Is the 4GB model worth it over the 2GB or 8GB versions?

4GB is the middle option and suits desktop use, media centers and light servers. Choose 2GB for simple headless projects and 8GB only if you run heavy multitasking or virtual machines.

How is the Pi 4 different from the Pi 3?

The Pi 4 has a faster quad-core CPU, LPDDR4 RAM, dual micro-HDMI 4K outputs, Gigabit Ethernet, USB 3.0 and Bluetooth 5.0. The Pi 3 has a single HDMI port, slower Ethernet and USB 2.0 only.

What do I need to get it running?

You need a USB-C power supply, a microSD card with an operating system, a case and a micro-HDMI cable or adapter. A heatsink or fan is recommended for sustained load.

Does it come with storage or an operating system?

No. There is no internal storage; the OS and files go on a microSD card you supply, or on a USB drive. You download and flash the OS yourself.

Can it drive two 4K monitors?

Yes, it has two micro-HDMI ports and supports dual displays up to 4K, though refresh rate drops at the highest resolutions.

Will my existing Pi HATs and cases fit?

The board keeps the same form factor as earlier models, so most HATs and cases fit. Check that a case leaves room for the new port layout and cooling.

Our take on the Raspberry Pi 4 4GB model

The Raspberry Pi 4 Model B with 4GB of RAM is a credit-card-sized single-board computer built around a 1.5GHz quad-core Broadcom BCM2711 and LPDDR4 memory. It adds dual micro-HDMI outputs for up to 4K displays, Gigabit Ethernet, two USB 3.0 ports alongside two USB 2.0 ports, dual-band 802.11ac Wi-Fi, Bluetooth 5.0 and USB-C power. It keeps the familiar board layout, so existing HATs and cases still fit. Compared with the Pi 3, it is a large step up in memory, I/O and network speed; compared with a desktop PC it is far cheaper and more power-efficient but needs a case, storage card, power supply and cooling added.

What people mention

PerformancePraisedOwners say the quad-core CPU and 4GB of RAM make it feel much faster than earlier models.
HeatCriticisedReviewers report the board runs hot under load and throttles unless a heatsink or fan is added.
PortsMixedDual micro-HDMI and USB 3.0 are welcomed, but the micro-HDMI connectors need adapters or special cables.
SetupMixedBuyers note it is a bare board that needs a power supply, case and microSD card before it works.
NetworkingPraisedGigabit Ethernet and dual-band Wi-Fi are called a clear improvement over the Pi 3.
PowerMixedSome owners mention the USB-C power input needs a capable supply and has had charger compatibility issues.
