NVIDIA just dropped its first Windows on Arm drivers for RTX Spark, a single-chip monster packing Grace CPU, Blackwell GPU, and 128 GB unified memory. Fall launch is locked. The 616.00 developer preview targets the Microsoft Surface RTX Dev box, which is a fully fanless unit. CUDA 13.4 toolkit handles native Arm64 builds and cross-compiling from x86_64 machines.
Devs can begin migrating apps on existing rigs before the hardware even ships. Fair warning, though. The preview has some jank. Pageable memory transfers run slower than expected, the display goes blank for about two minutes during install, and PyTorch CI workflows can trigger GPU timeouts that crash the whole system. Nsight Copilot is also completely disabled here.
Hands-on units at Computex 2026 showed legit chops in AI workloads, content creation, and gaming. This is NVIDIA's first real swing at laptops and the AI PC space. Early leaked benchmarks are from engineering samples, though, and those don't reflect retail performance at all. The real verdict waits until fall units hit shelves.
