Key Takeaways
- RTX Spark delivers up to 1 petaflop of AI compute and can run 120 billion parameter models locally
- Microsoft Surface Laptop Ultra will support up to 128GB unified memory with a 2,000-nit mini-LED display
- Laptops from Asus, Dell, HP, Lenovo, MSI, and Microsoft will ship this fall
Nvidia has entered the mainstream laptop market with RTX Spark, a "superchip" that pairs its ARM-based Grace CPU with a Blackwell RTX GPU. The company claims the combination delivers up to 1 petaflop of AI computing power, enough to run 120 billion parameter models locally on a laptop.
Microsoft wasted no time announcing the first RTX Spark device: the Surface Laptop Ultra. It's positioned squarely against top-spec MacBook Pro models, with up to 128GB of unified memory and a 15-inch mini-LED touchscreen hitting 2,000 nits of HDR brightness.
“The RTX Spark isn't just a processor; it's an orchestration layer for the agentic era. We are moving from PCs that act as tools to PCs that act as teammates.”
— Jensen Huang, CEO of Nvidia
What's Inside the RTX Spark
The chip combines Nvidia's 20-core Grace CPU with a Blackwell RTX GPU packing 6,144 CUDA cores. That's the same CUDA count as the desktop RTX 5070. It also includes fifth-generation Tensor Cores and a unified memory system that can scale from 16GB to 128GB of shared RAM.
Nvidia says RTX Spark can render 3D scenes over 90GB in size, edit 12K video at 4:2:2 color depth, and run games at 1440p above 100 frames per second. Power consumption ranges from single-digit watts during light tasks to 80W at full load. The company promises "all-day" battery life, though specific runtime figures haven't been shared.
Adobe has committed to optimizing Photoshop and Premiere for the platform, claiming a potential doubling of AI and graphics performance. The company didn't specify what baseline it's comparing against.
Agentic AI Gets Hardware Support
RTX Spark includes new features designed specifically for AI agents in Windows. Nvidia introduced new "primitives" to help run agents securely, along with an OpenShell system that defines what an agent can and cannot do on the device.
The unified memory architecture is key here. With up to 128GB of RAM shared between CPU and GPU, the chip can handle models with over 1 million tokens of context. That's large enough for agents to maintain extended conversations or work with substantial documents without offloading to cloud servers.
Surface Laptop Ultra Takes Aim at Apple
Microsoft's Surface Laptop Ultra isn't being subtle about its target. The company is marketing it directly against high-end MacBook Pro models and other premium workstations for creative professionals.
“The Surface Laptop Ultra represents the pinnacle of Windows on Arm, finally closing the gap with professional-grade mobile workstations while retaining the mobility of a premium thin-and-light laptop.”
— Satya Nadella, CEO of Microsoft
The hardware reflects this positioning. Beyond the 2,000-nit mini-LED touchscreen, the Ultra includes what Microsoft calls the largest haptic trackpad ever put on a Surface device. Port selection covers USB-C, USB-A, HDMI, and an SD card reader, addressing a common complaint about port-limited ultrabooks.

Microsoft hasn't announced pricing, but expectations are high. The more modest Surface Laptop 8 and Surface Pro 12 start at $1,950. The Ultra will almost certainly cost more, likely pushing into the $3,000+ range that Apple's M-series Ultra machines occupy.
Who Else Is Building RTX Spark Machines
Microsoft won't be alone for long. Asus, Dell, HP, Lenovo, and MSI all have RTX Spark laptops and compact desktops coming this fall. Acer and Gigabyte have promised their own systems later, though they haven't committed to specific dates.
The variety of manufacturers suggests Nvidia is positioning RTX Spark as a platform play, not just a single-device showcase. If the chip delivers on its performance claims, it could finally give Windows on ARM the credibility it's lacked since Qualcomm's Snapdragon X series fell short of Apple Silicon comparisons.
What the Community Is Saying
Discussion on Reddit's r/hardware and Hacker News has been cautiously optimistic. Enthusiasts are excited about running large language models locally without cloud dependencies. The unified memory architecture draws favorable comparisons to Apple's M-series chips, which use a similar approach.
Skepticism centers on two areas: thermals and price. Fitting 80W of power consumption into a thin laptop chassis raises questions about sustained performance under load. And with the Surface Laptop Ultra likely priced above $3,000, some question whether the audience is large enough to shift the Windows laptop market meaningfully.
