Raspberry Pi Zero 2 W Review: Better performance, same size

by -275 views


With the addition of a quad-core processor, while maintaining the same layout and size as the original, the Raspberry Pi Cypher two Westward is a great choice for those that need a tiny computer for a DIY projection. Now fast enough to use equally a limited desktop estimator, this new Pi Zero is easier to develop on and tin can run more complex projects than its predecessor.

  • Quad-core GPU
  • Exceptional value

Key Features

  • Size
    This entire calculator measures 65 10 30mm – that’due south little different to a stick of laptop RAM.

  • Ports
    With one Micro USB port for accessories and a Mini HDMI output for displays, you lot’ll demand adaptors to use this computer.


The Raspberry Pi Zero West was an incredible bit of kit: a total-on Pi footling bigger than a stick of laptop RAM, designed for DIY projects. If anything, the principal result was the lack of power. Today, the Raspberry Pi Aught 2 W is back to fix that, with a quad-cadre processor boosting performance to the signal where y’all can even use this equally a desktop computer.

This new mini computer is uniform with the aforementioned cases as the older model, tool, so information technology’south a simple swap-out replacement for whatsoever existing Pi Nix W computers. For general-purpose computing, the Pi 4 is a better option, for where you have a dedicated need for something smaller and more versatile it’s difficult to argue against the quality and value on display here.

Design and build

  • Same size as the original model
  • Yous’ll need adaptors
  • GPIO and CSI interfaces but no brandish interface

Lilliputian bigger than a stick of laptop ram (65 x 30mm), the Pi Naught 2 W is impressively small. It’due south actually the same size and has the same layout as the original Pi Cypher Westward, and then yous tin can use the newer reckoner with older cases. If you’ve got older Pi Zero Ws, you can just swap these out for the latest version hands.

Getting a mainboard downward to this size does require some compromises, so you’ll see no total-size ports on this model, so you’ll need to buy some adaptors: a Mini HDMI to HDMI for hooking up a display and Micro USB to USB to connect whatever peripherals. There’s too a secondary Micro USB port, which is for power. If you want composite video, and then there’southward a solder point to add this capability.

While this computer has the full GPIO header, it’s unpopulated. This saves space, only it does make playing around with new projects a petty harder, as you accept to solder cables into place when y’all’re done. I think that general development is better on a Pi 4, with the Pi Zero 2 Due west the last destination for those projects that demand a smaller computer.

Raspberry Pi Zero 2 W GPIO

This model equally the CSI-2 camera connector merely, similar its predecessor, there’s no support for the Raspberry Pi display.

At the rear of the board is the microSD card slot, which acts as both storage and the boot bulldoze for the operating organization (I ran Raspbian on this computer).

Wireless is built into the lath (that’due south the ‘W’ role of the name). The older 802.11n standard is used, so don’t expect the fastest of throughputs; however, for the kind of projects that this board is designed for, the Wi-Fi is fast enough and means that you can install the figurer practically anywhere without worrying virtually how y’all’ll become it an internet connection.


  • Quad-core processor
  • Struggles a piddling with websites
  • Much easier to work on

With its unmarried-core Broadcom BCM2835, the Pi Zero W felt very slow to utilize, and struggled to run the desktop environment. This both limited how easy the Naught Due west was to develop on, and the scale of the projects that it could run.

With the Pi Zero Due west 2, Raspberry Pi has installed a quad-cadre Cortex-A53, the same as in the older Pi 3. Here, the CPU runs at 1GHz, compared to i.4GHz on the Pi iii. Still, the upgrade is massively noticeable. It’s also a 64-flake processor, compared to the 32-bit model in the original Pi Naught W.

Boot to the Raspbian desktop, and you tin can use the full GUI without fearfulness of the computer grinding to a halt. It turns the Pi Nada 2 W from a device that is useful at the end of a projection, into a computer that you lot can use to develop your project on.

Yous can even run a spider web browser and use the internet, although some websites can bear witness to be slow to load thanks to the full general clutter that tends to come with them. Having simply 512MB of RAM is part of the trouble, and this limitation can be seen when using peculiarly demanding websites, such as YouTube. Even though the Pi Zero 2 West is technically capable of 1080p playback, YouTube was practically impossible to use reliably.

To meet what the difference was betwixt the old and new models, I ran the Sysbench CPU benchmark, gear up to run for 60 seconds, and with the maximum prime set to 10,000. Beginning, running single-core, the older Pi Zero W managed a total of 1955 events, compared to the 2871 events of the Pi Nada 2 W.

With the quad-core CPU, the Pi Aught two W tin can get fifty-fifty faster. Upping the number of threads used by Sysbench to 4, the Nada 2 W managed a full of 10850 events.

Latest deals

Should you buy information technology?

If y’all’re after a tiny computer for a custom projector, this is the model to buy: it’southward cheap but much more than powerful than the original.

If yous’re afterwards a computer to experiment with and try unlike projects, the larger and even more than powerful Pi 4 makes more sense.

Concluding Thoughts

While the Pi 4 is a better overall computer for those that want to experiment and try different projects, it’southward far larger and more than expensive than the Pi Zero 2 Due west. What y’all get here is a tiny computer with a lot more ability than its predecessor. That makes it a groovy choice where yous want a depression-power computer that doesn’t take up much space to run a specific project, such as a smart thermostat or video doorbell.

Every bit information technology’s a Micro USB port, y’all need an adaptor to plough it into a regular USB port.
