NVIDIA RTX Spark Is an Arm Chip for Slim Gaming PCs

NVIDIA is putting a 20-core Grace Arm CPU and 6,144 Blackwell CUDA cores on a single chip thin enough for a 14mm laptop. Unveiled at Computex 2026, RTX Spark is the company's first serious move into Arm-based Windows gaming, pairing that silicon with up to 128GB of unified memory and what NVIDIA bills as 1 petaflop of AI compute. The target is ultra-slim 14mm laptops and compact desktops, a form factor where traditional discrete GPUs have always been a compromise. ASUS, Dell, HP, and Lenovo have devices planned for fall 2026, though pricing hasn't been disclosed. For gaming, the honest question is how a unified-memory Arm setup handles titles built for x86 and discrete GPU VRAM budgets. The more interesting pitch is the AI workload angle — Spark is positioned as a personal AI agent machine that also plays games, which is a different value proposition than any previous gaming laptop. Apple proved Arm can win on laptops; NVIDIA is betting it can do the same for Windows.
