There’s a lot to like about the Raspberry Pi 4: Up to 4GB of on-board memory, a faster quad-core CPU, support for dual 4K displays via a pair of micro-HDMI ports, and more. Let’s take a look at the Pi 4 and see what its got under-the-hood.
1 – Memory
The RPi4 now comes with a choice of memory: 1GB, 2GB, or a 4GB model. The more memory means you’re able to have more applications open, without degrading the overall performance of the Pi.
2 – USB 3.0
The inclusion of a couple of USB 3.0 ports is an excellent choice. The faster data bandwidth of USB 3.0 will, for example, enable the Pi to read and write that data, both to and from an external drive, far quicker than ever before.
3 – Dual Display
In a shock move the team behind the Pi 4 decided to include a pair of micro-HDMI ports. This means you’re able to connect two monitors for dual-screen displays.
4 – Improved Processing
The 1.5GHz, 64-bit quad-core ARM Cortex-A72 CPU, is the driving force behind the Pi 4’s improved performance. Thanks to this CPU, you’re able to enjoy faster apps and content.
5 – Improved GPU
With a VideoCore 6 GPU, the Pi 4 is capable of 4K resolutions at 60FPS (Frames per Second), and thanks to some tweaks to the video codes in both Raspbian and the version of VLC packaged with Raspbian, the Pi 4 is now a pretty decent media device.
6 – Connectivity
Now with Bluetooth 5.0, alongside 802.11 b/g/n/ac wireless, and a gigabit Ethernet port, the Pi 4 is certainly well connected.
Raspberry Pi 3 B+ Pricing
Since the Raspberry Pi 4 now offers three different versions within the new model, it stands to reason that the pricing for it has changed slightly. The 1GB memory version of the Pi 4 is priced at around £34, depending on where you shop. The 2GB memory version is on sale for around £44, while the top-end, 4GB memory version will set you back in the region of £54. Together with the cost of the Pi itself, you will also need to factor in one or two micro-HDMI cables (depending on whether you want to connect one or two monitors), each costing roughly £5-plus.
