Nvidia's RTX Spark N1X arrives in Windows laptops from six makers

Nvidia's RTX Spark N1X processor is here, and The Verge's reviewers have spent a week testing a small fortune's worth of laptops built around the new chip. It's Nvidia's bid to become a serious player in Windows PC silicon, a market that Apple, Intel, AMD and Qualcomm have largely divided among themselves.

RTX Spark is an Arm-based system-on-a-chip (SoC) for laptops and small desktop computers. Nvidia positions it as a high-performing rival to the best chips from those four competitors. The design stacks up plenty of CPU cores, Nvidia RTX Blackwell graphics, and enough power and unified memory to run sizable AI models locally — without a cloud connection.

That last point is the context that matters. Running large models on-device has mostly been Apple's territory, with Qualcomm's Snapdragon X chips chasing it on the Windows side. Nvidia entering the race changes the math for anyone who wants local AI horsepower in a laptop.

Which laptops carry the new chip?

Six different manufacturers are shipping Windows laptops with RTX Spark inside. The Verge's team has collectively tested four of them so far, including:

• Microsoft Surface Laptop Ultra — the flagship placement, configured with a staggering 128GB of unified memory, fully reviewed by Tom Warren
• Asus ProArt P16 — a 64GB version tested by Sean Hollister
• HP OmniBook Ultra
• Lenovo Yoga 9n

The Surface Laptop Ultra configuration is the headline spec. 128GB of unified memory in a laptop is the kind of number that makes local AI workloads practical rather than theoretical, because large models are memory-hungry in a way most laptop hardware hasn't accommodated.

Why does an Nvidia PC chip matter now?

Nvidia dominates the market for discrete AI accelerators in data centers, but it has been absent from the mainstream laptop SoC business. RTX Spark changes that by putting Blackwell graphics and Arm CPU cores on a single chip with a shared memory pool — the same architectural bet Apple made with its M-series and Qualcomm made with Snapdragon X.

Unified memory is the mechanism worth understanding. Instead of splitting RAM between the CPU and GPU, both draw from one pool. That lets a laptop load AI models that would otherwise exceed a GPU's dedicated memory. For developers and researchers who want to run models locally, that's the difference between a demo machine and a daily driver.

The competitive stakes are straightforward. If Nvidia can pair its graphics and AI software stack with competitive battery life and app compatibility on Windows, it pressures Intel, AMD and Qualcomm in a segment where Arm-based Windows machines are still fighting for credibility.

What we know about the laptops so far

The Verge's impressions cover build variety rather than a single reference design. Asus put the chip in the ProArt P16, a creator-focused machine. HP and Lenovo used the OmniBook Ultra and Yoga 9n respectively, mainstream premium lines. Microsoft's Surface Laptop Ultra sits at the top with the 128GB memory option.

That spread matters because a new SoC succeeds or fails on how many PC makers bet on it. Six manufacturers at launch is a broad base for a first-generation chip, and four tested units suggest the hardware is shipping in volume, not just announced.

The takeaway: RTX Spark is real, it's in shipping laptops from six brands, and reviewers have had extended hands-on time with four of them.

What's next?

The full picture of performance, battery life and app compatibility will come from The Verge's complete impressions, which cover the week the team has spent with the Asus, HP and Lenovo machines. What's already clear is the direction: Nvidia wants the same dominance it has in AI data-center hardware on your desk, and RTX Spark is its opening move in laptops. How well first-generation Arm compatibility holds up under daily use will decide whether that move sticks.
