Is the 1GB model worth buying?

For headless jobs like Pi-hole, Home Assistant or a small file server, yes. For a desktop or anything with a browser, spend a little more on the 2GB or 4GB board.

How does it compare with the Raspberry Pi 3B+?

It is much faster: a 1.5GHz Cortex-A72 quad-core, USB 3.0, true gigabit Ethernet and dual HDMI. The 3B+ has only 1GB RAM too, so the Pi 4 1GB is the better buy at a similar price.

What power supply does it need?

A 5V/3A USB-C supply. Underpowered chargers cause throttling and undervoltage warnings, especially with USB peripherals attached.

Does it need a heatsink or fan?

Under sustained load it gets hot and throttles. A case with ventilation plus a small heatsink or fan keeps clocks steady.

The board only. You need to supply a USB-C power adapter, microSD card, case and cables; many kits bundle these.

Prices on the 1GB board tend to dip when the 2GB and 4GB models are promoted or when a new Pi generation launches. Compare across stores before buying.

Our take on the Raspberry Pi 4 Model B 1GB

The Raspberry Pi 4 Model B 1GB is a credit-card-sized single-board computer with a quad-core Broadcom BCM2711 at 1.5GHz, 1GB of DDR4 RAM, dual micro HDMI outputs up to 4K, true gigabit Ethernet, USB 3.0 and Bluetooth 5.0. It is the entry configuration of the Pi 4 line, so it runs the same software and HATs as the 2GB, 4GB and 8GB versions but with the least headroom. The 1GB model is the cheapest way into Pi 4 hardware, though it has been largely superseded in value by the 2GB board.
