Talking about the design, the Raspberry Pi 4 has a lot of similarity to the Raspberry Pi 3 model B+ which is the company’s previous flagship model. It’s basically a single board computer which comes with a lot of connectors with the sizes of a deck of cards.
However, in the latest model, everything has been updated. It comes with a faster system-on-a-chip. The processor is known to make use of the Cortex-A72 architecture (quad-core 64 bit ARMv8 at 1.5 GHz). Along with it, it is also known to support h>265 hardware video decoding.
The Raspberry Pi was stuck at 512MB or 1GB of RAM for years now. But after years of a wait now, you can finally get models that come with more memory. However, the base model still starts with 1GB RAM. But if you want, you can obviously buy a model with 2GB RAM. In fact, now they even have a 4GB RAM model.
Apart from the memory even transfer speed is going to get an upgrade as the company shifts from LPDDR2 to LPDDR4.
Coming to connectivity, there are two big changes that you can get are Gigabit Ethernet. This should be able to open up a lot of potential use cases for headless Raspberry Pi devices and servers.
You also get two USB 3.0 ports along with two USB 2.0 ports. Not just that, but you will also get a USB-C port for the power brick. The company has also upgraded the Bluetooth from 4.2 to 5.0.
The main change that is made by the company is the HDMI port is gone. The company will now provide you with two HDMI ports. This will allow you to plug two 4K displays.
The rest of the features are more or less going to be the same. You will find it similar if you have used Raspberry Pi before.
