As experienced Pi users, we've run desktops on earlier models, but they felt sluggish. The Pi 4 delivers smooth performance for everyday tasks. Pair it with up to 4GB RAM, dual micro HDMI ports for two 4K displays, and external storage for a capable setup. It's ideal for browsing, office work, and light productivity—not heavy 3D rendering, but more than enough for most users.
Off-the-shelf devices like Fire TV or Roku are convenient, but building your own offers customization and cost savings. The Pi 4's hardware excels at 4K playback. Install your preferred Linux distro with OSMC (Open Source Media Center), and enjoy seamless streaming from Plex, Kodi, or other services.
RetroPie turned older Pis into emulation powerhouses for classics. The Pi 4 pushes boundaries further, handling demanding emulators like N64 or Dreamcast smoothly. Skip RetroPie for manual setups to maximize performance—we've tested dozens of titles, and the results impress.
Ditch CDs or phone tethering for a dedicated hi-fi solution. Connect a USB DAC to your Pi 4 and stream lossless audio from your library. Enhanced processing decodes high-bitrate files effortlessly, outperforming prior models for audiophiles.
Valve discontinued the standalone Steam Link, but the Pi 4 revives it perfectly. Install the official Steam Link app, stream PC games to your TV—no need to relocate your rig. The Raspberry Pi Foundation tested it themselves with great success.
These are just starting points—endless projects await. For peak performance, manage heat with our guide to keeping your Raspberry Pi cool.
