Raspberry Pi 4 is here - and this is an update.awesome. Nobody expected that the new version of the most popular single board computer will receive so many improvements. In terms of physical design, everything remains the same: Raspberry Pi 4 Model B looks exactly like the previous flagship Raspberry Pi 3 Model B +. It's a tiny computer with a bunch of connectors the size of a card deck.
Than Raspberry Pi 4 is better than the previous version
Updated literally everything. System-on-chip has become faster. The processor uses the architecture of Cortex-A72 (four core 64-bit ARMv8 with a frequency of 1.5 GHz). H.265 video hardware decoding is supported.
For many years, the Raspberry Pi "suffered" from a smallRAM size - from 512 MB to 1 GB. For the first time you can buy a model with a large amount of memory, if you need it. The basic model comes with 1 GB, but optionally you can buy a model with 2 GB of memory or even 4 GB. The memory transfer rate will also improve as the creators switched from LPDDR2 to LPDDR4.
As for the connection, now includedReal Gigabit Ethernet (not Ethernet over USB 2.0). This will open a lot of use cases for servers and other things. Two USB 3.0 and two USB 2.0 ports are also available. Bluetooth updated from 4.2 to 5.0.
Full-sized HDMI port is gone. Now, instead of it, there are two micro-HDMI ports, which allows you to connect two 4K displays, showing 60 frames per second, to one Raspberry Pi. And all this for $ 35 (base model). Models with 2 GB and 4 GB of memory cost $ 45 and $ 55, respectively.
