NVIDIA unveils RTX Spark chip for laptops and desktop PCs

NVIDIA unveiled the RTX Spark system-on-a-chip at Computex 2026, featuring up to 20 Arm CPU cores, a Blackwell GPU with 6,144 CUDA cores, and 128GB of memory for laptops and desktop PCs. The chip will power high-end laptops from Dell, HP, Lenovo, Asus, MSI, and a new Microsoft Surface Ultra, positioning it as a direct competitor to Apple's M-series chips for gaming and creative tasks. The RTX Spark devices are planned for late 2026, with pricing yet to be announced.

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.
