AIDA64 vs htop

AIDA64 Extreme provides home users with detailed PC system information, live monitoring, benchmarking, and stress testing. It identifies processors, motherboards, graphics cards, memory, and storage. Other editions address business and network administration. AIDA64 Business monitors more than 250 sensor devices for temperatures, voltages, fan speeds, and power draw; it can collect hardware and software inventories from Windows computers on a corporate network. Business reports can be saved in open formats or an SQL database, and audit snapshots can be compared to identify changes and trigger real-time alerts. It also supports remote monitoring and control, including administrative tasks and file transfers. Network Audit is limited to inventory and does not include remote control, remote monitoring, diagnostics, or benchmarks available in other editions. AIDA64 supports more than 50 LCD and VFD screens, plus wireless sensor monitoring on smartphones and tablets. Products run on Windows, Android, and iOS, and are available for a 30-day trial. Listed one-time prices include 59.95 EUR for Extreme, 129.90 EUR for Network Audit, and 219.90 EUR each for Business and Engineer.

htop is a free, text-mode interactive process viewer for Linux and macOS. It runs in console or X terminals and requires ncurses, offering a command-line interface for watching and managing running processes. Current releases also list FreeBSD, NetBSD, OpenBSD, DragonFly BSD, and Solaris as supported systems. The project, founded in 2004, is distributed as source code on GitHub and as pre-compiled packages from operating-system distributors, with installation examples for Debian, Fedora, Gentoo, and Arch Linux; Homebrew includes it for macOS. Its display can show Unicode Braille graphs and a Unicode tree view, including visual support for large processor counts. Users can set I/O scheduling priority and CPU affinity, choose dark or light terminal themes, and customize header meters. The memory percentage covers process-used memory; htop does not provide a per-process SWAP column.
