. At the moment, important parameters such as TDP, software optimization, Windows compatibility and implications in the performance-energy ratio remain unclear.
It is an interesting preview of NVIDIA’s ARM ambitions, marked by advanced technical capabilities and competitive potential. The N1X offers a concrete look at NVIDIA’s capabilities in forming a powerful ARM alternative even in the consumer segment.
