After setting up Microsoft's Surface Laptop Ultra, the first reaction is not awe at the display or the aluminum chassis. It is a practical question: what would a normal person actually do with a $5,900 Windows laptop? The Surface Laptop Ultra is not a regular Windows machine. Microsoft teamed up with Nvidia to build a high-end laptop around Nvidia's new Arm-based RTX Spark chips, a combination meant to showcase what Windows on Arm can do when it is paired with a serious GPU and a large pool of unified memory.

The promise is compelling. The RTX Spark can run demanding AI models locally, handle creative apps, and play many of the latest games without relying on a cloud service. But the reality of local AI is much messier. Getting the most out of the Surface Laptop Ultra, especially the top configuration, requires coding experience or the patience to experiment with models and AI agents until something works. For developers and power users, that may be exactly the point. For everyone else, this is a very expensive glimpse of a future that has not fully arrived.

The Surface Laptop Ultra looks and feels like Microsoft's most serious attempt yet to build a Windows rival to Apple's professional laptops. The all-aluminum design, the high-end finish, the large haptic trackpad, and even the nightfall color all invite comparisons to a space-black MacBook Pro. The hardware is not merely derivative, though. Microsoft has made several choices that give the machine its own identity.

The 15-inch mini-LED display is the clearest example. It can reach up to 2,000 nits of peak HDR brightness at 262 pixels per inch, which Microsoft says makes it the brightest display it has ever shipped on a Surface Laptop. The MacBook Pro peaks at 1,600 nits. The Surface also uses a 3:2 touchscreen, a taller shape that is well suited to writing code, reading documents, and editing photos. The port selection is similarly practical: three USB-C ports, USB-A, HDMI 2.1b, an SD card reader, and a headphone jack.

The standout addition is Magnetic Connect. It works like the old Surface Connect, but through the USB-C port on the right-hand side. Bring the connector close and it snaps into place. When the laptop is not charging, that port behaves like any other USB-C port. The magnetic end can also be reversed and attached to the power brick, leaving a regular USB-C connector at the other end of the cable for charging other devices. It is a small design decision, but one that makes the laptop feel more thoughtful in daily use.

The large haptic trackpad is another welcome upgrade. It provides feedback for clicks, drags, and window alignment throughout Windows 11, and some apps such as PowerPoint can trigger tactile responses when objects or images are dragged into place. The effect is subtle, but it makes the interface feel more physical. More apps should support it. The 1080p front camera is fine for video calls and supports Windows Hello face authentication and Windows Studio Effects such as automatic framing, eye contact, and background blur.

Not all of the hardware experience is polished. The review unit sometimes reported a battery level of 97 percent immediately after being unplugged at 100 percent, then returned to 100 percent when plugged in and dropped again when unplugged. Microsoft says this is intentional. When the battery is full, the device pauses charging rather than constantly topping off, and resumes only once the level drops to 95 percent. That reduces wear over time. While plugged in, the indicator shows 100 percent to indicate a full charge; when unplugged, it shows the exact level right away.

There were other bugs. The display sometimes felt slightly laggy or showed noticeable ghosting, with a small trail when windows were moved rapidly. Changing the power setting from the default best power efficiency mode to best performance seemed to fix most of the laggy feeling, and backlight ghosting became less noticeable over time. The built-in speakers also produced loud pops and bangs that sounded like firecrackers. Rebooting solved the issue, but it happened more than once. Rebooting itself was surprisingly slow, which seems like something Microsoft could fix with an update.

Local AI models and agents

The RTX Spark chip is the reason this laptop exists. The reviewed model has a 20-core CPU codesigned by Nvidia and MediaTek, a 6,144-CUDA-core GPU roughly comparable to a mobile RTX 5060, 128GB of unified memory, and a 1TB Gen 5 SSD. That is a workstation-class memory configuration for a laptop, and it is meant to make local AI models and agents practical without sending data to the cloud.

Out of the box, Microsoft prompts Surface Laptop Ultra owners to choose an AI agent. The options include Hermes, OpenClaw, and Perplexity. Hermes and OpenClaw were tested with the Qwen3.8-27B model, one of the more powerful local models available. Because it uses the full power of the machine, even basic queries can spin up the fans at full throttle and push the GPU to 100 percent. A simple task such as resizing and converting photos from PNG to JPG took minutes, while the laptop grew hot and the fans buzzed. A utility could have done the same job in seconds.

Using such a large model for a basic task may have been a mistake, but that is part of the problem. Without testing every local AI model, it is hard to know which one to choose for each job. OpenClaw was asked to build a smart home dashboard and spent 30 minutes spinning up the fans and calling various tools before producing only an error. The experience feels like a beta, not a finished feature.

There are compelling use cases. Local AI can be useful for leaving an agent running overnight to build something, or for processing large datasets that would otherwise cost a lot in cloud tokens. It also offers privacy advantages. Hermes was given audio and video files and created a local llama.cpp server for audio transcription. It took some fiddling, but it could save the cost of a transcription app or a cloud service. The problem is that these agents are far from user-friendly, and Microsoft and Nvidia have not yet provided a first-party local AI interface that simplifies the work.

The base model's 24GB of unified memory will also limit how many local AI models can be used. The reviewed 128GB configuration has far more headroom, but it also costs far more. This is a laptop for people who already understand model sizes, quantization, CUDA, and agent workflows. It is not yet a machine for someone who simply wants AI features to appear automatically in Windows.

Gaming and creative tasks

The Surface Laptop Ultra is not an official gaming laptop, but it can run far more of the latest games than a MacBook Pro. Windows on Arm has traditionally been a nervous proposition for gaming because Qualcomm's Snapdragon X chips have weak GPUs. The RTX Spark changes that equation by pairing an Arm CPU with a stronger Nvidia GPU. Most games run well for a laptop that is not the size of a gaming machine.

At native resolution, with medium settings and DLSS performance mode, Black Myth: Wukong averaged 70fps. Cyberpunk 2077 averaged 66fps, and Forza Horizon 6 averaged 57fps. Most games need medium settings and DLSS performance or balanced mode to reach around 60fps. Gears of War: E-Day averaged 40fps on medium and only reached 48fps on low. Doom: The Dark Ages needed low settings and DLSS performance to hit 60fps. For a 15-inch display, medium settings can look closer to console settings, and the difference in texture quality is not always obvious.

Compatibility is good for most titles, but emulation issues remain. Horizon Zero Dawn Remastered was limited to 30fps at 1440p regardless of whether low or medium settings were used, likely because the game is CPU-heavy. A native Arm port would probably help. Native Arm games are still rare, but Marvel Rivals averaged 64fps with medium settings and DLSS performance, and 75fps on low settings. Arm ports are likely to appear mainly for games with heavy CPU activity or anti-cheat engines that are difficult to emulate. Games such as Arc Raiders, Counter-Strike 2, Dota 2, and Fortnite work out of the box, while Nvidia and Microsoft are working with publishers to support titles such as Battlefield, Call of Duty, Valorant, and League of Legends.

For creative work, the Surface Laptop Ultra is capable but not dominant. A 4K video export in Premiere Pro took 2 minutes and 18 seconds, around a minute behind a top-of-the-line MacBook Pro, around 30 seconds behind an M5 Pro system, and faster than a base M5 chip. The test had to be run through Premiere Pro's own export tool because a beta Arm version of Media Encoder had a bug. CPU performance is where the Surface falls furthest behind Apple's M5 chips. Single-core and multi-threaded tests in Geekbench and Cinebench show the MediaTek CPU is weaker than an M5 Max or even an M6 Mac Mini. Some GPU tests also favor Apple, and Photoshop, Premiere Pro, and DaVinci Resolve benchmarks are noticeably behind the M5 Max.

Battery life depends heavily on workload. With local AI models, a mix of apps, and gaming, the Surface Laptop Ultra lasts around seven hours. With lighter work, it averages 10 hours or more. That is usable for a high-performance laptop, but it is not a breakthrough in efficiency.

The Surface Laptop Ultra does not offer a clear performance advantage over the MacBook Pro outside some AI workloads such as image generation and native CUDA compute. It is not transformative for Windows the way the M1 chips were for macOS, largely because Qualcomm already moved Windows on Arm forward with the Snapdragon X series. The machine is difficult to recommend unless a buyer specifically wants to run local AI models, write code, or experiment with AI agents. More affordable laptops can handle everyday productivity, creative work, and light gaming without the price premium.

Microsoft has come closer than ever to building a Windows alternative to the MacBook Pro. The hardware looks and feels great, and Nvidia's GPU brings CUDA support and decent gaming to a high-end laptop design. But the Surface Laptop Ultra's biggest selling point is also its biggest question mark. Local AI still feels like a work in progress, and the laptop's appeal is narrow: it is a workstation for people who already know why they need CUDA and on-device models, not a general-purpose replacement for a premium MacBook Pro.
