The Raspberry Pi 5 is not the fastest single-board computer you can buy, nor the cheapest, nor the one with the most I/O — Rockchip RK3588 boards from Orange Pi and Radxa beat it on cores, NVMe, and 2.5GbE for less money. So why is the Pi still the default? Its moat is software and supply: a purpose-built OS, thousands of compatible HATs, the best documentation and community in the category, and a committed production lifetime that the clones can't match. This guide maps the whole landscape — the RK3588 challengers, the proven Odroid, NVIDIA's CUDA-powered Jetson, x86 N100 mini-PCs, and the ESP32 microcontroller floor — and gives you an honest framework for picking the right board instead of the most-hyped one.
