Pros & Cons

Pros

  • ✓ 8GB RAM handles Chromium, Docker stacks, and self-hosted services without swapping
  • ✓ 1.5GHz quad-core Cortex-A72, up from the Pi 3's 1.2GHz clock
  • ✓ Dual micro-HDMI outputs drive two displays at 4Kp60
  • ✓ H.265 decode plus OpenGL ES 3.0 makes it a capable media center
  • ✓ True gigabit Ethernet vs the Pi 3B+'s 300Mbps ceiling

Cons

  • ✗ Needs a 5V/3A USB-C supply; older micro-USB Pi chargers will not work
  • ✗ Micro-HDMI means new cables or adapters, not the full-size HDMI of the Pi 3
  • ✗ Higher power draw than earlier models, so passive cooling is often not enough
  • ✗ Dual micro-HDMI ports sit where the old CSI/audio layout was, breaking older cases

SpecPicks Verdict

SpecPicks scored Raspberry Pi 4 Computer Model B 8GB Single Board Computer Suitable using a rating × review-volume × price-fit model applied to our editorial and benchmark analysis across the single-board computers category. Raspberry Pi's single-board computers lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for single-board computers of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Is the 8GB model worth it over the 4GB Raspberry Pi 4?

It is if you plan to run multiple Docker containers, a self-hosted server stack, or a desktop with many Chromium tabs. For a single-purpose build like RetroPie or a Pi-hole, the 4GB or 2GB board is enough and cheaper.

What power supply does the Raspberry Pi 4 Model B need?

5V at 3.0A over USB-C. That is higher than previous Pi models, so a Pi 3 micro-USB charger will not work even with an adapter. Underpowered supplies cause throttling and random reboots.

Can it output 4K video, and to two screens at once?

Yes. The onboard GPU supports 4Kp60 and H.265 decoding, and the board has two micro-HDMI connectors for dual-screen output. You will need micro-HDMI to HDMI cables or adapters.

Does the Raspberry Pi 4 boot from a USB SSD?

Yes. The Pi 4 adds USB 3.0, and USB boot is faster and more convenient than booting from a microSD card. An SSD over the USB 3.0 port is the usual upgrade for desktop or server use.

How fast is the networking compared to the Pi 3B+?

Gigabit Ethernet on the Pi 4 is rated at 1000Mbps versus roughly 300Mbps on the Pi 3B+. Bluetooth also moves up to 5.0 with roughly double the transfer speed of the previous generation.
