A 4 GB single-board computer with a 1.50 GHz quad-core 64-bit processor, dual-band wireless, Bluetooth, and USB 3.0 and 2.0 ports
The Raspberry Pi 4 Model B is a single-board computer with a quad-core 64-bit processor running at 1.50 GHz and 4 GB of RAM. It suits hobbyists, educators and developers building compact projects that need wireless connectivity. The board includes Bluetooth and Wi-Fi as standard.
Two USB 3.0 ports and two USB 2.0 ports provide peripheral expansion, though total bus power is shared across all four ports. High-draw devices such as mechanical drives may require a powered hub to operate reliably. Bandwidth on the USB 2.0 ports remains capped at legacy speeds.
The fixed 4 GB of RAM cannot be upgraded, so the board fits workloads that stay within this memory ceiling. Applications needing more memory will require a different platform. Buyers who want more storage should note the board relies on a microSD card for primary storage.

The 4 GB model suits desktop use, light coding, and media playback; the 2 GB and 1 GB versions handle headless or lighter tasks.
The 1.50 GHz quad-core 64-bit CPU runs desktop apps, web browsing, and compilation smoothly without active cooling in most cases.
USB 3.0 ports deliver up to 5 Gbit/s for fast storage, while USB 2.0 ports handle keyboards, mice, and low-bandwidth devices.
