When the Raspberry Pi Foundation introduced the Raspberry Pi 4 last year, it was described as a "complete desktop computer", but the fact is that its performance is not powerful, even if you choose the 4GB model, you can’t run many desktop computers. Completed tasks. Today, Raspberry Pi 4 got an upgrade, and the new 8GB version joined the ranks of the product.
A long time ago, there was information that the 8GB version is possible, but as Eben Upton explained, there is a major problem that hinders its promotion, that is, the BCM2711 chip used on the Raspberry Pi 4 can handle up to 16GB of LPDDR4 SDRAM Therefore, the real obstacle to providing a larger memory version is the lack of 8GB LPDDR4 package. This problem no longer exists after 2020, and Raspberry Pi ’s partner Micron provided a suitable memory chip earlier this year.
Along with releasing a new 8 GB Raspberry Pi 4, the Raspberry Pi Foundation made a couple of noteworthy changes to its OS strategy. The company changed the name of its first-party operating system from Raspbian to "Raspberry Pi OS" and released a 64-bit OS beta to go with the existing 32-bit platform.
The newly-christened Raspberry Pi OS has a few new features, which the Pi Foundation highlighted in a blog post today. A new, preloaded Bookshelf app provides a huge library of works from the Raspberry Pi Press—including a complete collection of MagPi, HackSpace, and Wireframe magazine issues. You also get access to a number of free books.
In an effort to improve accessibility for sight impaired, Raspberry Pi OS also has a new feature called Magnifier. It helps enlarge elements on the screen to improve visibility. The new tool is available in the Recommended Applications under Universal Access.
The team also implemented a new questionnaire that will appear when launching Chromium from a newly installed image. It's a brief option survey of questions they hope will provide insight into what the user base is looking for in the OS. To read more about the new features, visit the official Raspberry Pi website.
