Frequently Asked Questions

Q1: Is 1GB RAM enough for Raspberry Pi 4?
For headless server use cases - IoT gateways, MQTT, Node-RED, home automation - 1GB is perfectly adequate. For desktop use or browser-heavy workloads, the 4GB or 8GB variant is recommended.

Q2: What's the difference between Pi 4 and Pi 3?
The Pi 4 offers a 2-3x faster CPU (Cortex-A72 vs A53), True Gigabit Ethernet, USB 3.0, dual 4K display output, and USB-C power - a major generational leap.

Q3: What power supply does Raspberry Pi 4 need?
A quality 5V/3A USB-C power supply is required. The official Raspberry Pi 15.3W USB-C Power Supply is recommended to avoid low-voltage warnings and USB throttling.

Q4: Can Raspberry Pi 4 1GB run Docker?
Yes, for lightweight single containers. For running multiple containers simultaneously, the 4GB or 8GB variant offers more headroom.

Q5: Is Raspberry Pi 4 still worth buying in 2025?
Yes - the Pi 4 has a massive ecosystem, extensive OS support, and is ideal for production deployments, classroom use, and projects where proven stability matters more than cutting-edge performance.
