Newly leaked specifications have provided the clearest look yet at NVIDIA’s upcoming N1-series laptop processors, including the flagship N1X chip expected to power next-generation AI-focused Windows notebooks.
According to details published by VideoCardz, the top-end N1X processor is said to feature the same core configuration as NVIDIA’s GB10 Superchip used in the DGX Spark AI system. The chip reportedly combines 10 high-performance Arm Cortex-X925 cores with 10 Cortex-A725 efficiency cores, delivering a total of 20 CPU cores.
The leak also suggests that the flagship variant will include 48 Streaming Multiprocessors (SMs), equivalent to 6,144 CUDA cores, making it one of the most powerful integrated GPU solutions ever seen in a laptop processor.
| Model | CPU Cores | GPU (SMs) | CUDA Cores | Memory Support | TDP |
|---|---|---|---|---|---|
| N1X (Full) | 20 (10X + 10A) | 48 | 6,144 | Up to 128GB LPDDR5X | 45W–80W |
| N1X (Cut-Down) | 18 (9X + 9A) | 40 | 5,120 | Up to 128GB LPDDR5X | 45W–80W |
| N1 | 12 | 20 | 2,560 | Up to 64GB LPDDR5X | 18W–45W |
| N1 (Lower Variant) | 10 | 16 | 2,048 | Up to 64GB LPDDR5X | 18W–45W |
The report indicates that N1X-powered systems may support up to 128GB of LPDDR5X memory and multiple PCIe 5.0 lanes, positioning the platform for high-end AI workloads, content creation, and workstation-class laptops.
Meanwhile, the standard N1 models appear aimed at thinner and more mainstream notebooks, offering lower power consumption while retaining NVIDIA’s integrated Blackwell-based graphics architecture.
The leak comes as NVIDIA, Microsoft and Arm Holdings have teased major PC-related announcements ahead of Computex 2026, fueling speculation that NVIDIA is preparing to formally enter the Windows-on-Arm laptop market.
Although the specifications remain unofficial, the leaked details suggest NVIDIA is targeting both premium AI workstations and mainstream laptops with its first generation of Arm-based PC processors.
