NVIDIA’s next move in laptop chips is starting to look more ambitious than a typical ARM platform refresh. New leaks around N1 and N1X suggest the company is preparing a pair of laptop processors that combine ARM CPU cores with Blackwell graphics, high memory capacity, and power targets aimed at very different device classes.
The standout name is N1X, which is being positioned far above a standard efficiency-focused notebook chip. According to the reported specifications, its graphics capability is close to a midrange discrete GPU, with performance said to be in the territory of an RTX 5070-class part.
A laptop chip with unusually strong graphics
The most striking detail around N1X is the GPU configuration. The chip is said to use NVIDIA’s Blackwell architecture with 48 SMs, or 6,144 CUDA cores, which is why it is being linked to RTX 5070-level performance.
That level of graphics power places N1X in a very different category from typical integrated laptop silicon. Instead of treating graphics as a secondary feature, NVIDIA appears to be building N1X as a platform for performance-focused portable systems.
Different power targets for different devices
One reason the laptop version is drawing attention is its much lower power target compared with the system that first surfaced with the chip. The initial known product using N1X is DGX Spark, a compact AI supercomputer that runs at 140W.
The laptop version is reported to be configurable between 45W and 80W. That adjustment is clearly meant to make the chip practical for notebook cooling and battery-constrained designs.
CPU design shifts for the notebook version
The laptop variant is also said to use a different CPU arrangement from the DGX Spark model. Instead of NVIDIA’s custom Grace cores, the notebook version reportedly uses 20 ARM cores in total.
That layout consists of 10 Cortex-X925 performance cores and 10 Cortex-A725 efficiency cores. The same reports indicate that the rest of the platform stays largely unchanged outside the CPU design.
A lower N1X variant is also in the works
Alongside the full version, there is said to be a trimmed N1X configuration as well. This cut-down model reportedly carries 18 ARM cores and a smaller GPU with 40 SMs, equal to 5,120 CUDA cores.
Even with the reduced configuration, both N1X versions are said to support 12 lanes of PCIe 5.0 and 5 lanes of PCIe 4.0. Memory support remains substantial too, with up to 128GB of LPDDR5X over 16 channels.
N1 is aimed at thinner and cheaper laptops
Below N1X sits N1, which is described as the more restrained option in the lineup. This chip appears aimed at lower-cost laptops with tighter power budgets.
N1 is reported in two versions. The higher one uses 12 ARM cores in an 8P+4E layout and a 20 SM GPU equivalent to 2,560 CUDA cores, while the lower model drops to 10 ARM cores in a 7P+3E setup with a 16 SM GPU, or 2,048 CUDA cores.
The memory and power figures are also more modest. N1 supports LPDDR5X with 8GB to 64GB across 8 channels, and its TDP can be configured from 18W to 45W.
Clear separation between premium and mainstream designs
Storage expansion also appears to follow that split. N1X is said to support up to three M.2 slots, while N1 is limited to one M.2 slot.
That difference reinforces the idea that NVIDIA is building two distinct classes of laptop platform. N1X is being shaped for more premium and flexible systems, while N1 is set up for efficiency and affordability.
Earlier reports had already suggested that Lenovo may be preparing laptops based on this new NVIDIA chip family. What has changed now is the level of detail, with the leaked specifications giving a much clearer picture of how aggressive NVIDIA’s ARM push could be.
The full picture is still unofficial, and more details are expected when NVIDIA introduces the processors at Computex 2026. For now, the leaks point to a serious attempt to bring ARM laptops into a higher-performance tier, with N1X and N1 covering both premium and mainstream segments.
