Nvidia N1 and N1X Arm chips leak ahead of launch, promising powerful Windows laptops with Blackwell graphics
Nvidia’s long-rumored push into Arm-based PC processors may be closer than ever. Fresh leaked specifications suggest the company is preparing a new N1-series lineup designed for laptops and compact PCs, combining modern Arm CPU cores with powerful Blackwell graphics in a single package.
The upcoming family is expected to include at least four chip configurations. At the top sits the N1X series, aimed at premium performance laptops and workstation-class portable systems. Below that, the standard N1 chips appear to be designed for thinner, more affordable devices that still need strong graphics and AI capabilities.
The flagship Nvidia N1X is reportedly built around a 20-core CPU layout. This configuration includes 10 Cortex-X925 performance cores and 10 Cortex-A725 efficiency cores, giving it a balanced mix of raw speed and power management. On the graphics side, the chip is said to feature a Blackwell 2.0 GPU with 48 Streaming Multiprocessors, which equals 6,144 CUDA cores.
That level of integrated GPU power could make the N1X a major step forward for Arm-based Windows laptops, especially for users interested in gaming, content creation, AI workloads, and GPU-accelerated applications.
A second N1X model is also said to be in development. This slightly reduced version reportedly uses an 18-core CPU with a 9 performance core and 9 efficiency core setup. Its integrated Blackwell GPU may include 40 Streaming Multiprocessors, or 5,120 CUDA cores. Both N1X variants are expected to operate within a 45 W to 80 W power range.
What makes this especially interesting is that the power figure reportedly covers the complete CPU and GPU package, rather than just the processor alone. That could make Nvidia’s design highly competitive in high-end laptop systems where performance per watt is increasingly important.
The standard Nvidia N1 lineup appears to target mainstream laptops, slim notebooks, and more affordable Arm-based PCs. The stronger N1 model is said to include 12 CPU cores, made up of 8 Cortex-X925 performance cores and 4 Cortex-A725 efficiency cores. Its GPU reportedly features 20 Streaming Multiprocessors, delivering 2,560 CUDA cores.
A second standard N1 chip may offer a 10-core CPU configuration with 7 performance cores and 3 efficiency cores. This model is expected to include a 16-SM GPU with 2,048 CUDA cores. These chips are reportedly designed for a lower 18 W to 45 W power range, making them better suited for thin-and-light laptops with longer battery life.
Memory support may be one of the biggest differences between the N1X and N1 families. The higher-end N1X chips are said to support up to 128 GB of LPDDR5X memory using a 16-channel interface. That would give premium systems plenty of bandwidth for demanding creative, AI, and graphics-heavy workloads.
The standard N1 chips reportedly support up to 64 GB of LPDDR5X memory through an 8-channel interface. Storage support also appears to vary by tier, with N1X platforms said to support up to three M.2 SSDs, while N1 systems may support up to two.
The leaked material suggests Nvidia has been working on this Arm PC platform for a considerable amount of time. Some internal information reportedly dates back to 2024, indicating that development may have been underway for years before the expected public reveal.
As with all pre-release information, the final retail products may differ from these leaked specifications. Some listed configurations may be changed, renamed, delayed, or never released. Still, the details point to a serious and ambitious effort from Nvidia to enter the PC processor market in a much bigger way.
If these specifications are accurate, the Nvidia N1 and N1X chips could become a major new force in the Windows-on-Arm laptop segment. By pairing Arm CPU cores with Blackwell-based graphics and strong memory support, Nvidia may be preparing a platform that challenges traditional laptop processors while offering powerful GPU and AI performance in compact devices.
The timing is also important. With interest in AI PCs, efficient laptops, and Arm-based Windows devices continuing to grow, Nvidia’s N1 series could arrive at exactly the right moment. If laptop makers adopt the platform widely, future Nvidia-powered notebooks may offer a compelling mix of battery life, performance, gaming capability, and AI acceleration.
