128 GB of RAM and colossal power: the resounding return of Nvidia on laptop PC would be here

What is this mysterious Nvidia motherboard? A photo posted on Goofish, the Chinese “Bon Coin”, shows a new component that is unlike anything we currently know on the general public market.

What you see there is the Nvidia N1 SoC, the brand’s first real consumer processor since the Tegra silicon.

As with Apple with its M chips, the GPU is integrated into the SoC and shares the same memory as the CPU, excluding the dedicated VRAM and the PCIe bus between the two.

As you know, Nvidia no longer wants to be content with being the “graphics card supplier” for Intel or AMD. With this platform, Jensen Huang wants to offer his own “Apple Silicon” for PC. This mysterious Nvidia motherboard is not a simple evolution, you are undoubtedly looking at something completely new, a massive, welded processor, surrounded by a huge amount of unified RAM.

To succeed in this bet, Nvidia joined forces with MediaTek. The idea? Use the expertise of the Taiwanese giant for the processor part (CPU) under ARM architecture, and inject the architecture into it Blackwell for the graphic part. The result is undoubtedly the ultra-compact PCB you see there.

A monster hidden under the radiator

To fully understand what is hidden on this mysterious Nvidia motherboard, you have to look at the memory chips. There are eight modules of LPDDR5X signés SK hynixfor a total of 128 Go to RAM. This memory is not there by chance: it is unified, and shared between the processor and the graphics part, with a bandwidth of 273 Go/s.

The chip is the N1 SoC which has 20 ARM cores divided into two clusters: 10 Cortex-X925 performance cores and 10 Cortex-A725 efficiency cores. But the real shock is the integrated GPU.

With 6,144 CUDA Blackwell cores, the integrated GPU would aim, on paper, at the level of a GeForce RTX 5070, which is an order of magnitude, far from a measured promise. The first leaked Geekbench benches of an early sample drag on the level of an RTX 2050 Mobile, this which is explained by an unfinalized sample, but which invites caution.

Also look at the power stage, what we call the VRM. With an 8+6+2 phase power supply stage, we are clearly above what we see on a classic ultraportable. This betrays a high TDP: the N1 is not designed for fanless (like the MacBook Air) or ultra-thin 13-inch, but for muscular machines capable of absorbing its consumption.

The future of the laptop PC is at stake here

But then, what will this mysterious Nvidia motherboard be used for? The answer is in two letters: IA. By equipping its chip with 128 GB of unified RAM, Nvidia targets users who want to run complex language models (LLM) directly on their machine, without depending on the cloud. It’s a war machine for developers and creatives.

The other issue, it’s gaming on Windows on Arm. Until now, Qualcomm was a bit alone in the field, with sometimes capricious graphics drivers. With Nvidia at the helm, we can expect careful optimization.

According to leaks, the platform would be unveiled at Computex 2026, with machines expected from Dell and Lenovo, the two manufacturers would already be running prototypes. Nothing official from Nvidia at this stage.
