Following months of reports and a coordinated tease earlier this week, Microsoft has officially revealed the Surface Laptop Ultra, a new high-end laptop powered by Nvidia's long-rumored Arm-based RTX Spark chip. If this chip is coming out of nowhere for you, it's worth noting that it was known as the N1 and N1X in rumors leading up to its official reveal.

Microsoft says the laptop's powerful chip features Blackwell RTX cores, power-efficient cores, and up to 128GB of unified memory, supporting up to 1 petaflop of AI compute power, and that it emphasizes sustained performance per watt, allowing it to stay cool under intense workloads (specific core numbers for the RTX Spark featured in the Surface Laptop Ultra haven't been confirmed yet).

Other notable hardware specs include a 15-inch mini-LED PixelSense Ultra touchscreen display with up to 2,000-nit peak HDR brightness (262ppi). Additionally, the Surface Laptop Ultra features an expansive haptic touchpad that's larger than anything in the Surface line before, "all-day battery," and a weight of 4.5lbs (slightly heavier than the current 15-inch Surface Laptop). Ports include 3 USB-C ports, a USB-A port, an SD card slot, an HDMI port, and a 3.5mm headphone jack (it's unclear how fast its USB ports are). Colors include a black-like Nightfall and a silver-looking Platinum. Microsoft hasn't revealed the Surface Laptop Ultra's full technical specs yet, but this story will be updated as more information becomes available.

The tech giant says that the Surface Laptop Ultra's RTX Spark chip has been optimized for Windows with developer and creator workloads in mind, and lists several key apps that have been optimized for the chip through Nvidia's and Microsoft's ongoing partnership with app developers, including Adobe's suite, Affinity, Claude Code, GitHub Copilot, the Xbox app, the Epic App, and more.

In its press release, Microsoft emphasizes that it designed the Surface Laptop Ultra "from the inside out," stating that "Mechanical, electrical, thermal, acoustic, materials, industrial design, and software engineers" worked on the high-end laptop from day one to create a laptop that embodies the following statement: "Nothing wasted. Everything intentional."

The Surface Laptop Ultra looks a lot like the current Surface Laptop

More laptops that feature Nvidia's RTX Spark chip are definitely on the way

The Surface Laptop Ultra looks very similar to the recently revealed 15-inch Surface Laptop for business (8th-generation), including its squared-off sides and minimized bezels. It's worth noting that Microsoft used Nvidia's Arm-powered Tegra chip for its original Surface RT tablet back in 2012, before eventually partnering more closely with Qualcomm on its Surface-related Arm efforts several years later, a partnership that continues today.

Alongside the Surface Laptop Ultra, companies like Asus, Dell, HP, and Lenovo will launch products featuring Nvidia's new RTX Spark chip.

Microsoft says the Surface Laptop Ultra is scheduled to release this coming fall, and states that pricing will be available closer to its release. The company has significantly adjusted its strategy for Surface products over the last few years, including killing off the Surface Book, the Surface Hub touchscreen, the Surface Duo, and even the Surface Laptop Studio.

Windows on Arm has improved notably over the past couple of years, thanks to the foundational work by Microsoft and Qualcomm on the Snapdragon X series of chips. With the Surface Laptop Ultra, it's clear that Microsoft is confident in what Nvidia is bringing to the ecosystem, and an additional chipmaker entering the fray will almost certainly push adoption and compatibility of Windows on Arm further than before.
