Photos: What is the Raspberry Pi 4 Model B? A closer look at the new board and what it can do

Same size, different layout

As you can see, while the Raspberry Pi 4 Model B, on the left, is the same size as the Raspberry Pi 3 Model B+, it has a different layout.

The change has been necessary to incorporate the dual micro-HMDI ports on the board.

The new layout means side panels in cases for older Pi boards won't fit correctly. I also found the board overheated when playing video while using an older case, with the computer throttling performance to reduce temperature.
