Jensen Huang Drops the Bombshell: NVIDIA RTX Spark Launches, Arm Laptops Take on Intel Head-On

📡 AI News 💬

🩺 Summary

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.

📝 Details

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.
