How Upgrading Raspberry Pi 4 to Bullseye Will Make It Run Fast – Guide
Update your Raspberry Pi 4 OS to the latest Bullseye edition for a performance boost. This week, the official Raspberry Pi operating system had its first update based on Linux Debian version 11, also known as Bullseye. Among some major changes, one update stands out: the standard turbo mode clock has been increased from 1.5GHz to 1.8GHz for recent Raspberry Pi 4 devices. The result is faster operating speeds, making this update worthwhile.
Which Pi qualifies?
If you have any 8GB Raspberry Pi 4, this update will apply to you. Alternatively, if you have a 2GB or 4GB card with a switcher, ie a dedicated switched power supply for the SoC core voltage rail, you will also get this speed boost. Even if you don’t have a recent model that qualifies for the new standard turbo-clock speed, Bullseye’s new update will support overclocking on older models, calculating the best voltage to apply in that case. Raspberry Pi Trading CEO Eben Upton acknowledges that the older Raspberry Pi 4 launch variant earned a reputation for overclocking capability, so it offered a way to manually replicate the new operating point on it. This can be done by adding the following line to the config.txt file: arm_freq = 1800 However, this comes with a word of caution: “Playing with clocks and voltages can make your SD card (temporarily) unbootable, so make sure you have another card (or another computer) on hand that you can boot to. restore your config.txt to common sense,” writes Eben Upton in the latest Raspberry Pi press release.
What else is new?
Some of the major changes with the Bullseye update include the removal of the Raspberry Pi display and camera support in favor of Linux standards. The new camera the driver will be the Linux API libcamera, while the new display driver will be KMS, previously an experimental option available in previous versions of the Raspberry Pi OS. This change is a change from the proprietary closed source code of the Raspberry Pi in favor of openness up development for third parties and making the whole process a little easier. Another significant change is an upgrade from GTK + 2 to GTK + 3, bringing the Raspberry Pi desktop environment more in line with other Debian applications. Other changes include a new window manager called mutter, an update to the way built-in notifications work, a new updater plugin, and simplified file manager options.
Score Bullseye and get faster speed
Upgrading your Raspberry Pi 4 to Debian Bullseye should make it faster, making this upgrade something to consider. Even if you have an older Pi 4 model, thanks to the new update, overclocking will be supported with the new operating system selecting the best voltage to use. If you want to go ahead and upgrade to the latest Raspberry Pi OS, Eben Upton recommends downloading a new image, reinstalling all applications, and transferring your data via the current OS image. It’s not very difficult and there are many different ways to do this.
