NVIDIA announces RTX Spark — 'the most efficient PC chip ever built'

NVIDIA has officially announced the RTX Spark, a new Arm-based system-on-chip designed for Windows PCs, at Computex 2026 in Taipei. CEO Jensen Huang described it as "the most efficient PC chip ever built" and confirmed it would target multiple price points.

The chip features 6,144 CUDA cores — the same count as the upcoming desktop RTX 5070 — bringing full ray tracing, DLSS 4 with Multi Frame Generation, and DirectX 12 Ultimate support to the Windows on ARM platform.

Microsoft is the lead launch partner, showcasing the Surface Laptop Ultra as the first RTX Spark device. Dell, HP, Lenovo, and ASUS are also confirmed as OEM partners, with additional manufacturers expected to announce devices in the coming months.

The announcement marks NVIDIA's first direct entry into the consumer PC CPU market, putting it in competition with Intel (x86), AMD (x86), and Qualcomm (Snapdragon X Arm).
