Inside the Nvidia N1X: Leaked Specs, Delays, and What the Computex 2026 'New Era of PC' Teaser Really Means

Leaked Specifications: What the N1X Might Pack

While Nvidia has not officially confirmed any specifications, a consistent stream of leaks from benchmarks and supply-chain sources has painted a detailed picture of what the N1X might offer. The consensus points to a chip designed to deliver high-end gaming and AI performance from a single package. Key specifications, all unconfirmed, include the following.

CPU and Co-Design
The N1X is reported to feature a 20-core Arm-based CPU, arranged in two 10-core clusters that use Nvidia’s Grace architecture. This setup has previously been proven in the GB10 Superchip that powers the DGX Spark AI computer . The chip is a collaboration with MediaTek, which handles ARM IP integration and system-level design .

GPU
The integrated GPU is rumored to be based on Nvidia’s Blackwell architecture and configured with 48 Streaming Multiprocessors (SMs), totaling 6,144 CUDA cores. This is the exact core count of the desktop GeForce RTX 5070 . However, because it is an integrated GPU that shares power and thermal constraints with the CPU, real-world gaming performance is expected to be lower, with estimates placing it between a mobile RTX 5070 and an RTX 5070 Ti .

Memory and Manufacturing
Engineering samples and leaked motherboard images suggest the chip will support up to 128GB of LPDDR5X memory, pointing to a unified memory architecture similar to Apple's M-series chips . It is expected to be manufactured on an unspecified TSMC 3nm (N3) process node .

Power and Operating System
Leaks point to a flexible Thermal Design Power (TDP) envelope, configurable by manufacturers between 65W and 120W. This would allow the same silicon to be used in both thin-and-light ultrabooks and high-performance gaming laptops . The chip has also appeared in benchmarks running both Windows on Arm (WoA) and Linux AArch64, confirming the software ecosystem it will target .

The Long and Winding Road to Launch

The N1/N1X program has been known through leaks for years, and its path to market has been repeatedly pushed back. Early reports from 2025 suggested a launch in Q1 2026 . By January 2026, DigiTimes sources were still pointing to an initial debut that quarter, with more models in Q2 .

The most recent leaks, from April 2026, suggest the timeline has slipped further. Reports from Moore’s Law is Dead and Igor’s Lab indicate that while Nvidia will showcase the N1X at Computex in June, the first consumer devices may not ship until October 2026, with broader availability not expected until early 2027 . Dell's Alienware and Lenovo's Legion gaming brands are cited as the first OEM partners, with a Lenovo Legion 7 and its 245W charger already spotted in leaks .

Why the Delays? Silicon and Software Synchronization

The delays appear to stem from a two-pronged challenge: hardware redesigns and software readiness. Early engineering samples reportedly required "respins," or redesigns, which pushed back the validation and tape-out phases . Concurrently, Microsoft needed more time to ensure Windows on ARM was optimized for the new hardware, including its Prism emulator for x86 apps, driver support, and AI/ML APIs . This coordination between a new chip and a mature OS experience is crucial, as Microsoft does not want to repeat the underwhelming app compatibility of early Windows on Arm launches.

A New Battleground for PCs

If the leaked specifications prove accurate, the N1X would not be just another chip. It would become the most powerful integrated GPU ever shipped in a consumer laptop and the first credible Arm-based gaming platform for Windows . Its primary competitors are clearly defined: Qualcomm's Snapdragon X Elite/Plus series, which currently dominates the Windows on Arm space, and Apple's M4 Pro/Max chips, which lead on integrated graphics performance. By entering the laptop CPU market, Nvidia is also directly threatening the decades-long x86 duopoly of Intel and AMD in gaming laptops.

It is critical to note that every specification and timeline discussed beyond the May 29 teaser itself is based on leaks, shipping manifests, engineering sample benchmarks, and supply-chain rumors. Nvidia, Microsoft, and MediaTek have not officially confirmed any of these details. Jensen Huang's keynote on June 1st at Computex is expected to provide the first official clarity.
