Last year the Raspberry Pi Foundation presented the
Raspberry Pi 4, a new development board definitely more powerful than
to the previous ones and in different variants with 1, 2 and 4 GB of LPDDR4 memory. At the end
February of this year, the model with 2 GB of RAM dropped in price,
placed on the same level as the 1 GB version. Today, the 1 GB drive
leaves the scene and gives way to a new version with 8 GB of RAM, that yes
places at a price of $ 75.
The Raspberry Pi 4 range therefore has a version with 2 GB
of memory at $ 35, the former top of the 4 GB range at $ 55 and the new one
8GB solution for $ 75. The rest of the board specs don’t
changes, except for the relocation of some related components
feeding as explained in
official blog. To equip the Raspberry Pi 4 with 8 GB of memory
foundation has selected Micron chips, which can meet the requirements
of the board. Potentially the Soc Broadcom BCM2711 pu address up to 16 GB
by LPDDR4, so we may see more news in the future.
The new variant of the Pi 4 could be great
utility for those who use it for “server” workloads or as a desktop PC
main, also because the foundation announced the availability in beta of Raspberry Pi OS (previously known as Raspbian), both in 32-bit version
than 64-bit. The latter allows you to map all 8 GB of memory in the
address space of a single process. At the moment the Raspberry Pi Foundation recommends to all
users to use the 32-bit version of Raspberry Pi OS or use 64-bit systems
like Ubuntu and Gentoo, as 64-bit Raspberry Pi OS still in development and
not free from problems.
