Raspberry Pi 4 Model B 2019 Quad Core 64 Bit… vs Raspberry SC15184 Pi 4 Model B 2019 Quad Core 64… — Head-to-Head (2026)

Our verdict

Raspberry Pi 4 Model B 2019 Quad Core 64 Bit… is our pick.

The 4GB Raspberry Pi 4 Model B is the better buy for almost every 2026 use case. It doubles the LPDDR4-2400 memory for a moderate premium, and 4GB is the practical floor for containerized homelab work, browser-based desktop use, and PS2-era emulation front-ends. The 2GB board only wins if your workload is a single-purpose appliance (Pi-hole, RetroPie up to fifth-gen, headless MQTT broker) where the extra spend buys you nothing.

Buy the 4GB Raspberry Pi 4 Model B if you're running Docker stacks, a desktop environment, Home Assistant with add-ons, or emulation front-ends that hold large box-art libraries in memory. Buy the 2GB SC15184 if you're building a dedicated single-service appliance where 2GB is genuinely sufficient: Pi-hole, PiVPN, a print server, or a RetroPie box that stops at fifth-generation consoles.
