Microsoft Surface Laptop Ultra is showcased running on the Nvidia RTX Spark system-on-chip, which integrates an Arm CPU and an Nvidia Blackwell GPU. This architecture allows devices to be thinner and lighter with longer battery life while maintaining high performance. Details on native Arm application support are tracked at worksonwa.com.

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

The platform supports native execution for major creative and productivity tools. Creative applications such as Adobe Photoshop, Adobe Premiere, and DaVinci Resolve run natively to handle demanding tasks like 4K60 video editing. Productivity suites including Microsoft Office, Microsoft Edge, and Google Chrome also feature full native Arm compatibility.
For applications that do not run natively on Arm, Windows utilizes the Prism translation layer. Prism automatically translates x86 instruction sets into Arm instructions, allowing older or unoptimized software to run on the system. This translation layer ensures compatibility across a broader ecosystem of legacy software.
The unified memory architecture of the Nvidia RTX Spark chip provides up to 128GB of shared memory across the CPU and GPU. This shared memory pool allows the Blackwell GPU to load large AI models, supporting configurations of up to 120 billion parameters without the limits of discrete graphics card VRAM.
Microsoft also addresses the gaming ecosystem on Arm through compatibility updates. Anti-cheat support has been enabled for titles like League of Legends and Valorant from Riot Games, as well as Fortnite from Epic Games. The broader hardware ecosystem includes alternative Surface laptop models in 13-inch and 15-inch sizes alongside the Surface Laptop Ultra.
