For 40 years, using a PC has meant the same routine: open an app, click around, type something in. Nvidia and Microsoft are now selling a chip designed to make all of that optional.
On Monday, the two companies unveiled RTX Spark, a new Nvidia processor built to run AI directly on Windows laptops instead of in the cloud. The pitch is that you stop launching apps and start asking the computer to handle tasks for you, with the AI doing the actual work right there on your machine.
"For forty years, you launched apps. Click. Type. With RTX Spark and Microsoft Windows, you ask, and the PC does the work," Jensen Huang, Nvidia's founder and CEO, said at the launch. Satya Nadella framed it as Microsoft's bet to deliver "unmetered intelligence to every home and every desk."
The specs are aggressive for a laptop chip:
- Up to 1 petaflop of AI performance packed into laptops as thin as 14mm and as light as 3 pounds.
- 128GB of unified memory, enough to run a 120-billion-parameter AI model locally with a 1 million token context window. That's the kind of workload most people today have to rent cloud servers to handle.
- 14- to 16-inch OLED displays, all-day battery, and aluminum chassis, putting the laptops squarely in MacBook Air and Surface Laptop territory.
The market noticed immediately. Intel and AMD stocks tumbled on the news, since Nvidia is now openly muscling into PC chips, the one major computing category where it's never had real share.
The picture is more complicated than Nvidia is letting on. Apple's M5 Max, available now, actually has roughly twice the memory bandwidth of RTX Spark, which matters a lot for the kind of large language models Nvidia is showcasing in its marketing. Qualcomm's Snapdragon X2 Elite laptops are also shipping months earlier than RTX Spark, which doesn't land until fall. And Nvidia hasn't announced pricing for the laptops at all, making it impossible to know if these will compete on cost or sit in premium territory.
Where Nvidia might have a real edge is the software story. Dillon Rolnick, CEO of AI lab Nous Research, said the chip changes the math on what a laptop is in the first place: "You realize you're buying a full-fledged assistant, not a typical laptop." That framing matters because it's the first time a major PC launch has been pitched primarily around running AI agents locally rather than around the usual specs like clock speed or graphics performance.
The shift tracks with what's been happening on the coding side. The industry started with cloud-based tools, moved to running swarms of agents in parallel, and is now figuring out how to put that on a personal device. RTX Spark is essentially the hardware bet that the next stage of AI runs on your desk, not in someone else's data center.
The "ask, don't click" pitch is a big swing, and it depends on something Nvidia and Microsoft can't control: whether the agents are actually good enough to trust with your work. Most people still launch apps because the apps work and the agents don't, at least not reliably. If RTX Spark ships in the fall and the agent experience still feels like a beta, this becomes a very expensive Intel competitor with a slogan attached. But if local agents catch up to the cloud versions by the time these laptops are on shelves, Nvidia will have quietly rewritten what a PC is for, and Intel and AMD will be the ones explaining themselves to investors.
