Nvidia’s RTX Spark N1X has arrived in laptops aimed at developers, creators and people who want to run local AI models. A week of testing across five laptops suggests the chip can make Windows on Arm feel capable for everyday work and gaming, though the experience varies by software and comes at a high price.
Everyday Windows use is mostly smooth
Windows on Arm has improved as more apps have gained native versions and Microsoft’s Prism emulation layer has made many x86 programs usable. Testers reported that common work and personal apps generally ran without requiring them to think about which processor architecture an app was built for.
Adobe’s Photoshop and Premiere have native Arm versions. Lightroom Classic remains an x86 app, but one tester said it worked without noticeable problems. Another used Signal, Discord, Audacity, CapCut, Evernote, Irfanview, Slack and ScreenToGif as daily apps, with nothing failing outright during the test week.
There were occasional annoyances. Some apps took longer than expected to open, Evernote notes temporarily disappeared after switching away, and apps did not always follow the system’s dark mode preference. A force refresh fixed the Evernote issue, but these moments show that the experience is not entirely seamless.
Specialized software available only for x86 Windows remains a potential obstacle. Gaming also presents more compatibility uncertainty than ordinary productivity, especially for people who want to run any title without checking whether it works.
Gaming benefits from Nvidia graphics, with limits
The N1X laptops pair a 20-core CPU with 6,144 GPU CUDA cores. Nvidia’s graphics hardware can help games run through emulation even though there are still few native Arm games. One tester found that medium graphics settings, 1440p and DLSS performance mode delivered a stable 60fps in most of the games tested, though results depended on the title.
On a 15-inch display, medium settings were considered acceptable by a tester accustomed to high-end desktop gaming. Black Myth: Wukong averaged 70fps at native resolution, 3270 x 2180, with medium settings and DLSS performance mode. Cyberpunk 2077 averaged 66fps under the same settings, while Forza Horizon 6 averaged 57fps.
Other games showed the range of outcomes. Returnal reached a smooth 60fps at 1440p with high settings. Expedition 33 and Jedi Survivor also ran smoothly with DLSS performance upscaling and reduced settings, while Shadow of the Tomb Raider ran at native 1800p with its highest settings.
The CPU can be the constraint. Helldivers 2 could not reliably maintain 60fps in its most demanding missions, even with DLSS-upscaled 1080p. Star Wars Zero Company stayed between 37fps and 39fps in battle regardless of graphics settings or resolution, suggesting that lowering visual quality could not solve that game’s bottleneck.
Compatibility quirks appeared in older and simpler games, too: Max Payne 2 sometimes dropped to 50fps, and UFO 50 had a few hitches. A Titanfall 2 VR mod initially worked, but became less stable after a few minutes. The Steam Frame wireless adapter driver and Steam’s streaming audio solution would not install, leaving sound on the laptop rather than the headset.
Power comes with a premium price
The RTX Spark N1X is intended for laptops and small desktop computers, with Nvidia RTX Blackwell graphics and unified memory suited to running sizable local AI models. The laptops tested included configurations with 32GB, 64GB and 128GB of memory.
These are high-end machines, and the prices reflect that. The HP OmniBook Ultra tested cost $3,199.99, while the Asus ProArt P16 reached $6,999.99. Lower-cost configurations with an 18-core chip and 5,120 CUDA cores start at $2,599.99 for a Surface Laptop Ultra or a smaller Asus ProArt P14 with 24GB of RAM.
For gaming, these systems are not a substitute for a dedicated gaming laptop. Some titles require lower settings or resolution, and CPU-heavy games can struggle even when the graphics options are reduced. The appeal is broader: a high-end Windows laptop that can handle creative work, many games and local AI in one device.
A promising platform still has trade-offs
The week of testing points to a more practical Windows on Arm experience than the platform had a few years ago. Everyday apps were largely reliable across the tested laptops, and Nvidia’s graphics performance gives the category a stronger case for gaming and creative workloads.
Buyers still need to consider their own software and games. An x86-only specialist app, a CPU-bound game or a peripheral whose driver will not install can change the experience. With prices starting in the thousands of dollars, RTX Spark looks best suited to people who can use its mix of graphics, memory and local AI capabilities, rather than shoppers seeking an affordable general-purpose laptop.
