NVIDIA is reportedly preparing a notebook Arm-based SoC, the N1/N1X, and its specifications have leaked ahead of Computex.
The leak was first reported by VideoCardz, with Tom’s Hardware summarizing the information. However, some of the leaked data appears to be based on a 2024 document, so final product specifications may differ.
The key takeaway is that NVIDIA is not simply preparing a low-power Arm chip, but rather a high-performance notebook SoC with integrated CPU and large GPU.
The top-tier lineup, the N1X, is said to feature up to 20 Arm-based CPU cores and a 6,144 CUDA core GPU. This configuration appears to be similar to or even in the same family as the GB10 chip found in NVIDIA's DGX Spark.
The leaked N1X configuration is as follows:
Model | CPU Configuration | GPU Configuration | Power Range | Memory |
|---|
N1X High-End | 20 cores, 10+10 | 6,144 CUDA Cores | 45–80W | LPDDR5X, up to 128GB |
N1X Low-End | 18 cores, 9+9 | 5,120 CUDA Cores | 45–80W | LPDDR5X, up to 128GB |
The standard N1 appears to be a lower-power and more affordable model.
Model | CPU Configuration | GPU Configuration | Power Range | Memory |
|---|
N1 High-End | 12 cores, 8+4 | 2,560 CUDA Cores | 18–45W | LPDDR5X, up to 64GB |
N1 Low-End | 10 cores, 7+3 | 2,048 CUDA Cores | 18–45W | LPDDR5X, up to 64GB |
There are also differences in PCIe configurations. The N1X is said to offer PCIe 5.0 12 lanes and PCIe 4.0 5 lanes, supporting up to three M.2 SSDs. The standard N1 has a PCIe 5.0 8 lane and PCIe 4.0 3 lane configuration, supporting up to two M.2 SSDs.
Tom’s Hardware suggests that the N1X could be targeted at high-performance notebooks, particularly those competing with MacBook Pro or AMD Strix Halo models. The standard N1 is more likely to be a chip for thinner and more affordable Windows on Arm notebooks.
As this information is based on leaks before the official announcement, actual product specifications may vary in terms of clock speeds, memory speeds, power settings, and OEM configurations. However, judging by the leaked specs alone, NVIDIA appears to be making an aggressive move into the Windows on Arm notebook market.
In summary:
NVIDIA N1/N1X notebook Arm SoC specifications leaked
N1X features up to 20 cores CPU + 6,144 CUDA core GPU
N1 is a mid-range lineup with 10/12 core configurations
N1X power range: 45–80W; N1: 18–45W
LPDDR5X memory, N1X potentially supports up to 128GB
Potential for Windows on Arm notebooks, high-performance AI PCs, and MacBook Pro/Strix Halo competitors
