During yesterday's Q&A with Intel and NVIDIA CEOs, NVIDIA CEO Jensen Huang confirmed that the current GB10 "Grace Blackwell" Superchip is the base design of the upcoming N1 laptop processor. "We also have a new Arm product that's called N1. And that product is—that processor is going to go into the DGX Spark and many other versions of products like that. And so we're super excited about the Arm road map, and this doesn't affect any of that," said Jensen Huang. This means that the GB10 Superchip is the blueprint for the design of N1, and we can already create a rough performance tier based on the previous information about the GB10.

At Hot Chips 2025 , NVIDIA gave more details about GB10. The chip pairs a MediaTek-sourced Arm CPU die with a Blackwell GPU die in a 2.5D package built on TSMC's 3 nm process. The CPU side implements 20 Arm v9.2 cores split into two clusters of ten, each cluster backed by a 16 MB shared L3 (32 MB total) while each core retains private L2 storage. The memory subsystem is a unified LPDDR5X-9400 fabric on a 256-bit bus, supporting up to 128 GB and delivering roughly 301 GB/s of raw bandwidth to the package. For consumer laptops, we need to see if this memory capacity remains an option. High-speed I/O is concentrated on the CPU die, while NVMe storage and peripherals ride PCIe 5.0 lanes there. The package is rated at approximately 140 W TDP and exposes multi-display outputs (DisplayPort alt-mode plus HDMI 2.1a options) alongside security and virtualization features intended for professional workloads.
