The most consequential laptop chip announcement in years is happening tomorrow. Microsoft and NVIDIA both teased “a new era of PC” this week, and now — just hours before the Computex 2026 keynote — detailed specifications for NVIDIA’s N1 and N1X processors have leaked via VideoCardz, citing internal NVIDIA documents. Jensen Huang will officially announce the N1 and N1X at Computex on June 1, 2026 at 11 AM Taipei time.
NVIDIA is entering the laptop processor market for the first time since 2011. And it is not entering quietly.

Full Leaked Specs: N1X vs N1
According to the leak, the flagship N1X configuration features a 10+10 core CPU setup based on ARM’s Cortex-X925 and Cortex-A725 designs, paired with a 48 SM Blackwell GPU packing 6,144 CUDA cores.
| N1X (Full) | N1X (Variant) | N1 (High) | N1 (Base) | |
|---|---|---|---|---|
| CPU Cores | 20 (10+10) | 18 (9+9) | 12 (8+4) | 10 (7+3) |
| Core Config | Cortex-X925 + A725 | Cortex-X925 + A725 | Cortex-X925 + A720 | Cortex-X925 + A720 |
| GPU | 48 SM / 6,144 CUDA | 40 SM / 5,120 CUDA | 20 SM / 2,560 CUDA | 16 SM / 2,048 CUDA |
| Architecture | Blackwell | Blackwell | Blackwell | Blackwell |
| Max Memory | 128GB LPDDR5X | 128GB LPDDR5X | 64GB LPDDR5X | 32GB LPDDR5X |
| TDP | 45W–80W | 45W–80W | 18W–45W | 18W–45W |
| M.2 Slots | Up to 3 | Up to 3 | Up to 2 | 1 |
| PCIe | 12x Gen 5 + 5x Gen 4 | 12x Gen 5 + 5x Gen 4 | 8x Gen 5 + 3x Gen 4 | 8x Gen 5 + 3x Gen 4 |
The N1X will reportedly start at 16GB LPDDR5X configs with the platform supporting up to 128GB across 16 channels at an estimated 8,533 MT/s — which would make it faster than AMD’s Strix Halo memory configuration.
The DGX Spark Connection — Supercomputer Power in a Laptop
Based on the leaked specifications, NVIDIA’s top N1X chip appears to be the same processor as the GB10 chip inside NVIDIA’s DGX Spark. The DGX Spark is the $3,999 AMD Ryzen AI Halo competitor that NVIDIA positions as a desktop AI supercomputer.
The laptop variant of the N1X features 20 ARM CPU cores: 10 Cortex-X925 performance cores and 10 Cortex-A725 efficiency cores. By comparison, the N1X in the DGX Spark supercomputer uses custom NVIDIA Grace CPU cores. The chip is configured for a 45–80W TDP in laptops, down from 140W in the DGX Spark.
The full-fat N1X’s 6,144 CUDA core count is the same as the desktop RTX 5070. Getting RTX 5070-class graphics inside a laptop SoC — with unified memory up to 128GB — is a step-change from anything Qualcomm’s Snapdragon X Elite currently offers.
Who Is Building N1X Laptops?
ASUS ProArt, Microsoft Surface, Dell XPS, and multiple Lenovo models are confirmed or teased to use these chips.
The chip is reportedly a 20-core ARM SoC co-designed by NVIDIA and MediaTek, with 10 high-performance Cortex-X925 cores alongside 10 efficient Cortex-A725 cores. The MediaTek co-design relationship is significant — it gives NVIDIA the manufacturing and mobile silicon expertise that an x86-dominant GPU company lacks in-house, and it is the same partnership that underpins the GeForce NOW mobile ecosystem.
Lenovo’s Legion 7 with N1X will require a 245W power adapter, suggesting high-performance gaming variants are on the roadmap. A Legion gaming laptop running Blackwell GPU architecture at 80W TDP with 128GB unified memory is a genuinely different product category from anything currently available.
Why This Changes the Windows on ARM Story
Microsoft has been working hard to get Windows on ARM off the ground, and until now it has had only Qualcomm’s support. With NVIDIA entering the scene, the pair could push the Windows on ARM ecosystem into territories we could only have dreamed of before.
Qualcomm’s Snapdragon X Elite was the first credible Windows on ARM chip — but its GPU capability is limited compared to what an NVIDIA-designed Blackwell GPU can deliver. For developers, content creators, and AI workload users who need GPU headroom, the Snapdragon X Elite simply has not been enough. Windows on ARM gaming support has improved dramatically over the past year, making these NVIDIA-powered laptops potentially viable for both productivity and gaming.
For local AI inference use cases — the same workloads where RTX 5060 Ti 16GB and AMD Ryzen AI Halo have been the go-to options — a laptop with 128GB unified LPDDR5X and 6,144 Blackwell CUDA cores running at 45–80W would be the most powerful portable AI inference machine ever offered at laptop form factor and pricing.
When Can You Buy One?
More details will be available when NVIDIA officially unveils these processors at Computex 2026. A Computex 2026 first N1X-based laptops showcase is expected, but consumer availability could slip into late 2026 or 2027.
The full official reveal is hours away. Read the official NVIDIA GeForce news at nvidia.com/en-us/geforce/news and follow Computex 2026 live updates for Jensen Huang’s keynote.
The Bottom Line
NVIDIA has been teasing “a new era of PC” — and this seems to be it. ARM-based laptops with high-performance NVIDIA Blackwell graphics challenge the norms of the laptop world entirely. RTX 5070-class GPU performance, up to 128GB unified memory, Blackwell architecture, a 45–80W power envelope, and confirmed devices from ASUS, Microsoft, Dell, and Lenovo — the N1X is the most significant laptop chip announcement since Apple’s M1 in 2020.
Stay tuned to TechnoSports for live Computex 2026 coverage, NVIDIA N1X official specs, laptop pricing, and India availability updates.
