Preorders for the Surface Laptop Ultra opened Oct. 7, alongside Microsoft's more expensive Surface RTX Spark Dev Box, as part of a broader Windows and Surface announcement. Both machines launched Oct. 16, alongside RTX Spark PCs from Asus, Dell, HP, Lenovo, and MSI, according to Tom's Hardware.
Pricing starts at $2,599 for the Surface Laptop Ultra and $5,999 for the Surface RTX Spark Dev Box. Both figures are US starting prices, so shoppers elsewhere should check their local Microsoft Store for regional pricing and availability.
Microsoft launched the Surface Laptop Ultra as part of Nvidia's new RTX Spark PC platform. The platform offers configurations with up to 6,144 Blackwell GPU cores, 20 Arm CPU cores, and 128GB of unified memory, alongside claims of up to one petaflop of AI performance.
The launch established the starting prices and Oct. 16 release date. Retail listings and independent reviews have since clarified the Laptop Ultra's configurations, display specifications, and performance.
Surface Laptop Ultra pre-order: price and release date
The Surface Laptop Ultra became available for preorder Oct. 7 and began shipping Oct. 16, starting at $2,599. The Surface RTX Spark Dev Box launched with a $5,999 starting price and the same release date.
The Laptop Ultra's entry-level configuration includes an 18-core RTX Spark N1X processor with 5,120 GPU cores, 24GB of unified memory, and 512GB of storage.
Higher configurations offer a 20-core processor with 6,144 GPU cores and up to 128GB of unified memory. The highest-end configuration, with 128GB of memory and 1TB of storage, is priced at $5,899.99, according to Tom's Hardware's review.
The laptop features a 15-inch display with a 3270 x 2180 resolution and a 120Hz refresh rate. Microsoft also offers Windows 11 Home on the 24GB configuration, while models with 32GB or more include Windows 11 Pro.
Buyers should check the exact configuration before ordering because the RTX Spark N1X name covers processors with different CPU and GPU core counts.
Surface Laptop Ultra vs Surface RTX Spark Dev Box: who each is built for
Microsoft positions the Laptop Ultra as a portable machine for creative professionals, developers, and users running demanding AI workloads.
The 4.5-pound laptop includes a bright HDR display and a magnetic USB-C charging system called Magnetic Connect.
At the launch event, Microsoft described the display as offering exceptionally high peak HDR brightness. Independent reviewers have since praised its brightness, though that doesn't prove Microsoft's broader claim that it has the brightest peak HDR display on any laptop.
The Surface RTX Spark Dev Box is a separate developer-focused desktop system starting at $5,999.
Its higher starting price doesn't automatically establish that it will outperform every Laptop Ultra configuration. Buyers should compare memory capacity, sustained performance, connectivity, and the intended workload before choosing between them.
The Dev Box is also distinct from Nvidia's DGX Spark and DGX Station for Windows.
Microsoft described the DGX Station platform as bringing powerful AI capabilities to desktop workstations, using Nvidia's GB300 Grace Blackwell Ultra Desktop Superchip and targeting models with up to a trillion parameters.
Those systems represent a different hardware category from the Surface Laptop Ultra and the RTX Spark Dev Box.
What Microsoft's AI benchmarks do not establish
Microsoft compared RTX Spark with Apple's M5 Pro chip at the launch event, citing up to 2.1 times faster time-to-first-token performance, 4.3 times faster image generation, and 6.2 times faster video generation.
Those are Microsoft's own comparison figures, not independent benchmark results.
In another demonstration, Microsoft showed DeepSeek V4 Flash running locally with 1.6-bit quantization and approximately 60GB of memory, according to Tom's Hardware.
That demonstration illustrates the platform's potential under controlled conditions. It doesn't mean the entry-level 24GB Laptop Ultra can run the same workload.
Independent testing is now available. Tom's Hardware found that RTX Spark performs well in local AI workloads but is less competitive in gaming and some conventional CPU tasks.
Its review also found that several of Microsoft's promised Windows AI features weren't ready for general availability when the hardware launched.
For developers running existing x86 software, Microsoft says its Prism emulator is optimized for RTX Spark PCs.
That optimization doesn't guarantee native-equivalent performance. Buyers should check whether their essential applications support Windows on Arm and whether independent testing has identified compatibility or performance limitations.
Software features tied to the launch
Windows ML is becoming a central runtime for deploying AI models across a PC's GPU, NPU, and CPU, while Llama.cpp support is intended to help developers run and experiment with local models.
Nvidia is also bringing its OpenShell technology to Windows, alongside Microsoft's newer security protections for AI agents.
Microsoft's Pavan Davuluri detailed Microsoft Execution Containers, OS-level sandboxes designed to control what information AI agents can access. Microsoft announced their move to general availability as part of the October event.
Davuluri also described a push toward hybrid intelligence, splitting AI tasks between local and cloud models to manage computing costs and improve efficiency.
Microsoft said Windows agents will need to identify their actions, while enterprise administrators will receive controls for managing agent behavior across devices.
HydraFusion, Microsoft's system for balancing local and cloud AI workloads, was scheduled to move from GitHub to Windows on Oct. 15, covering GitHub Copilot, the CLI, and VS Code.
The announcement also highlighted models including MAI Code 1.1 Flash and Nvidia's Nemotron.
Microsoft's Jacob Andreou demonstrated an updated Copilot that can access local files, run local models, and take approved actions, including preparing an email for the user's approval.
Andreou said those capabilities would arrive over the following months. Independent reviews published around the Oct. 16 hardware launch confirmed that several of the broader agentic Windows features were still unavailable in the stable release.
Gaming support follows a similar distinction between announced compatibility and measured performance.
At the launch event, Microsoft said hundreds of AAA and independent games would be playable on RTX Spark hardware, with Call of Duty support planned for 2027.
Microsoft also demonstrated Gears of War: E-Day running at 60 frames per second.
Those demonstrations don't establish consistent performance across supported titles. Tom's Hardware's subsequent testing found that RTX Spark's gaming capabilities are more limited than its local AI performance might suggest.
What to check before you order
Check Microsoft's current product listings for the exact memory, storage, processor configuration, and regional pricing before ordering either machine.
For the Laptop Ultra, the difference between the 18-core and 20-core RTX Spark configurations matters, particularly for buyers planning to run larger local AI models.
Developers should also confirm whether their existing tools run natively on Arm or depend on Prism emulation.
Independent reviews are now available, so buyers no longer need to rely exclusively on Microsoft's launch demonstrations. Those reviews indicate that the Surface Laptop Ultra is capable hardware for local AI, but its high price and the incomplete rollout of Windows' agentic features remain important considerations.
The Surface Laptop Ultra and RTX Spark Dev Box have moved beyond preorder status. The decision now is whether their available hardware capabilities justify the cost, rather than whether Microsoft's promised software ecosystem is already fully in place.
