When the Raspberry Pi Foundation launched the Raspberry Pi 4 last year, they described it as a “complete desktop computer”, but the truth is that it is not so powerful that, even if you choose the 4GB model, it cannot perform many of the tasks that can be done with a desktop computer. Today, the Raspberry Pi 4 gets an upgrade with a new 8GB version that will be added to the range of products.
Raspberry Pi 4 is equipped with the BCM2711 SoC, which is a 64-bit chip, the Raspberry Pi can actually support up to 16 GB of memory, so to improve data throughput performance and to improve its services to meet expectations of some geeks, or to make a wide range home network server, or users who need to open multiple web windows at the same time, Raspberry Pi 4 now has 8GB LPDDR4 version, at a price of $ 75.
The 8GB model was actually available earlier this year, but like everything, the COVID 19 pandemic caused a delay. The new Raspberry Pie 4 has been re-designed to accommodate the extra peak loads required for the enhanced memory package. Therefore the power supply assembly has been redesigned and the switch mode power supply on the right side of the board next to the USB 2.0 socket has been removed and replaced by a USB C power supply connector. Apart from that everything is the same as with the other models.
In addition to the hardware changes, Raspberry Pi has also updated its software to include a larger memory version, which is the 64-bit version of Raspberry Pi OS. In the past, Raspberry Pi’s official system used a 32-bit LPAE kernel and user environment, but with the arrival of hardware such as the SoC, which supports 64-bit computing and 8 GB of memory in the Raspberry Pi 4, the 64-bit system will also have to keep pace.
