Microsoft launches Surface RTX Spark Dev Box for local AI computing

Microsoft announced the Surface RTX Spark Dev Box, a compact desktop‑class PC built around NVIDIA's RTX Spark silicon, which combines an NVIDIA Grace ARM CPU and a Blackwell RTX GPU. The system delivers up to 1 petaflop of AI‑focused compute, 128 GB of unified memory and can run large language models with more than 120 billion parameters and context windows of up to one million tokens, enabling developers to train, fine‑tune and infer AI models locally without relying on cloud services. The device ships with Windows 11 Pro, a developer toolset including VS Code, GitHub Copilot and CUDA support, and is planned for U.S. availability in 2026.

Separately, a leak reported in Italy suggests Microsoft is preparing a new Surface Pro 13 powered by a Snapdragon X2 Elite ARM processor, up to 32 GB of RAM, and an on‑device NPU delivering 80 TOPS for AI workloads. The 13‑inch OLED tablet is described as a premium 2‑in‑1 device with local AI capabilities, a replaceable PCIe 4.0 SSD and a scheduled launch on 16 June 2026.
