NVIDIA's leaked N1x chip for ARM laptops has as many CUDA cores as an RTX 5070 — but don't expect the same performance

Nvidia CEO Jensen Huang holds a Blackwell GeForce RTX 50 Series GPU (L) and a RTX 5000 laptop as he delivers a keynote address at the Consumer Electronics Show (CES) in Las Vegas, Nevada on January 6, 2025.

It's no longer much of a secret that NVIDIA is developing its own System-on-Chips (SoC) — currently named "N1" and "N1x" — for use in laptops and, potentially, desktop PCs.

Rumors began in 2023 that NVIDIA was weighing its options regarding an ARM SoC for Windows PCs, and only more recently have leaks begun to appear.
