What Is the NVIDIA RTX Spark Processor in the Surface Laptop Ultra?

The NVIDIA RTX Spark is an ARM-based system-on-chip designed by NVIDIA in collaboration with MediaTek, and it serves as the processing core for the Surface Laptop Ultra. The SoC integrates 20 Grace CPU cores, 6,144 Blackwell RTX GPU cores, 5th-generation Tensor Cores, and 128GB of Unified Memory, with each component connected via its own NVLink-C2C interconnect link.

NVIDIA states that the chipset outputs 1 Petaflop of FP4 performance. The RTX Spark was officially announced by NVIDIA ahead of Computex 2026, and Lowyat.NET has described it as a “coveted chip” for next-generation laptops.

The NVIDIA RTX Spark SoC delivers 1 Petaflop of FP4 performance through 20 Grace CPU cores, 6,144 Blackwell RTX GPU cores, 5th-generation Tensor Cores, and 128GB of unified memory over NVLink-C2C interconnects.

Who Will Speak at the October 7 Microsoft Event?

Microsoft CEO Satya Nadella, NVIDIA CEO Jensen Huang, and Microsoft Executive Vice President of Windows & Devices Pavan Davuluri are all confirmed to attend the October 7, 2026 event in San Francisco. The trio is expected to share their latest innovations across Windows, NVIDIA RTX Spark, and the Surface lineup in the “broader PC ecosystem.”

In the lead-up to the event, Microsoft has posted on its social media accounts, though the posts lack specific details beyond promoting the Surface Laptop Ultra. A post from the official Microsoft Surface account on X dated September 15, 2026 stated:

Get ready for the next step. — Microsoft Surface (@surface) on X, September 15, 2026

Satya Nadella, Jensen Huang, and Pavan Davuluri are confirmed speakers at Microsoft’s October 7, 2026 event, which will cover Windows, NVIDIA RTX Spark, and the Surface lineup in the broader PC ecosystem.

Will Microsoft Release Multiple Surface Laptop Ultra Configurations?

It is unknown at this time whether Microsoft plans to release multiple SKUs of the Surface Laptop Ultra. Microsoft has not disclosed configuration details beyond the RTX Spark processor with 128GB of unified memory, and its social media posts have not revealed additional SKU information.

Context for this question comes from Asus, which is planning to release five configurations of its RTX Spark-powered ProArt P14 laptop. These configurations consist of different Unified Memory capacities, ranging from 24GB to the full 128GB of LPDDR5X. Whether Microsoft will adopt a similar multi-configuration strategy for the Surface Laptop Ultra has not been confirmed.

Microsoft has not confirmed whether multiple Surface Laptop Ultra SKUs will be offered, while Asus has announced five ProArt P14 configurations ranging from 24GB to 128GB of unified memory.

Who Is the Surface Laptop Ultra For?

The Surface Laptop Ultra is positioned for users who require substantial on-device AI processing power, given its 1 Petaflop of FP4 performance, 128GB of unified memory, and 6,144 Blackwell RTX GPU cores. The event’s stated focus — “how local AI will shape the next chapter of the PC” — reinforces that local AI inference is the primary use case.

Developers, AI researchers, and power users within the Windows ecosystem are the likely target audience, particularly those who need to run AI workloads without cloud dependency. The joint appearance of Microsoft and NVIDIA leadership at the launch event also signals an enterprise-focused positioning for the device.

The Surface Laptop Ultra targets developers, AI researchers, and power users who require on-device AI inference with up to 128GB of unified memory and 1 Petaflop of FP4 performance.
