Apple Silicon changed what people expected from laptop chips. Qualcomm’s Snapdragon X tried to bring that same efficiency to Windows. Now NVIDIA and MediaTek have arrived at Computex 2026 with something that makes both look like opening acts. RTX Spark is official and NVIDIA is calling it “the most efficient PC chip ever built.”
That’s a bold claim. The specs behind it are even bolder.
RTX Spark combines a 20-core NVIDIA Grace ARM CPU, Blackwell RTX GPU with 6,144 CUDA cores, up to 128GB unified LPDDR5X memory, and 1 petaflop of AI compute performance into a single chip designed for thin laptops and compact desktops running Windows 11. MediaTek handled CPU design, memory controller technology, power management, and wireless connectivity. NVIDIA brought its Blackwell GPU architecture, DLSS, RTX, CUDA ecosystem, and AI platform. Two companies solving different halves of the same problem simultaneously.
The AI story is the headline. 1 petaflop one quadrillion operations per second enables RTX Spark to run 120 billion parameter AI models locally with context windows of up to 1 million tokens. That means powerful AI assistants operating entirely on your device without sending data to the cloud. Microsoft is already building Windows optimizations specifically for AI agents running on RTX Spark hardware.
Gaming gets equal attention, something ARM-based PC chips have historically avoided. NVIDIA claims AAA gaming at 1440p above 100fps even unplugged, with performance comparable to an RTX 5070 Laptop GPU. DLSS, Reflex, G-SYNC, and OptiX all come along for the ride.
Adobe is rebuilding Photoshop, Premiere Pro, and Firefly tools specifically for RTX Spark claiming up to 2x faster AI workflows. NVIDIA demonstrated editing 12K video, rendering 90GB 3D scenes, and generating 4K AI video on the chip during Computex. The day of the announcement, AMD, Intel, and Qualcomm shares all dropped. NVIDIA’s rose.
Microsoft Surface Ultra, Dell, HP, Lenovo, ASUS, MSI, Acer, and Gigabyte are all building RTX Spark devices arriving fall 2026. Pricing hasn’t been confirmed except the premium tier to start.
The PC chip landscape looked settled two weeks ago. RTX Spark just reshuffled every assumption about what a Windows laptop can do and fall 2026 is when buyers find out if the performance claims hold up in the real world.
