A new version of Raspberry Pi is available on the market since June 24, 2019! A real surprise, because there was no question of an evolution of the range before 2020.
The Raspberry Pi 4 Model B comes with new features compared to the previous generation. Enough to delight computer enthusiasts and nano-computers.
For information, Raspberry Pi is a small computer at very low prices created by a team of Cambridge University professors in order to facilitate learning of computer programming to their students.
With more powerful processor and wide range of connectivity, the Raspberry Pi 4 model B as powerful as a real desktop computer, but its power consumption is paltry.
4 GB RAM according to models :
The new Raspberry Pi comes with several available configurations : 1, 2 or 4 GB of RAM depending on the models.
An increase in memory transfer speed thanks to the transition from LPDDR2 to LPDDR4.
Browsing, listening to music, watching streaming, playing online has become very easy for the Raspberry Pi 4 which does not suffer from any problem to perform various and complex tasks. Retrogaming enthusiasts will be seduced to run different OS such as Retropie.
For comparison, the 3B+ does not have 1GB in DDR3. Now you can go up to 4GB.
A more powerful processor than previous generations :
In order to make Raspberry Pi 4 more efficient, the foundation has relied on new SOC Broadcom BCM2711, quad-core Cortex-A72 (ARM v8) 64-bit to 1.5GHz, to replace the 4-core Cortex A53 with 1.4 Ghz of the previous version.
The Raspberry Pi 4 evolves to a Videocore VI graphics circuit and replaces the Videocore IV embedded on the Cortex A53 processor.
The nano-computer is now able to support 4K HEVC streams at 60 fps and manage two screens in 4K.
The HDMI port is replaced by two HDMI micro-ports that connect your nano-computer with two monitors.
Without a fan, the Raspberry Pi 4 works silently and consumes less energy than most computers. It will be wise to add an additional housing to regulate the temperature of the Raspberry and obtain the best performance.
