N1X: The High-End Option
The top-tier N1X reportedly shares its core design with the GB10 processor inside Nvidia's DGX Spark desktop AI supercomputer.
It packs a 20-core CPU with ten Cortex-X925 performance cores and ten Cortex-A725 efficiency cores, paired with a Blackwell 2.0 GPU featuring 48 Streaming Multiprocessors, equating to 6,144 CUDA cores.
A slightly trimmed N1X variant drops to 18 CPU cores (nine performance, nine efficiency) and a 40-SM GPU with 5,120 CUDA cores.
Both N1X chips are designed to run at 45W to 80W for the entire chip package.

N1: For Thinner and More Affordable Devices
The standard N1 lineup includes two variants.
The higher-end one pairs eight Cortex-X925 performance cores and four Cortex-A725 efficiency cores with a 20-SM GPU delivering 2,560 CUDA cores.
The entry-level option steps down to a 10-core CPU (seven performance, three efficiency) and a 16-SM GPU with 2,048 CUDA cores.

Memory and Storage Differences
The N1X supports up to 128GB of LPDDR5X memory across a 16-channel interface, while the standard N1 caps at 64GB with an 8-channel setup.
For storage, N1X supports up to three M. 2 SSDs, while the N1 tops out at two.
Long-Term Ambitions
According to VideoCardz, at least one of the leaked slides is dated 2024, suggesting Nvidia may have been working on these chips for two years or more.
