NVIDIA unveils RTX Spark chip for laptops and desktop PCs

It was an open secret that NVIDIA was working on an ARM-based system-on-a-chip for laptops and desktops, and today at Computex 2026 the company unveiled what it’s been working on. It’s surely a beast, and unsurprisingly, it’s lathered in “AI” buzzwords. At full strength, this chip offers up to 20 Arm CPU cores, a Blackwell GPU with 6,144 CUDA cores, 128GB of LPDDR5X RAM, and up to 300 GB/s of memory bandwidth. That powerful CPU and GPU, connected over NVLink C2C, and the large memory pool give AI agents and 120-billion-parameter models plenty of power and space for long-running tasks with context lengths stretching to a million tokens, according to Nvidia. RTX Spark will power high-end laptops from partners including Dell, HP, Lenovo, Asus, and MSI — and notably, a new Surface Ultra laptop from Microsoft. Nvidia says it’s worked with those partners to create “the most extraordinary laptops ever built,” with tandem OLED G-Sync displays, “all-day” battery life, premium aluminum chassis with large glass touchpads. ↫ Jeffrey Kampman at Tom’s Hardware I couldn’t care less about the “AI” nonsense, but the chip itself seems like an absolute monster for laptops and mini PCs. With that much power and a solid NVIDIA GPU, these are also great for gaming and creative tasks, making them feel like the first true competition in the PC space to Apple’s M series of chips. They’re planned for late 2026, and tellingly, there’s no pricing information just yet.
