The Raspberry Pi Foundation has announced the official release of an 8 GB model of the Raspberry Pi 4. The new version has been anticipated by the development team and was made available as soon as the upgrade was feasible.
According to the Raspberry Pi Foundation, almost 3 million Raspberry Pi 4 units have been sold so far. When it was first released, the team faced limitations that capped the memory capacity at 4 GB.
The Pi 4 uses a BCM2711 chip that can address a maximum of 16 GB of LPDDR4 SDRAM, but without the right package, the Pi can't make use of it. A company known as Micron released an 8 GB LPDDR4 package earlier this year, giving the Raspberry Pi Foundation team an opportunity to develop the 8 GB Raspberry Pi 4 model.
The new upgrade required small changes to the board hardware to support the new peak current requirements, including complete relocation of the switch-mode power supply and the addition of a new switcher.
If you want to get your hands on the new 8 GB model, good news! It's available to purchase now for $75 (USD). Check out the product page on the official Raspberry Pi website for more details.
