Microsoft Surface Laptop Ultra is the first laptop built around NVIDIA's RTX Spark chip — a $2,599 AI workstation that runs huge AI models locally instead of in the cloud. Verdict: a serious MacBook Pro challenger for developers and creators, but the 24GB base model is not the 128GB headline machine — buy the memory, not the marketing.
Microsoft opened pre-orders on October 7 at a San Francisco event where Satya Nadella and NVIDIA's Jensen Huang pitched it as the machine that moves AI off the cloud and onto the laptop. Shipping begins October 16. It is the first retail laptop on NVIDIA's Arm-based RTX Spark superchip, pairing a Grace CPU with a Blackwell RTX GPU and up to 128GB of shared memory.

Design & Display
The Surface Laptop Ultra is a milled aluminum machine in Platinum and Nightfall, with a raised-pedestal design feeding a cooling system claimed to offer 2.5 times the thermal capacity of the Surface Laptop 7 — yet it stays under 18mm thick and 4.5 pounds. The 15-inch mini-LED touchscreen (3270 × 2180, 120Hz, 3:2, up to 2,000 nits peak HDR) is claimed to be 25 percent brighter than the MacBook Pro M5's panel, but it lacks pen support. Ports are generous: three USB-C (one with the world's first built-in magnetic USB-C charging), USB-A, HDMI 2.1b, a full-size SD card reader, and a headphone jack, plus Wi-Fi 7 and a 30-percent-larger haptic touchpad.
Performance
RTX Spark is NVIDIA's Grace-Blackwell data-center architecture shrunk into a laptop superchip: an Arm Grace CPU (up to 20 cores, co-developed with MediaTek) joined to a Blackwell RTX GPU (up to 6,144 CUDA cores) over NVLink-C2C, sharing one pool of up to 128GB of LPDDR5X memory. That shared pool is the whole argument — a 120-billion-parameter AI model can load on-device instead of in the cloud, and it brings full CUDA support to a Windows Arm machine, with DLSS 4.5 for gaming.
Performance Benchmarks
No independent final-hardware benchmarks exist — treat all numbers as preliminary. Microsoft's vendor measurements claim 2.1× faster first-token, 4.3× faster AI image generation, and 6.2× faster AI video generation than a 16-inch MacBook Pro with M5 Pro. The only independent testing was a pre-production sample: it lagged Apple's M5 Pro in Phoronix, Blender, and Cinebench, and games stuttered on unfinished drivers — but delivered identical performance on battery. Wait for launch-day reviews before judging the AI hype.
Local AI: The Headline Feature
Microsoft says the 128GB configuration can run 120-billion-parameter models locally at up to 1 petaflop of FP4 AI compute; its MAI Code 1.1 Flash coding model has been compressed to 53GB to run on-device, and Windows' new Hybrid Intelligence will split work between local and cloud models. Microsoft showed Gears of War: E-Day at full resolution and 120fps (with DLSS), with Call of Duty promised for RTX Spark in 2027. Windows on Arm still relies on emulation for older apps — check your software list first.
Battery & Charging
Microsoft claims up to 15 hours of typical use — and 99 percent of peak performance on battery. Peak system power is 90 to 140 watts under load, which will cut that figure sharply. Charging headlines the port story: a magnetic breakaway mechanism built into a standard USB-C plug, with a 140W adapter included during the pre-order window.
Price & Availability
Pre-orders opened October 7; shipping starts October 16. Eight configurations: from around $2,599 (18-core CPU, 5,120-core GPU, 24GB, 512GB, Platinum) through around $3,700 for the full 20-core/6,144-core chip with 32GB, up to around $5,899 for the 20-core chip with 128GB memory and 1TB storage. The memory tax is steep — 64GB to 128GB adds about $1,600 — but Microsoft offers up to $1,000 cashback when trading in an eligible MacBook Pro.
Verdict
The Surface Laptop Ultra is the most ambitious Windows laptop in years: workstation hardware with a real local-AI story, aimed at the MacBook Pro. But the $2,599 base model is a long way from the 128GB flagship, drivers are the risk factor, and independent benchmarks are pending. If you run large AI models locally and need CUDA on Windows, this is the machine to watch — everyone else should wait for reviews or buy the memory tier they actually need.
Pros and Cons
Pros:
- First laptop with NVIDIA RTX Spark — up to 128GB unified memory for large local AI models
- Brilliant 15-inch mini-LED display: 120Hz, 3:2, up to 2,000 nits peak HDR
- Generous ports including magnetic USB-C charging, USB-A, HDMI, and SD card reader
- 99 percent performance on battery and user-replaceable SSD
- Full CUDA support on a Windows Arm laptop
Cons:
- Memory pricing is punishing — 64GB to 128GB adds about $1,600
- No independent benchmarks of final hardware yet; prototype testing showed lagging performance and immature drivers
- Windows on Arm still needs emulation for older apps
- Touchscreen lacks pen support
- At 4.4+ lb, it is no ultraportable
