Surface Laptop Ultra: Microsoft breaks with Intel and AMD and debuts the NVIDIA RTX Spark chip

Microsoft announced at Computex 2026 the Surface Laptop Ultra, its most powerful laptop and the first in its history to forgo Intel and AMD in favor of NVIDIA silicon. The break is hard to measure: for the first time, a Surface can stand on equal ground with a MacBook Pro in heavy computing, aimed at AI developers and creators. The company presents it as the machine for 'world makers,' and although for now, it's more of a preview than a finalized launch, it's enough to change the conversation about what a Windows laptop can be.

What is the Surface Laptop Ultra and why it matters

For years, the premium Surfaces were a step below the latest hardware: neither the Surface Book nor the Laptop Studio reached the top tier. The Surface Laptop Ultra breaks that mold because it is built on the NVIDIA RTX Spark platform from end to end, not just a GPU slapped on at the end: it is the first Microsoft device designed 'from the silicon out' around an NVIDIA chip.

The move has symbolic and technical weight. For decades, PC processors running Windows were Intel and AMD's territory; now, NVIDIA steps in with an architecture tailored for the local AI wave, and Microsoft accompanies it with operating system-level changes to optimize it. The positioning is direct: Microsoft’s answer to the MacBook Pro for those who develop and create.

Design, ports, and touchpad

It measures less than 18 mm thick and weighs under 4.5 pounds (2 kg), available in two finishes: Platinum and a new Nightfall (black) that steals all the photos. An honest nuance pointed out by the press: 4.5 pounds isn’t record-light, but a reasonable trade-off to pack this hardware into a slim body.

In a world of laptops that force you to carry dongles, it features a complete set of ports in its chassis: HDMI, USB-C, USB-A, a full-size SD card reader, and a headphone jack, just what creators need in the field. The touchpad also grows: haptic and more than 30% larger than the previous one, the largest ever placed in a Surface.

The NVIDIA leap: RTX Spark and 1 petaflop

Here lies the heart of the announcement. The RTX Spark chip combines a CPU with up to 20 cores and a Blackwell GPU with 6,144 CUDA cores, linked by NVLink C2C, and adds up to 128 GB of LPDDR5X unified memory with up to 300 GB/s of bandwidth. Together they deliver up to 1 petaflop of AI computing, with a GPU on par with an RTX 5070 and capable of running models up to 120 billion parameters locally.

The unified memory defines this machine as 'Ultra': instead of dividing system RAM and video memory into fixed compartments, it dynamically allocates that 128 GB pool between CPU and GPU, depending on task demand. It's the same principle used by Apple and Qualcomm, now joined by NVIDIA. The RTX Spark is a new platform worth an article of its own; that the Surface Laptop Ultra is among the first devices to debut it is already news.

This power demands equally effective cooling. Microsoft redesigned the thermal system with dual ventilation and up to 2.5 times the dissipation capacity of the 15-inch 7th-gen Surface Laptop, aiming at sustained performance: enduring long renders or compilations without the aggressive throttling seen in powerful laptops of yore.

Display: the brightest Microsoft has made

It features a 15-inch mini-LED PixelSense Ultra panel, 2880 x 1920 resolution, 262 ppi, and a 3:2 aspect ratio, taller than the regular 16:9 and better for work. It reaches up to 2,000 nits peak brightness in HDR, the brightest display Microsoft has installed in a Surface. This isn't just a spec sheet number: it's designed for those making critical color and exposure decisions, where brightness and color accuracy translate into trusting what you see when editing.

Local AI: the end of "token anxiety"

Microsoft has focused on running AI models on the device itself. The idea, in their words, is to cure 'token anxiety': experimenting without watching the cloud cost counter, with lower latency and more privacy since the data doesn't leave the device. When edge intelligence is needed, it scales to the cloud; otherwise, everything runs locally.

This connects with the wave of AI agents, assistants that perform actions for you like debugging code. For this era, Microsoft adds containment primitives: a sandboxing system that limits the data each agent accesses and prevents them from touching the system's core. Practically, apps can use the GPU for noise reduction, intelligent masking, video upscaling, and code autocomplete, all on-device.

Repairability: the angle almost no one sees

A detail nearly unnoticed in coverage merits attention. The Surface Laptop Ultra is designed for repairability: user-replaceable SSD, internal signaling to guide repairs, published service guides, and replacement parts available via Microsoft Store and iFixit.

The detail carries more weight than it seems. In an era where memory is soldered on, and unified architecture pushes to integrate everything into the chip, keeping storage serviceable goes against the industry. The concrete benefit: a device that grows with the user, less friction in corporate environments, and longer lifespan. That NVIDIA and the unified memory haven’t sacrificed the replaceable SSD is a design decision to value.

What Microsoft aims for and who they stand against

A clarification is in order before any comparison: all figures Microsoft presented are for the top tier (the famous 'up to'). The 20 cores, the 6,144 CUDA, and the 128 GB are the maximum announced configuration, not a specific one. The company hasn’t yet detailed what the base model or its price will be, so any comparison is made against that ceiling, not an entry-level version that doesn't exist on paper yet.

With that caveat, the natural competitor to the Surface Laptop Ultra in its maximum configuration is the MacBook Pro with M5 Max chip: both occupy the same portable workstation territory, with 128 GB of unified memory and a top-tier GPU oriented towards local AI and heavy creative work. Where Apple puts 40 GPU cores and 614 GB/s bandwidth, NVIDIA responds with 6,144 CUDA cores and full CUDA compatibility, a huge advantage for those developing within that ecosystem. The M5 Pro, with its 64 GB cap, plays a step lower.

The other front is internal to Windows: Qualcomm's Snapdragon X2 Elite Extreme, currently the dominant ARM chip on the platform. Here, the fight isn’t so much about raw power (NVIDIA aims higher, at the segment with dedicated GPU) but about where Windows on ARM is headed. The difference is that the Ultra adds a Blackwell GPU that no Snapdragon offers, in exchange for a consumption and price that promise to be quite higher.

The uncomfortable conclusion is the same for all three: on paper, the Surface Laptop Ultra sits at the big league table, but almost everything is 'up to,' with no confirmed price or independent benchmarks, while the M5 Max is already out in the market and tested. The promise is enormous; the verification, pending.

The fine print: what the announcement doesn't shout

Behind the '1 petaflop' headline lie three asterisks.

It’s Windows on ARM. It doesn’t run native x86: it uses the Prism emulation layer for software not yet ported to ARM, historically the platform’s Achilles heel. It has improved considerably (native anti-cheat and games like Valorant and League of Legends are coming, with Prism finetuned for the RTX Spark), but it’s worth keeping in mind if your workflow depends on older or very specific programs.

There’s no price. Microsoft dodged the most obvious question, stating they will talk about prices closer to the launch, due to volatility in RAM and NAND markets. The reading from specialized press is unanimous: it will position at the very high end, particularly the 128 GB model.

Copilot+ remains vague. It’s unclear whether it combines a dedicated NPU with the RTX GPU or relies solely on the GPU for AI functions. Microsoft presents it as Copilot+ PC but left loose ends. And it’s a pre-release product, even subject to FCC approval before going on sale.

Conclusion: Revolution or expensive preview?

It's the most ambitious Windows hardware announcement in years. For the first time, Microsoft has a laptop that, on paper, stands toe-to-toe with Apple's best for AI and heavy creative work, and the break with Intel and AMD points to where Windows is heading. The bet on repairability, where everyone else solders and seals, adds value.

But today, it’s a promise with caveats: ARM emulation has to withstand the real world, the price threatens to be exorbitant, and 'all-day' battery life is still marketing with an asterisk. The test comes when the device is out, with independent benchmarks and a full announced range, later this year. If it delivers even half of what it shows, the conversation about powerful laptops will no longer be Apple's alone. If not, it will be the most impactful preview that we couldn’t buy.
