Nvidia and Microsoft have officially unveiled the RTX Spark, an Arm-based system-on-chip designed for Windows laptops and compact desktop computers.
Nvidia and Microsoft have officially entered the Arm-based Windows PC market with the launch of the RTX Spark, a new system-on-chip (SoC) co-developed with MediaTek [1]. The platform, which was teased ahead of Computex 2026 as a "new era of PC," is designed to power a new generation of Windows laptops and compact desktop computers [1, 2].
Key takeaways
The RTX Spark represents a significant shift for Nvidia, which had previously focused its Arm-based computing efforts on enterprise systems and developer-oriented mini PCs like the DGX Spark [1, 2]. The new consumer-focused SoC is based on the same silicon as the GB10 "Superchip" found in the DGX Spark, which Nvidia CEO Jensen Huang confirmed in September 2025 would be adapted for broader product lines [1]. The RTX Spark features a big.LITTLE CPU configuration with 10 cores each and a GPU capable of performance equivalent to the mobile version of the RTX 5070 [1].
To ensure the platform is competitive in the consumer market, Microsoft has implemented improvements to the Windows ARM to x86-64 emulator [1]. These updates include support for anti-cheat software such as BattlEye, Easy Anti-Cheat, and Vanguard, which are intended to bolster the gaming capabilities of the new hardware [1]. The development of this chip follows the expiration of a 2016 exclusivity agreement between Microsoft and Qualcomm, which had previously restricted the landscape for ARM-based Windows devices [1].
The introduction of the RTX Spark marks a major expansion of the Windows on Arm ecosystem, directly challenging the dominance of traditional x86 chipmakers like Intel and AMD [2]. By leveraging a unified memory architecture and high-performance AI capabilities, Nvidia and Microsoft are aiming to provide a platform that can handle advanced local AI tasks that were previously limited by the hardware constraints of earlier Copilot+ PCs [1, 3]. As the industry continues to move toward power-efficient, Arm-based computing, the success of the RTX Spark will depend on its ability to offer a seamless experience across the diverse range of laptops and desktops being produced by its third-party hardware partners [1, 2].

The RTX Spark is a system-on-chip (SoC) developed by Nvidia and MediaTek that combines a Blackwell GPU and an Arm-based CPU to run AI models locally on PCs.
Nvidia is partnering with MediaTek for chip design and with Microsoft, Dell, HP, ASUS, Lenovo, and MSI to integrate the chips into upcoming Windows PCs.
Nvidia is seeking to expand its AI footprint to the 'edge,' allowing advanced AI agents to run locally on consumer devices without needing constant cloud connectivity.
