Nvidia RTX Spark brings 6,144 GPU cores to Windows PCs this fall
Nvidia's RTX Spark marks the company's first complete consumer PC processor, threatening Intel and AMD's dominance in the $120 billion laptop chip market.
Nvidia's entry into the PC processor market with the RTX Spark super chip threatens to upend Intel and AMD's decades-long hold on Windows laptops, bringing 6,144 Blackwell GPU cores and a 20-core Arm CPU to consumer machines for the first time.
"The chips and the OS must evolve for a world of agents running continuously, getting work done," Nvidia Chief Executive Jensen Huang said at Computex in Taipei on Monday. "That is the modern application: an AI agent."
The RTX Spark, built on TSMC's 3nm process with MediaTek, packs 128GB of unified memory connected via a 600 GB/s NVLink and delivers 1 petaflop of AI performance — roughly equivalent to an RTX 5070 desktop GPU. The chip scales from single-digit watts to 80 watts, allowing it to power thin 14mm laptops weighing as little as three pounds. Nvidia claims the platform can edit 12K resolution video, render 90GB 3D scenes, and run 120-billion-parameter large language models with up to 1 million tokens of context locally.
Dell Technologies rose 11% and HP gained nearly 9% on Monday as investors bet the new chips will drive a PC refresh cycle. Nvidia's PC business remains a fraction of its data center revenue, but the move positions the company to capture a slice of the $120 billion annual PC processor market currently split between Intel, AMD, and Apple.
The RTX Spark is effectively the same GB10 chip inside Nvidia's DGX Spark "personal AI supercomputer" released last year, now repackaged as a family of consumer processors. The flagship N1X variant uses 20 Arm cores — a mix of Cortex-X925 "extreme" cores and Cortex-A725 efficiency cores — paired with either 6,144 or 5,120 CUDA cores. A lower-end N1 variant will offer 12 or 10 CPU cores with 2,560 or 2,048 CUDA cores, roughly matching a GeForce RTX 2050.
Eight laptop models are confirmed for this fall, including Microsoft's Surface Laptop Ultra — which Surface chief Andrew Hill called "the most powerful thing we've ever made." Asus, Dell, HP, Lenovo, and MSI showed RTX Spark laptops at Computex, with Acer and Gigabyte following in a second wave. Nvidia said partners are developing more than 30 laptops and over 10 desktops total.
The chip's AI capabilities are the centerpiece of Nvidia's pitch. Microsoft and Nvidia are building new Windows security primitives and an OpenShell runtime that "allows personal agents to run safely and under full user control," according to Microsoft. Adobe has pledged native support across Premiere, Photoshop, and Substance 3D, with a new video pipeline tapping into the RTX Spark's unified memory architecture.
But questions remain about whether the always-on, always-connected vision of "agentic AI" works in a laptop form factor. Gaming laptops with powerful GPUs typically last only a few hours on battery, and Nvidia declined to provide specific battery life estimates. Senior product manager Mark Aevermann said only that users "won't need a charger" under light workloads, while the chip can draw up to 80 watts under full load — enough to drain a large battery in roughly an hour.
Nvidia also faces the Arm compatibility challenge. Legacy Windows software built for Intel and AMD's x86 processors must run through Microsoft's Prism emulator, which can reduce performance. However, Microsoft has spent years optimizing Prism for Qualcomm's Arm chips, and Nvidia claims its graphics and AI capabilities will push the platform further. Riot Games is bringing League of Legends and Valorant to Windows on Arm, and Epic's Fortnite already arrived last November.
The competitive stakes are high. Intel's client computing group generated $29.3 billion in revenue last year, while AMD's client segment brought in $7.1 billion. Apple's M-series chips have already demonstrated the performance-per-watt advantages of Arm architecture in PCs, capturing significant market share. Nvidia's entry adds a third Arm competitor to the Windows market alongside Qualcomm, potentially accelerating the industry's shift away from x86.
Nvidia shares have gained more than 150% over the past 12 months, driven by data center AI demand. The RTX Spark represents a bet that the same AI tailwind can revive the PC market, which shipped about 250 million units last year. If even a fraction of those machines adopt Nvidia's chips, the revenue contribution could become material.
