NVIDIA unveils RTX Spark at Computex: 20-core Arm CPU, 6,144 CUDA cores, 128GB unified memory at 45-80W. Microsoft's Surface Laptop Ultra debuts as first partner. PC industry shaken.

Today at Computex Taipei, Jensen Huang's keynote was packed with bombshells. Fresh off announcing the DGX Station for Windows (a trillion-parameter desktop supercomputer), he dropped a second curveball — RTX Spark. This marks NVIDIA's return to consumer CPUs after more than a decade, and they're coming in hot with an Arm architecture, unified memory, and desktop-class GPU — taking on Intel, AMD, and Qualcomm head-on. Microsoft has already thrown its weight behind the platform: the brand-new Surface Laptop Ultra is built entirely around RTX Spark, from chip to system. Let's unpack what makes this thing so formidable. RTX Spark (formerly codenamed N1X) is a complete system-on-chip with two dies connected via NVLink-C2C high-speed interconnect. On the CPU side: 20 custom Grace Arm v9.2 cores co-developed with MediaTek. On the GPU side: a Blackwell RTX GPU packing 6,144 CUDA cores — matching the desktop RTX 5070. It features up to 128GB of unified LPDDR5X memory shared between CPU and GPU, delivers 1 petaFLOPS (FP4) of AI compute, and sips just 45-80W in laptop form. In plain English: NVIDIA has crammed desktop-class discrete GPU performance into a laptop chip drawing under 80W.
