xtop is a live GPU and NPU monitoring application with a text-based user interface (TUI), developed by publisher Mengsheng Wu for the Windows operating system. Its stated purpose is to provide real-time visibility into the activity and status of graphics processing units and neural processing units, presenting this information directly in a terminal-style display rather than through a conventional graphical window. This places the software in the system utilities category, specifically among hardware monitoring and diagnostic tools, a group of applications commonly used by developers, system administrators, power users, and enthusiasts who need to observe how accelerators behave under workload. Relevant use cases include watching GPU utilization while running graphics-intensive or compute-intensive applications, observing NPU activity during on-device machine learning or AI inference tasks, verifying that hardware accelerators are being engaged as expected by particular software, and keeping an eye on accelerator behavior during development, benchmarking, or troubleshooting sessions on Windows machines. Because the interface is terminal-based, the tool fits naturally into command-line workflows and can be run alongside other console utilities without requiring a separate desktop application window. The current version of xtop is 0.1.1, and this is the only release currently listed in the catalog, with the version history containing a single entry. As an early-stage release carrying a 0.x version number, xtop represents an initial public iteration of the project rather than a long-established product line, so no comparison across multiple published versions is applicable at this time. Users evaluating the software should note that version 0.1.1 is both the latest and the sole available release, and that the catalog description focuses on the core capability of live GPU and NPU monitoring on Windows without documenting additional features, configuration options, or platform variants beyond that stated scope.
