Nvidia Just Built Its First PC Processor: Here's What the RTX Spark Means for Your Next Laptop

For decades, Nvidia has made the graphics card inside your Windows laptop, not the chip that runs it. Intel and AMD have mainly owned that part of the industry. But that changed at the Computex trade show in Taipei on June 1, where Nvidia CEO Jensen Huang unveiled the RTX Spark, the company's first processor designed to be the main brain of a Windows PC.

Nvidia, currently the world's most valuable company with a market cap above $5 trillion, built the chip in close partnership with Microsoft. Devices from Microsoft Surface, ASUS, Dell, HP, Lenovo, and MSI will carry it when they arrive this fall, with Acer and Gigabyte to follow.

"This reinvention of the computer is as big of a deal as the reinvention of the phone into what we now know as the smartphone," Huang told the audience in Taipei. "This is the first completely re-engineered, reinvented line of PCs that has happened in 40 years."

Tom's Guide, covering the keynote live, compared it to Apple's M1 moment in 2020, when Apple broke from Intel with its own custom chip and reshaped the entire laptop market.

What the RTX Spark chip actually does

RTX Spark fuses two processors into one package. One handles everyday computing, using a new custom 20-core processor called the N1X, developed alongside Taiwan's MediaTek. The other handles graphics and AI, using Nvidia's latest Blackwell GPU with 6,144 graphics cores. Both share a single pool of up to 128 gigabytes of memory, built on TSMC's 3-nanometer process.
