NVIDIA's RTX Spark is an ARM-powered SoC that's expected to compete directly with the likes of Intel, AMD, and Qualcomm for space in Windows 11 PCs. I covered rumors of the "N1X" chip for months in the lead-up to Computex 2026, and indeed it seems just as powerful and efficient as pre-announcement estimates. Spark takes efficient ARM-based CPU cores similar to those found in Qualcomm Snapdragon chips and pairs them with an NVIDIA Blackwell RTX GPU, all while drawing from a unified memory setup that can hit 128GB. This combination allows for massive performance that can shred standard and AI-re
