A long-awaited model for the Raspberry Pi 4 Model B has been a model with 8GB RAM. Although the maximum memory capacity supported by the BCM2711 was 16GB, there was no compatible 8GB LPDDR4 package when it was released in 2019, so RAM could only be selected from 3 types of 1GB / 2GB / 4GB. However, expectations for the '8GB RAM-equipped model' were rising because of the playfulness that the '8GB RAM-equipped model' was drawn in the Rasberry Pi official beginner's guide as if it had already been released.

The following Raspberry Pi 4 Model B user guide says 'Raspberry Pi 4 Model B 1GB, 2GB, 4GB + 8GB variants', as if '8GB RAM installed model' has already been released. It's a gimmick.

Then on May 28, 2020, the Raspberry Pi 4 Model B with 8GB RAM finally became a reality. The model with 8GB RAM costs $ 75 (about 8100 yen). At the same time, the price of the model with 2GB RAM was also reduced from $ 45 (about 4800 yen) to $ 35 (about 3800 yen).

It is the same as the conventional Raspberry Pi 4 Model B except that it has 8GB RAM, but the required power has increased, so the switch mode power supply that was located next to the USB 2.0 socket was replaced by the USB-C power connector. Has been installed on the board and the placement on the board has changed slightly.

The conventional standard OS 'Raspbian' is built as a 32-bit OS, and can be used with this Raspberry Pi equipped with 8GB memory. However, due to the 32-bit limitation, a single process can only use up to 3GB of memory. Therefore, in order to fully utilize the 8GB memory, you need to use a 64-bit version such as Ubuntu or Gentoo Linux .

Therefore, the standard OS Raspbian has been renamed to ' Raspberry Pi OS ', and not only the 32-bit version but also the 64-bit version will be released. The initial beta version of the 64-bit Raspberry Pi OS can be downloaded from the following page.
