Microsoft and Nvidia jointly announced today the launch of a new flagship laptop, Surface Laptop Ultra. This is Microsoft's first bet on Arm-based Nvidia chips for flagship portable devices after many years.
This Surface Laptop Ultra uses a 15-inch mini-LED touch screen with a pixel density of 262 PPI. It is officially called the "brightest ever" Surface display, with an HDR peak brightness of up to 2,000 nits, and is equipped with the largest trackpad in the current Surface series. The body is available in dark gray and silver colors and weighs within 4.5 pounds (approximately 2 kilograms), positioning it as a high-end flagship mobile productivity device.
Surface business leader Andrew Hill said that Surface Laptop Ultra is "the most powerful Surface device Microsoft has ever built," emphasizing that this is a new high point in the series' performance. This new product is built-in NVIDIA's latest RTX Spark "super chip", which is the Windows 11 version of the chip used in the previous DGX Spark mini host for AI developers. It is adapted and optimized for notebook and desktop PC scenarios.
According to information previously disclosed by Nvidia to the media, the RTX Spark chip is equipped with up to 20 CPU cores, 6144 GPU cores, and supports up to 128GB of unified memory. Some models start from 16GB of memory. The entire product line will cover different price segments in the future. In terms of energy efficiency, the chip focuses on "all-day battery life". Its graphics performance is roughly equivalent to the RTX 5070 notebook-level graphics card, and it can provide up to about 1 Petaflop level of AI computing power for emerging scenarios such as generative AI and local reasoning.
In terms of body interfaces, Surface Laptop Ultra does not take the extremely thin and light route, but retains a relatively complete physical port layout. The fuselage is equipped with USB-C, USB-A, HDMI, a full-size SD card slot and a 3.5mm headphone jack. Judging from the product pictures, up to three USB-C interfaces may be provided on the side of the fuselage, but Microsoft has not yet disclosed the specific bandwidth specifications or protocol version support of each interface.
In its official blog this time, Microsoft remained restrained on the specific configuration and pricing of this new product, and did not announce a detailed model matrix and price range. In contrast, the official promotional language emphasizes the positioning of the brand and design, such as "no boundaries, no compromises", "every micron counts", "this is the most thoughtful embodiment of Surface craftsmanship", "such a machine should not stand still, but be pushed to the limit", etc., trying to build Surface Laptop Ultra into a high-end creation and productivity tool for "world creators".
Judging from the statements of Microsoft and Nvidia, Surface Laptop Ultra is not the only device using RTX Spark chips. It is expected that more notebooks and mini hosts equipped with this platform will be launched this fall. However, Microsoft plays a core role in this ecosystem. The two parties have been working together for many years to prepare Windows support for Arm devices including RTX Spark, and to optimize the system layer and developer ecosystem.
Nvidia disclosed in its RTX Spark introduction that this family of chips is being extended to a wider range of PC forms, while Microsoft explained some of the system optimizations for RTX Spark in its own blog, including attracting support from developers and software manufacturers in the direction of Windows on Arm. With the debut of Surface Laptop Ultra, the competitive landscape of Arm-based high-performance Windows devices in the PC market is expected to usher in a new round of changes this year.
