Raspberry Pi 4 vs Raspberry Pi 3 “A New Slice of Pi ”

Who is ready for another piece of pi? Every time a new Raspberry Pi comes out, there is excitement from all angles. This time is no different, in fact, it might be more exciting. Back in January, the raspberry pi foundation mentioned: “This will be the last Pi of its kind”. The new Raspberry Pi 4 Model B has launched today, with some new and much-anticipated features. Really amazing!

The Raspberry Pi 4 Model B is the first pi with a 28nm processor. Moving to the 28nm from the 40nm based products allows the new pi to utilize a much more powerful processing core and have better I/O performance. This new pi could be a full PC replacement. Every engineer and/or maker in the world requires a dual monitor display for desktops. Let’s see how the new pi can increase productivity and allow for writing python and web browsing on two separate screens.

Here is the dirt…. What has changed,hoho? What is missing? How has the pi foundation listened?

How do I think about this new Raspberry Pi ???

In my own opinion, adding the USB C port was a great move. Hopefully, the rest of the world will adopt this strategy. I am ready to be done carrying so many cables with me. They have also increased the input current to 3 Amps to handle the increased power needed to run.

Great Connectivity – the adoption of Bluetooth 5.0 has been incorporated, which will give faster connection speeds along with a more stable Bluetooth experience. Replacing 2 of the 4 existing USB 2.0 ports with USB 3.0 gives expanded capabilities and they have added true Gigabit Ethernet.

Incorporating two micro HDMI ports instead of one full size port gives the capability to utilize two monitors on your pi or allow for dual monitors in a kiosk or display stand. This was asked for by many of the pi users and the Raspberry Pi foundation listened. The option to output 4K video is another addition that was not on any pi previously. You can have one video output at 4K at 60fps or two at 4K at 30 fps.

Now for the options, yes this has options just like buying a new car. You will have the ability to select the memory of your choice. 1GB, 2GB, and 4 GB are the choices available.

This new Pi will enable you to create to the n’th degree with the increased speed, functionality, and memory.

You may ask, how does this compare to the previous Pi 3 boards? Here is a breakdown between the Raspberry Pi 3 Model B, Raspberry Pi Model B+, and the new Raspberry Pi 4 Model B:
