For the last couple of years, Qualcomm has essentially dominated the ARM based Windows PC space. It started with the Snapdragon X Elite in 2024, and later expanded into the more capable Snapdragon X2 lineup in late 2025.
That period of Qualcomm being the only major player in Windows on ARM is now coming to an end, largely because Nvidia has entered the scene. The company unveiled its ARM based RTX Spark PC chips at Computex 2026, positioning them as a kind of “Apple Silicon moment” for Windows devices.
The announcement immediately shook the market, with Qualcomm shares dropping by over 10 percent in premarket trading and wiping out billions in value. That reaction alone highlights how significant Nvidia’s entry is.
So what are these chips, how do they differ, and which one actually matters more to users? Here is a breakdown.
1. What Is the Nvidia RTX Spark?
RTX Spark is Nvidia’s response to the rising trend of unified ARM based computing chips, similar to Apple’s M series and Qualcomm’s Snapdragon X lineup.
At its foundation, RTX Spark is built on the GB10 Grace Blackwell Superchip architecture used in Nvidia’s DGX Spark workstation. Nvidia has adapted it for consumer Windows laptops. It features a custom ARM CPU developed alongside MediaTek, a Blackwell based RTX GPU, and an integrated AI accelerator, all built on TSMC 3nm technology with around 70 billion transistors.
The specifications are very high end. RTX Spark can include up to 20 CPU cores, a 6,144 core Blackwell GPU, and as much as 128 GB of unified memory. Nvidia also claims more than 1 petaflop of FP4 AI performance, which means it can handle extremely large AI models locally without relying on the cloud.
The CPU and GPU communicate through NVLink C2C technology, providing up to 600 GB per second of bandwidth between components.
According to Nvidia, laptops powered by RTX Spark are expected in autumn 2026, with manufacturers like ASUS, Dell, HP, Lenovo, and Microsoft Surface already lined up.
